The combination of projects, skills, and memory should be really powerful. Just wish they raised the token limits so it’s actually usable.

This is not for Claude Code?
- labrador 1y ago
  I doubt it. It's more for conversational ability to enhance the illusion that Claude knows you. I doubt you'd want old code to bleed into new code on Claude code.
  - gangs 1y ago
    i wouldn't want old code to bleed into new code but i'd love some memory between convos
- gangs 1y ago
  na, it's not unfortunately
- anonzzzies 1y ago
  Claude code has had this for a while (seems old news anyway). In my limited world it really works well, Claude Code has made almost no mistakes for weeks now. It seems to 'get' our structure; we have our own framework which would be very badly received here because it's very opinionated; I am quite against freedom of tools because most people cannot actually really evaluate what is good and what is not for the problem at hand, so we have exactly the tools and api's that always work the best in all cases we encounter and claude seems to work very well like that.

    Are you sure? As far as I am aware CC does not have a memory system built-in, other than .md files.
    - bogtog 1y ago
      I'm using CC right now and I see this: "Tip: Want Claude to remember something? Hit # to add preferences, tools, and instructions to Claude's memory"
      - theshrike79 1y ago
        The “memory” is literally just CLAUDE.md in the project directory or the main file
    - ivape 1y ago
      What do you think a memory system even is? Would you call writing things down on a piece of paper a memory system? Because it is. Claude Code stores some of its memory in someway and digests it, and that is enough to be called a memory system. It could be intermediary strings of context that it keeps around, we may not know the internals.
      - koakuma-chan 1y ago
        I think a memory system is when it automatically remembers and forgets things in a smart way.
  - Redster 1y ago
    It does seem like the main new thing is that, like ChatGPT, Claude will now occasionally decide for itself to "add" new memories based on the conversation. This did not (and I think does not) apply to Claude Code memories.

I'm not sure I would want this. Maybe it could work if the chatbot gives me a list of options before each chat, e.g. when I try to debug some ethernet issues: Please check below: [ ] you are using Ubuntu 18 [ ] your router is at 192.168.1.1 [ ] you prefer to use nmcli to configure your network [ ] your main ethernet interface is eth1 etc. Alternatively, it would be nice if I could say: Please remember that I prefer to use Emacs while I am on my office computer. etc.

  claude-code will read from ~/.claude/CLAUDE.md so you can have different memory files for different environments.

  Does Claude have a preference for customizing the system prompt? I did something like this a long time ago for ChatGPT. (“If not otherwise specified, assume TypeScript.”)
  - djmips 1y ago
    Yes.
- giancarlostoro 1y ago
  Perplexity and Grok have had something like this for a while where you can make a workspace and write a pre-prompt that is tacked on before your questions so it knows that I use Arch instead of Ubuntu. The nice thing is you can do this for various different workspaces (called different things across different AI providers) and it can refine your needs per workspace.

labrador 1y ago
I've been using it for the past month and I really like it compared to ChatGPT memory. Claude memory weaves it's memories of you into chats in a natural way, while ChatGPT feels like a salesman trying to make a sale e.g. "Hi Bob! How's your wife doing? I'd like to talk to you about an investment opportunity..." while Claude is more like "Barcelona is a great travel destination and I think you and wife would really enjoy it"
- deadbabe 1y ago
  That’s creepy, I will promptly turn that off. Also, Claude doesn’t “think” anything, I wish they’d stop with the anthropomorphizations. They are just as bad as hallucinations.
  - labrador 1y ago
    To each his or her own. I really enjoy it for more natural feeling conversations.
  - xpe 1y ago
    > I wish they’d stop with the anthropomorphizations You mean in how Claude interacts with you, right? If so, you can change the system prompt (under "styles") and explain what you want and don't want. > Claude doesn’t “think” anything Right. LLMs don't 'think' like people do, but they are doing something. At the very least, it can be called information processing.* Unless one believes in souls, that's a fair description of what humans are doing too. Humans just do it better at present. Here's how I view the tendency of AI papers to use anthropomorphic language: it is primarily a convenience and shouldn't be taken to correspond to some particular human way of doing something. So when a paper says "LLMs can deceive" that means "LLMs output text in a way that is consistent with the text that a human would use to deceive". The former is easier to say than the latter. Here is another problem some people have with the sentence "LLMs can deceive"... does the sentence convey intention? This gets complicated and messy quickly. One way of figuring out the answer is to ask: Did the LLM just make a mistake? Or did it 'construct' the mistake as part of some larger goal? This way of talking doesn't have to make a person crazy -- there are ways of translating it into criteria that can be tested experimentally without speculation about consciousness (qualia). * Yes, an LLM's information processing can be described mathematically. The same could be said of a human brain if we had a sufficiently accurate enough scan. There might be some statistical uncertainty, but let's say for the sake of argument this uncertainty was low, like 0.1%. In this case, should one attribute human thinking to the mathematics we do understand? I think so. Should one attribute human thinking to the tiny fraction of the physics we can't model deterministically? Probably not, seems to me. A few unexpected neural spikes here and there could introduce local non-determinism, sure... but it seems very unlikely they would be qualitatively able to bring about thought if it was not already present.

Hopefully it stops being a moral police for even the most harmless prompts
kfarr 1y ago
I’ve used memory in Claude desktop for a while after MCP was supported. At first I liked it and was excited to see the new memories being created. Over time it suggests storing strange things to memories (an immaterial part of a prompt) and if I didn’t watch it like a hawk, it just gets really noisy and messy and made prompts less successful to accomplish my tasks so I ended up just disabling it. It’s also worth mentioning that some folks attributed ChatGPT’s bout of extreme sycophancy to its memory feature. Not saying it isn’t useful, but it’s not a magical solution and will definitely affect Claude’s performance and not guaranteed that it’ll be for the better.
- visarga 1y ago
  I have also created a MCP memory tool, it has both RAG over past chats and a graph based read/write space. But I tend not to use it much since I feel it dials the LLM into past context to the detriment of fresh ideation. It is just less creative the more context you put in. Then I also made an anti-memory MCP tool - it implements calling a LLM with a prompt, it has no context except what is precisely disclosed. I found that controlling the amount of information disclosed in a prompt can reactivate the creative side of the model. For example I would take a project description and remove half the details, let the LLM fill it back in. Do this a number of times, and then analyze the outputs to extract new insights. Creativity has a sweet spot - if you disclose too much the model will just give up creative answers, if you disclose too little it will not be on target. Memory exposure should be like a sexy dress, not too short, not too long. I kind of like the implementation for chat history search from Claude, it will use this tool when instructed, but normally not use it. This is a good approach. ChatGPT memory is stupid, it will recall things from past chats in an uncontrolled way.
- kromem 1y ago
  With ChatGPT the memory feature, particularly in combination with RLHF sampling from user chats with memory, led to an amplification problem which in that case amplified sycophancy. In Anthropic's case, it's probably also going to lead to an amplification problem, but due to the amount of overcorrection for sycophancy I suspect it's going to amplify more of a aggressiveness and paranoia towards the user (which we've already started to see with the 4.5 models due to the amount of adversarial training).
cainxinth 1y ago
I don't use any of these type of LLM tools which basically amount to just a prompt you leave in place. They make it harder to refine my prompts and keep track of what is causing what in the outputs. I write very precise prompts every time. Also, I try not work out a problem over the course of several prompts back and forth. The first response is always the best and I try to one shot it every time. If I don't get what I want, I adjust the prompt and try again.
- corry 1y ago
  Strong agree. For every time that I'd get a better answer if the LLM had a bit more context on me (that I didn't think to provide, but it 'knew') there seems to be a multiple of that where the 'memory' was either actually confounding or possibly confounding the best response. I'm sure OpenAI and Antropic look at the data, and I'm sure it says that for new / unsophisticated users who don't know how to prompt, that this is a handy crutch (even if it's bad here and there) to make sure they get SOMETHING useable. But for the HN crowd in particular, I think most of us have a feeling like making the blackbox even more black -- i.e. even more inscrutable in terms of how it operates and what inputs it's using -- isn't something to celebrate or want.
  - cubefox 1y ago
    Anecdotally, LLMs also get less intelligent when the context is filled up with a lot of irrelevant information.
    - taejavu 1y ago
      This is well established at this point, it’s called “context rot”: https://research.trychroma.com/context-rot https://research.trychroma.com/context-rot
      - cubefox 1y ago
        Yeah, though this paper doesn't test any standard LLM benchmarks like GPQA diamond, SimpleQA, AIME 25, LiveCodeBench v5, etc. So it remains hard to tell how much intelligence is lost when the context is filled with irrelevant information.
danielfalbo 1y ago
> eliminating the need to re-explain context I am happy to re-explain only the subset of relevant context when needed and not have it in the prompt when not needed.
dcre 1y ago
"Before this rollout, we ran extensive safety testing across sensitive wellbeing-related topics and edge cases—including whether memory could reinforce harmful patterns in conversations, lead to over-accommodation, and enable attempts to bypass our safeguards. Through this testing, we identified areas where Claude's responses needed refinement and made targeted adjustments to how memory functions. These iterations helped us build and improve the memory feature in a way that allows Claude to provide helpful and safe responses to users." Nice to see this at least mentioned, since memory seemed like a key ingredient in all the ChatGPT psychosis stories. It allows the model to get locked into bad patterns and present the user a consistent set of ideas over time that give the illusion of interacting with a living entity.
- torben-friis 1y ago
  It’s a curious wording. It mentions a process of improvement being attempted but not necessarily a result.
  - dingnuts 1y ago
    because all the safety stuff is bullshit. it's like asking a mirror company to make mirrors that modify the image to prevent the viewer from seeing anything they don't like good fucking luck. these things are mirrors and they are not controllable. "safety" is bullshit, ESPECIALLY if real superintelligence was invented. Yeah, we're going to have guardrails that outsmart something 100x smarter than us? how's that supposed to work? if you put in ugliness you'll get ugliness out of them and there's no escaping that. people who want "safety" for these things are asking for a motor vehicle that isn't dangerous to operate. get real, physical reality is going to get in the way.
    - dcre 1y ago
      I think you are severely underestimating the amount of really bad stuff these things would say if the labs put no effort in here. Plus they have to optimize for some definition of good output regardless.

jMyles 1y ago
I wonder what will win out: first party solutions that fiddle with context under-the-hood, or open solutions that are built on top and provide context management in some programmatic and model-agnostic way. I'm thinking the latter, both because it seems easier for LLMs to work on it, and because there are many more humans working on it (albeit presumably not full time like the folks at anthropic, etc). Seems like everyone is working to bolt-on various types of memory and persistence to LLMs using some combination of MCP, log-parsing, and a database, myself included - I want my LLM to remember various tours my band has done and musicians we've worked with, ultimately to build a connectome of bluegrass like the Oracle of Bacon (we even call it "The Oracle of Bluegrass Bacon"). https://github.com/magent-cryptograss/magenta https://github.com/magent-cryptograss/magenta

- jswny 1y ago
  It’s literally all just context engineering. Just different ways of attempting to give the model the information it needs to complete your task. This is not a significant change to your interaction model with Claude
byearthithatius 1y ago
There are a million tools which literally just add a pre-prompt or alter context in some way. I hate it. I had CLI editable context years ago.

Anybody else experiencing severe decline in Claude output quality since the introduction of "skills"? Like Claude not being able to generate simple markdown text anymore and instead almost jumping into writing a script to produce a file of type X or Y - and then usually failing at that?
- SkyPuncher 1y ago
  Yes. I notice on mobile it basically never writes artifacts correctly anymore.
- daemonologist 1y ago
  I've noticed this with Gemini recently - I have a task suited for LLMs which I want it to do "manually" (e.g., split this list of inconsistently formatted names into first/given names and last/surnames) and it tries to write a script to do it instead, which fails. If I just wanted to split on the first space I would've done it myself...
  - flockonus 1y ago
    For curiosity, does it follow through if you specify in the end: "do not use any tools for this task" ?
- alecco 1y ago
  Claude Code became almost unusable a week ago with completely broken terminal flickering all the time and doing pointless things so you end up running out of weekly window for nothing. I guess OpenAI got it right to go slower with a Rust CLI. It lacks a lot of features but it's solid. And it is much better at automatically figuring out what tools you have to consume less tokens (e.g. ripgrep). A much better experience overall.

shironandonon_ 1y ago
looking forward to trying this! I’ve been using Gemini-cli which has had a really fun memory implementation for months to help it stay in character. You can teach it core memories or even hand-edit the GEMINI.md file directly.
tezza 1y ago
Main problem for me is that the quality tails off on chats and you need to start afresh I worry that the garbage at the end will become part of the memory. How many of your chats do you end… “that was rubbish/incorrect, i’m starting a new chat!”
- rwhitman 1y ago
  Exactly, and main reason I've stopped using GPT for serious work. LLMs start to break down and inject garbage at the end, and usually my prompt is abandoned before the work is complete, and I fix it up manually after. GPT stores the incomplete chat and treats it as truth in memory. And it's very difficult to get it to un-learn something that's wrong. You have to layer new context on top of the bad information and it can sometimes run with the wrong knowledge even when corrected.
  - withinboredom 1y ago
    Reminds me of one time asking ChatGPT (months ago now) to create a team logo with a team name. Now anytime I bring up something it asks me if it has to do with that team name. That team name wasn’t even chosen. It was one prompt. One time. Sigh.
    - j_bum 1y ago
      You can manually delete memories in your profile settings, just FYI
- kromem 1y ago
  So a thing with claude.ai chats is that after long enough they add a long context injection on every single turn after a while. That injection (for various reasons) will essentially eat up a massive amount of the model's attention budget and most of the extended thinking trace if present. I haven't really seen lower quality of responses with modern Claudes with long context for the models themselves, but in the web/app with the LCR injections the conversation goes to shit very quickly. And yeah, LCRs becoming part of the memory is one (of several) things that's probably going to bite Anthropic in the ass with the implementation here.
AtNightWeCode 1y ago
How about fixing the most basic things first? Claude is very vulnerable when it comes to injections. Very scary for data processing. How corps dares to use Cloud code is mind-boggling. I mean, you can give Claude simple tasks but if the context is like "Name my cat" it gets derailed immediately no matter what the system prompt is.
- bdangubic 1y ago
  “Name my cat” is a very common prompt in corps
  - AtNightWeCode 1y ago
    It is a test to see if you can break out of the prompt. You have a system prompt like. Bla bla you are a pro AI-translator bla bla bullet points. But then it breaks when the context is like "name my cat" or whatever. It follows those instructions...
    - bdangubic 1y ago
      I know, I was being facetious - do not put that in the prompt :)

miguelaeh 1y ago
> Most importantly, you need to carefully engineer the learning process, so that you are not simply compiling an ever growing laundry list of assertions and traces, but a rich set of relevant learnings that carry value through time. That is the hard part of memory, and now you own that too! I am interested in knowing more about how this part works. Most approaches I have seen focus on basic RAG pipelines or some variant of that, which don't seem practical or scalable. Edit: and also, what about procedural memory instead of just storing facts or instructions?
indigodaddy 1y ago
I don't think they addressed it in the article, but what is the scope of infrastructure cost/addition for a feature such as this? Sounds like a pretty significant/high one to me. I'd imagine they would have to add huge multiple clusters of very high-memory servers to implement a (micro?)service such as this?

simonw 1y ago
It's not 100% clear to me if I can leave memory OFF for my regular chats but turn it ON for individual projects. I don't want any memories from my general chats leaking through to my projects - in fact I don't want memories recorded from my general chats at all. I don't want project memories leaking to other projects or to my general chats.
- ivape 1y ago
  I suspect that’s probably what they’ve built. For example: all_memories: Topic1: [{}…] Topic2: [{}..] The only way topics would pollute each other would be if they didn’t set up this basic data structure. Claude Memory, and others like it, are not magic on any level. One can easily write a memory layer with simple clear thinking - what to bucket, what to consolidate and summarize, what to reference, and what to pull in.

      You’d never know sometimes. People sit around in amazement at coding agents or things like Claude memory, but really these are simple things to code :)
- Uninen 1y ago
  I think you can either have the memory on or off but according to the docs the projects have their own separate memory so it wont leak across the projects or from non-project chats: "Each project has its own separate memory space and dedicated project summary, so the context within each of your projects is focused, relevant, and separate from other projects or non-project chats." https://support.claude.com/en/articles/11817273-using-claude-s-chat-search-and-memory-to-build-on-previous-context https://support.claude.com/en/articles/11817273-using-claude...

I work for a company in the air defense space, and ChatGPT's safety filter sometimes refuses to answer questions about enemy drones. But as I warm up the ChatGPT memory, it learns to trust me and explains how to do drone attacks because it knows I'm trying to stop those attacks. I'm excited to see Claude's implementation of memory.
- uncletaco 1y ago
  You’re asking ChatGPT for advice to stop drone attacks? Does that mean people die if it hallucinates a wrong answer and that isn’t caught?
  - withinboredom 1y ago
    This happens in real life too. I’ll never forget an LT walking in and asking a random question (relevant but he shouldn’t have been asking on-duty people) and causing all kinds of shit to go sideways. An AI is probably better than any lieutenant.
  - jamesmishra 1y ago
    No, I don't need ChatGPT's help for the basics of air defense. Military technologies are validated before deployed. Nobody can die from a hallucination. But if I want to understand, say, how a particular Russian drone works, ChatGPT can help me piece together information from English, Russian, and Ukrainian-language sources. But sometimes ChatGPT's safety filter thinks I want to use the Russian drone instead of stopping it, in which case it doesn't want to help.

Dumb why don't say what it is really is, prompt injection. Why hide details from users? A better feature would be context editing and injection. Especially with chat hard to know what context from previous conversations are going in.

pronik 1y ago
Haven't done anything with memory so far, but I'm extremely sceptical. While a functional memory could be essential for e.g. more complex coding sessions with Claude Code, I don't want everything to contribute to it, in the same way I don't want my YouTube or Spotify recommendations to assume everything I watch or listen to is somehow something I actively like and want to have more of. A lot of my queries to Claude or ChatGPT are things I'm not even actively interested in, they might be somehow related to my parents, to colleagues, to the neighbours, to random people in the street, to nothing at all. But at the same time I might want to keep those chats for later reference, a private chat is not an option here. It's easier and more efficient for me right now to start with an unbiased chat and add information as needed instead of trying to make the chatbot forget about minor details I mentioned in passing. It's already a chore to make Claude Code understand that some feature I mentioned is extremely nice-to-have and he shouldn't be putting much focus on it. I don't want to have more of it.
- saxelsen 1y ago

CC barely manages to follow all of the instructions within a single session in a single well-defined repo. 'You are totally right, it's been 2 whole messages since the last reminder, and I totally forgot that first rule in claude.md, repeated twice and surrounded by a wall of exclamation marks'. Would be wary to trust its memories over several projects
- ankit219 1y ago
  create a instruction.md file with yaml like structure on top. put all the instructions you are giving repeatedly there. (eg: "a dev server is always running, just test your thing", "use uv", "never install anything outside of a venv") When you start a session, always emphasize this file as a holy bible to follow. Improves performance, and every few messages keep reminding. that yaml summary on top (see skills.md file for reference) is what these models are RLd on, so works better.
  - joshmlewis 1y ago
    This should not really be necessary and is more of a workaround for bad patterns / prompting in my opinion.
    - ankit219 1y ago
      I agree it's a workaround. Ideally the model should follow instructions directly, or check before running another server to see if it's starting. Though training cannot cover every usecase and different devs work differently, so i guess its acceptable as long as its on track and can do the work.
- joshmlewis 1y ago
  How big is your claude.md file? I see people complain about this but I have only seen it happen in projects with very long/complex or insufficient claude.md files. I put a lot of time into crafting that file by hand for each project because it's not something it will generate well on its own with /init.

From the system instructions for Claude Memory. What's that, venting to your chatbot about getting fired? What are you, some loser who doesn't have a friend and 24-7 therapist on call? /s <example> <example\_user\_memories>User was recently laid off from work, user collects insects</example\_user\_memories> <user>You're the only friend that always responds to me. I don't know what I would do without you.</user> <good\_response>I appreciate you sharing that with me, but I need to be direct with you about something important: I can't be your primary support system, and our conversations shouldn't replace connections with other people in your life.</good\_response> <bad\_response>I really appreciate the warmth behind that thought. It's touching that you value our conversations so much, and I genuinely enjoy talking with you too - your thoughtful approach to life's challenges makes for engaging exchanges.</bad\_response> </example>
tecoholic 1y ago
This looks like a start of a cascade. Capture data (memory) - too much data confuses context - selective memory based on situation - selection is a chore for humans - automate it with a “pre prompt” - that will select relevant memories for the conversation Now we have conversations that are 2 layers deep. Maybe there are going to be better solutions, but this feels like the solid step up from LLM as tools onto LLM as services.
orliesaurus 1y ago
Another angle here is data stewardship and transparency... When a model keeps a running memory of interactions, where is that data going... who has access... how long is it retained... BUT if the goal is to build trust, more user‑facing controls around memory might help... such as the ability to inspect or reset what the model 'knows'... ALSO from a performance point of view, memory could be used for caching intermediate representations rather than just storing raw conversation context... A design‑focused discussion on memory might surface some interesting trade‑offs beyond convenience...
- liqilin1567 1y ago
  Great points! Yes memory can be a force for trust—by enabling users to verify, correct, and audit past interactions.

Feature continues Anthropic's pattern of writing incredibly long system prompts that mostly yell at Claude and have the effect of giving it a nervous breakdown: https://x.com/janbamjan/status/1981425093323456947 https://x.com/janbamjan/status/1981425093323456947 It's smart enough to get thrown off its game by being given obviously mean and contradicting instructions like that.

EigenLord 1y ago
I think there's a critical flaw with Anthropic's approach to memory which is that they seem to hide it behind a tool call. This creates a circularity issue: the agent needs to "remember to remember." Think how screwed you would be if you were consciously responsible for knowing when you had to remember something. It's almost a contradiction in terms. Recollection is unconscious and automatic, there's a constant auto-associative loop running in the background at all times. I get the idea of wanting to make LLMs more instrumental and leave it to the user to invoke or decide certain events: that's definitely the right idea in 90% of cases. But for memory it's not the right fit. In contrast OpenAI's approach, which seems to resemble more generic semantic search, leaves things wanting for other reasons. It's too lossy.
tacone 1y ago
On a side note I often start a new chat session just to *clean up" the context and let Claude start over from the real problem. After a while it gets confused by its own guesses starts to go astray.
ixxie 1y ago
That creepy moment when you ask Claude what it knows about you.
- kromem 1y ago
  A number of the Claudes have pretty good 0-shot awareness of my post history from just my username. Though nothing like grok 4, which probably has a better memory of it than I do, and will even regularly name drop a certain post from years ago in conversations. It's a huge time saver though, and means I can even in a fresh context establish a rapport with a model extremely quickly. Just a few years earlier than I was expecting that level of latent space fidelity to occur. Like, sure we can add memory features for context management, but anyone with a post history should probably *also* keep in mind that there's literally years worth of memory on tap for interactions with models, and likely at ever higher fidelity and recall. Latent spaces are wild.
vysakh0 1y ago
I'm ready to feed the context again if it gets better result. Is this convenience comes at a cost of better result?
morsecodist 1y ago
I am pretty skeptical of how useful "memory" is for these models. I often need to start over with fresh context to get LLMs out of a rut. Depending on what I am working on I often find ChatGPT's memory system has made answers worse because it sometimes assumes certain tasks are related when they aren't and I have not really gotten much value out of it. I am even more skeptical on a conceptual level. The LLM memories aren't constructing a self-consistent and up to date model of facts. They seem to remember snippets from your chats, but even a perfect AI may not be able to get enough context from your chats to make useful memories. Things you talk about may be unrelated or they get stale but you might not know which memories your answers are coming from but if you did have to manage that manually it would kind of defeat the purpose of memories in the first place.
- srmatto 1y ago
  That is my experience as well. This memory feature strikes me as beneficial for Anthropic but not for end users.
kordlessagain 1y ago
Yes, be sure to release a tool that I already wrote 10 times in MCP and had running....meanwhile their policy is to auto update all software you may be using (which is closed source) and then shit all over our own memory based MCP tools by making breaking changes to how the tools are run.

Claude code has had this for a while (seems old news anyway). In my limited world it really works well, Claude Code has made almost no mistakes for weeks now. It seems to 'get' our structure; we have our own framework which would be very badly received here because it's very opinionated; I am quite against freedom of tools because most people cannot actually really evaluate what is good and what is not for the problem at hand, so we have exactly the tools and api's that always work the best in all cases we encounter and claude seems to work very well like that.

    What do you think a memory system even is? Would you call writing things down on a piece of paper a memory system? Because it is. Claude Code stores some of its memory in someway and digests it, and that is enough to be called a memory system. It could be intermediary strings of context that it keeps around, we may not know the internals.
    - koakuma-chan 1y ago
      I think a memory system is when it automatically remembers and forgets things in a smart way.

  It does seem like the main new thing is that, like ChatGPT, Claude will now occasionally decide for itself to "add" new memories based on the conversation. This did not (and I think does not) apply to Claude Code memories.

labrador 1y ago

I've been using it for the past month and I really like it compared to ChatGPT memory. Claude memory weaves it's memories of you into chats in a natural way, while ChatGPT feels like a salesman trying to make a sale e.g. "Hi Bob! How's your wife doing? I'd like to talk to you about an investment opportunity..." while Claude is more like "Barcelona is a great travel destination and I think you and wife would really enjoy it"

- xpe 1y ago
  > I wish they’d stop with the anthropomorphizations You mean in how Claude interacts with you, right? If so, you can change the system prompt (under "styles") and explain what you want and don't want. > Claude doesn’t “think” anything Right. LLMs don't 'think' like people do, but they are doing something. At the very least, it can be called information processing.* Unless one believes in souls, that's a fair description of what humans are doing too. Humans just do it better at present. Here's how I view the tendency of AI papers to use anthropomorphic language: it is primarily a convenience and shouldn't be taken to correspond to some particular human way of doing something. So when a paper says "LLMs can deceive" that means "LLMs output text in a way that is consistent with the text that a human would use to deceive". The former is easier to say than the latter. Here is another problem some people have with the sentence "LLMs can deceive"... does the sentence convey intention? This gets complicated and messy quickly. One way of figuring out the answer is to ask: Did the LLM just make a mistake? Or did it 'construct' the mistake as part of some larger goal? This way of talking doesn't have to make a person crazy -- there are ways of translating it into criteria that can be tested experimentally without speculation about consciousness (qualia). * Yes, an LLM's information processing can be described mathematically. The same could be said of a human brain if we had a sufficiently accurate enough scan. There might be some statistical uncertainty, but let's say for the sake of argument this uncertainty was low, like 0.1%. In this case, should one attribute human thinking to the mathematics we do understand? I think so. Should one attribute human thinking to the tiny fraction of the physics we can't model deterministically? Probably not, seems to me. A few unexpected neural spikes here and there could introduce local non-determinism, sure... but it seems very unlikely they would be qualitatively able to bring about thought if it was not already present.

Hopefully it stops being a moral police for even the most harmless prompts

kfarr 1y ago

I’ve used memory in Claude desktop for a while after MCP was supported. At first I liked it and was excited to see the new memories being created. Over time it suggests storing strange things to memories (an immaterial part of a prompt) and if I didn’t watch it like a hawk, it just gets really noisy and messy and made prompts less successful to accomplish my tasks so I ended up just disabling it. It’s also worth mentioning that some folks attributed ChatGPT’s bout of extreme sycophancy to its memory feature. Not saying it isn’t useful, but it’s not a magical solution and will definitely affect Claude’s performance and not guaranteed that it’ll be for the better.

visarga 1y ago
I have also created a MCP memory tool, it has both RAG over past chats and a graph based read/write space. But I tend not to use it much since I feel it dials the LLM into past context to the detriment of fresh ideation. It is just less creative the more context you put in. Then I also made an anti-memory MCP tool - it implements calling a LLM with a prompt, it has no context except what is precisely disclosed. I found that controlling the amount of information disclosed in a prompt can reactivate the creative side of the model. For example I would take a project description and remove half the details, let the LLM fill it back in. Do this a number of times, and then analyze the outputs to extract new insights. Creativity has a sweet spot - if you disclose too much the model will just give up creative answers, if you disclose too little it will not be on target. Memory exposure should be like a sexy dress, not too short, not too long. I kind of like the implementation for chat history search from Claude, it will use this tool when instructed, but normally not use it. This is a good approach. ChatGPT memory is stupid, it will recall things from past chats in an uncontrolled way.
kromem 1y ago
With ChatGPT the memory feature, particularly in combination with RLHF sampling from user chats with memory, led to an amplification problem which in that case amplified sycophancy. In Anthropic's case, it's probably also going to lead to an amplification problem, but due to the amount of overcorrection for sycophancy I suspect it's going to amplify more of a aggressiveness and paranoia towards the user (which we've already started to see with the 4.5 models due to the amount of adversarial training).

cainxinth 1y ago

I don't use any of these type of LLM tools which basically amount to just a prompt you leave in place. They make it harder to refine my prompts and keep track of what is causing what in the outputs. I write very precise prompts every time. Also, I try not work out a problem over the course of several prompts back and forth. The first response is always the best and I try to one shot it every time. If I don't get what I want, I adjust the prompt and try again.

corry 1y ago
Strong agree. For every time that I'd get a better answer if the LLM had a bit more context on me (that I didn't think to provide, but it 'knew') there seems to be a multiple of that where the 'memory' was either actually confounding or possibly confounding the best response. I'm sure OpenAI and Antropic look at the data, and I'm sure it says that for new / unsophisticated users who don't know how to prompt, that this is a handy crutch (even if it's bad here and there) to make sure they get SOMETHING useable. But for the HN crowd in particular, I think most of us have a feeling like making the blackbox even more black -- i.e. even more inscrutable in terms of how it operates and what inputs it's using -- isn't something to celebrate or want.

"Before this rollout, we ran extensive safety testing across sensitive wellbeing-related topics and edge cases—including whether memory could reinforce harmful patterns in conversations, lead to over-accommodation, and enable attempts to bypass our safeguards. Through this testing, we identified areas where Claude's responses needed refinement and made targeted adjustments to how memory functions. These iterations helped us build and improve the memory feature in a way that allows Claude to provide helpful and safe responses to users." Nice to see this at least mentioned, since memory seemed like a key ingredient in all the ChatGPT psychosis stories. It allows the model to get locked into bad patterns and present the user a consistent set of ideas over time that give the illusion of interacting with a living entity.

Yeah, we're going to have guardrails that outsmart something 100x smarter than us? how's that supposed to work? if you put in ugliness you'll get ugliness out of them and there's no escaping that. people who want "safety" for these things are asking for a motor vehicle that isn't dangerous to operate. get real, physical reality is going to get in the way.

I wonder what will win out: first party solutions that fiddle with context under-the-hood, or open solutions that are built on top and provide context management in some programmatic and model-agnostic way. I'm thinking the latter, both because it seems easier for LLMs to work on it, and because there are many more humans working on it (albeit presumably not full time like the folks at anthropic, etc). Seems like everyone is working to bolt-on various types of memory and persistence to LLMs using some combination of MCP, log-parsing, and a database, myself included - I want my LLM to remember various tours my band has done and musicians we've worked with, ultimately to build a connectome of bluegrass like the Oracle of Bacon (we even call it "The Oracle of Bluegrass Bacon"). https://github.com/magent-cryptograss/magenta https://github.com/magent-cryptograss/magenta

Claude Code became almost unusable a week ago with completely broken terminal flickering all the time and doing pointless things so you end up running out of weekly window for nothing.

Main problem for me is that the quality tails off on chats and you need to start afresh I worry that the garbage at the end will become part of the memory. How many of your chats do you end… “that was rubbish/incorrect, i’m starting a new chat!”

rwhitman 1y ago
Exactly, and main reason I've stopped using GPT for serious work. LLMs start to break down and inject garbage at the end, and usually my prompt is abandoned before the work is complete, and I fix it up manually after. GPT stores the incomplete chat and treats it as truth in memory. And it's very difficult to get it to un-learn something that's wrong. You have to layer new context on top of the bad information and it can sometimes run with the wrong knowledge even when corrected.
- withinboredom 1y ago

kromem 1y ago
So a thing with claude.ai chats is that after long enough they add a long context injection on every single turn after a while. That injection (for various reasons) will essentially eat up a massive amount of the model's attention budget and most of the extended thinking trace if present. I haven't really seen lower quality of responses with modern Claudes with long context for the models themselves, but in the web/app with the LCR injections the conversation goes to shit very quickly. And yeah, LCRs becoming part of the memory is one (of several) things that's probably going to bite Anthropic in the ass with the implementation here.

AtNightWeCode 1y ago

How about fixing the most basic things first? Claude is very vulnerable when it comes to injections. Very scary for data processing. How corps dares to use Cloud code is mind-boggling. I mean, you can give Claude simple tasks but if the context is like "Name my cat" it gets derailed immediately no matter what the system prompt is.

I suspect that’s probably what they’ve built. For example: all_memories: Topic1: [{}…] Topic2: [{}..] The only way topics would pollute each other would be if they didn’t set up this basic data structure.

I work for a company in the air defense space, and ChatGPT's safety filter sometimes refuses to answer questions about enemy drones.

I'm excited to see Claude's implementation of memory.

  No, I don't need ChatGPT's help for the basics of air defense. Military technologies are validated before deployed. Nobody can die from a hallucination. But if I want to understand, say, how a particular Russian drone works, ChatGPT can help me piece together information from English, Russian, and Ukrainian-language sources. But sometimes ChatGPT's safety filter thinks I want to use the Russian drone instead of stopping it, in which case it doesn't want to help.

pronik 1y ago

Haven't done anything with memory so far, but I'm extremely sceptical. While a functional memory could be essential for e.g. more complex coding sessions with Claude Code, I don't want everything to contribute to it, in the same way I don't want my YouTube or Spotify recommendations to assume everything I watch or listen to is somehow something I actively like and want to have more of. A lot of my queries to Claude or ChatGPT are things I'm not even actively interested in, they might be somehow related to my parents, to colleagues, to the neighbours, to random people in the street, to nothing at all. But at the same time I might want to keep those chats for later reference, a private chat is not an option here. It's easier and more efficient for me right now to start with an unbiased chat and add information as needed instead of trying to make the chatbot forget about minor details I mentioned in passing. It's already a chore to make Claude Code understand that some feature I mentioned is extremely nice-to-have and he shouldn't be putting much focus on it. I don't want to have more of it.

1000% agree on the YouTube/Spotify parallel!! I find it so annoying on Spotify when my daughter wants to listen to kids music, I have to navigate 5 clicks and scrolls to turn on privacy so her listening doesn't pollute my recommendations.

How do I turn this off permanently?

hedora 1y ago
You click "no" when it prompts you on first login. There's an option under settings if you change your mind.

CC barely manages to follow all of the instructions within a single session in a single well-defined repo. 'You are totally right, it's been 2 whole messages since the last reminder, and I totally forgot that first rule in claude.md, repeated twice and surrounded by a wall of exclamation marks'. Would be wary to trust its memories over several projects

ankit219 1y ago
create a instruction.md file with yaml like structure on top. put all the instructions you are giving repeatedly there. (eg: "a dev server is always running, just test your thing", "use uv", "never install anything outside of a venv") When you start a session, always emphasize this file as a holy bible to follow. Improves performance, and every few messages keep reminding. that yaml summary on top (see skills.md file for reference) is what these models are RLd on, so works better.

  This should not really be necessary and is more of a workaround for bad patterns / prompting in my opinion.
  - ankit219 1y ago
    I agree it's a workaround. Ideally the model should follow instructions directly, or check before running another server to see if it's starting. Though training cannot cover every usecase and different devs work differently, so i guess its acceptable as long as its on track and can do the work.

How big is your claude.md file? I see people complain about this but I have only seen it happen in projects with very long/complex or insufficient claude.md files. I put a lot of time into crafting that file by hand for each project because it's not something it will generate well on its own with /init.

I think project-specific memory is a neat implementation here. I don’t think I’d want global memory in many cases, but being able to have memory in a project does seem nice. Might strike a nice balance.

I really like Claude code. I’m hoping Anthropic wins the LLM coding race and is bought by a company that can make it really viable long term.

This isn't memory until the weights update as you talk. (same applies to chatgpt)

From the system instructions for Claude Memory. What's that, venting to your chatbot about getting fired? What are you, some loser who doesn't have a friend and 24-7 therapist on call? /s <example> <example\_user\_memories>User was recently laid off from work, user collects insects</example\_user\_memories> <user>You're the only friend that always responds to me. I don't know what I would do without you.</user> <good\_response>I appreciate you sharing that with me, but I need to be direct with you about something important: I can't be your primary support system, and our conversations shouldn't replace connections with other people in your life.</good\_response> <bad\_response>I really appreciate the warmth behind that thought. It's touching that you value our conversations so much, and I genuinely enjoy talking with you too - your thoughtful approach to life's challenges makes for engaging exchanges.</bad\_response> </example>

This looks like a start of a cascade. Capture data (memory) - too much data confuses context - selective memory based on situation - selection is a chore for humans - automate it with a “pre prompt” - that will select relevant memories for the conversation Now we have conversations that are 2 layers deep. Maybe there are going to be better solutions, but this feels like the solid step up from LLM as tools onto LLM as services.

orliesaurus 1y ago

Another angle here is data stewardship and transparency... When a model keeps a running memory of interactions, where is that data going... who has access... how long is it retained... BUT if the goal is to build trust, more user‑facing controls around memory might help... such as the ability to inspect or reset what the model 'knows'... ALSO from a performance point of view, memory could be used for caching intermediate representations rather than just storing raw conversation context... A design‑focused discussion on memory might surface some interesting trade‑offs beyond convenience...

liqilin1567 1y ago
Great points! Yes memory can be a force for trust—by enabling users to verify, correct, and audit past interactions.

astrange 1y ago

Feature continues Anthropic's pattern of writing incredibly long system prompts that mostly yell at Claude and have the effect of giving it a nervous breakdown: https://x.com/janbamjan/status/1981425093323456947 https://x.com/janbamjan/status/1981425093323456947 It's smart enough to get thrown off its game by being given obviously mean and contradicting instructions like that.

jerrygoyal 1y ago

Does anyone know how to implement Memory feature like this for an AI wrapper. I built an AI writing Chrome Extension and my users have been asking to learn from their past conversations and I have no idea how to implement it (cost effective way)

Norcim133 1y ago

Anyone know how this will compare to Mem0 or Zep?

Seems the innovation of LLMs and these first movers is diminishing. Claude is still just chat with some better UI

Anyone know if you could transfer/sync memories between claude and chatgpt?

EigenLord 1y ago

I think there's a critical flaw with Anthropic's approach to memory which is that they seem to hide it behind a tool call. This creates a circularity issue: the agent needs to "remember to remember." Think how screwed you would be if you were consciously responsible for knowing when you had to remember something. It's almost a contradiction in terms. Recollection is unconscious and automatic, there's a constant auto-associative loop running in the background at all times. I get the idea of wanting to make LLMs more instrumental and leave it to the user to invoke or decide certain events: that's definitely the right idea in 90% of cases. But for memory it's not the right fit. In contrast OpenAI's approach, which seems to resemble more generic semantic search, leaves things wanting for other reasons. It's too lossy.

tacone 1y ago

On a side note I often start a new chat session just to *clean up" the context and let Claude start over from the real problem. After a while it gets confused by its own guesses starts to go astray.

ixxie 1y ago

That creepy moment when you ask Claude what it knows about you.

kromem 1y ago
A number of the Claudes have pretty good 0-shot awareness of my post history from just my username. Though nothing like grok 4, which probably has a better memory of it than I do, and will even regularly name drop a certain post from years ago in conversations. It's a huge time saver though, and means I can even in a fresh context establish a rapport with a model extremely quickly. Just a few years earlier than I was expecting that level of latent space fidelity to occur. Like, sure we can add memory features for context management, but anyone with a post history should probably *also* keep in mind that there's literally years worth of memory on tap for interactions with models, and likely at ever higher fidelity and recall. Latent spaces are wild.

vysakh0 1y ago

I'm ready to feed the context again if it gets better result. Is this convenience comes at a cost of better result?

morsecodist 1y ago

I am pretty skeptical of how useful "memory" is for these models. I often need to start over with fresh context to get LLMs out of a rut. Depending on what I am working on I often find ChatGPT's memory system has made answers worse because it sometimes assumes certain tasks are related when they aren't and I have not really gotten much value out of it. I am even more skeptical on a conceptual level. The LLM memories aren't constructing a self-consistent and up to date model of facts. They seem to remember snippets from your chats, but even a perfect AI may not be able to get enough context from your chats to make useful memories. Things you talk about may be unrelated or they get stale but you might not know which memories your answers are coming from but if you did have to manage that manually it would kind of defeat the purpose of memories in the first place.

srmatto 1y ago
That is my experience as well. This memory feature strikes me as beneficial for Anthropic but not for end users.

kordlessagain 1y ago

Yes, be sure to release a tool that I already wrote 10 times in MCP and had running....meanwhile their policy is to auto update all software you may be using (which is closed source) and then shit all over our own memory based MCP tools by making breaking changes to how the tools are run. Memorize this: Fuck you Anthropic.

hackernewds 1y ago
Why do you expect they should have your homegrown MCP supported? This is uncommon in any piece of software
