DeepSeek reasonix, DeepSeek native coding agent with high caching and low cost

• embedding-shape 5mo ago
  I'm not sure you need a "DeepSeek native coding agent" to take advantage of DeepSeeks cache, yesterday as the Codex quota usage issue still wasn't solved for me, I wrote a tiny little bridge so I could use DeepSeek V4 Pro via Codex, and seems most of everything I did was basically cached as far as I can tell: https://i.imgur.com/7eKn6wN.png https://i.imgur.com/7eKn6wN.png (2026-05-23 Input (Cache hit): 39,123,200 tokens, Input (Cache miss) 1,692,286), and the bridge is doing not special, just massage the DeepSeek API shape into what Codex expects, nothing particular about caching at all. Besides being even better at the caching, I'm not sure what benefits you'd get compared to just firing up OpenCode with the DeepSeek API yourself, it'll similarly do caching for sure and also "talks directly to api.deepseek.com" if that matters, and you'll get a much more mature harness.

    > I wrote a tiny little bridge so I could use DeepSeek V4 Pro via Codex Can you share the bridge. DeepSeek v4 is awesome paired with claude-code or opencode. I found that claude code costs me less than opencode and I am presuming this is due to a better engineered harness.
    • embedding-shape 5mo ago
      Sure, keep in mind it's a steaming pile of hacked together hacks, probably won't work in every case, doesn't support every feature that should be supported (like parallel tool calling, both Codex + DeepSeek API support it), and it might make your computer catch on fire: https://gist.github.com/embedding-shapes/eab3e63e5a95d3d78a270472e1be0c9e https://gist.github.com/embedding-shapes/eab3e63e5a95d3d78a2... I only used it for a few hours to play around with stuff before the quota issue was fixed and I could resume using GPT models, and the bridge was coded by DeepSeek-V4-Flash-IQ2XXS + DwarfStar4 locally, I take no responsibility for what might happen with your computer or you, during usage or just reading the code. Edit: heh, like don't look at line 117 for example where seemingly it likes to handle misspellings in the .env file which totally wasn't my fault for typo'ing the API key in that file... I'm sure there are tons of sharp edges and dumb stuff in there.

      I’m feeling more a novice every day, but how isn’t this just handing over your code to team deepseek for whatever they might want
      • embedding-shape 5mo ago
        Not everyone is working with state secrets or user personal data (or even more closely guarded, company secrets) on a daily basis, most of what I hack on is either FOSS already, or will be, not much to keep secret here. Obviously, if you do deal with any sort of secrets, then using local LLMs over OpenAI, Anthropic, DeepSeek or whoever is obviously preferred, and in the case of personal data of users, probably a requirement.
        • jack_pp 5mo ago
          either this or you work on software that even if copied won't get you far since the business relies on network effects or pure networking. Getting the source code of facebook or instagram doesn't mean you could compete with them. I work for a company that has built relationship with event organizers over the past 10 years. The code I maintain could be written from scratch in maybe 2-3 months even though it was built over the past 10 years but besides that you have frontend / DB / hardware / logistics etc
          • Demiurge 5mo ago
            I actually agree with you, for the most part. The code I work with actually does contain some valuable algorithms, but Im pretty sure the effort of integrating them into a larger system is pointless without the data. It’s almost like stealing half-life 2 source code without any assets. Still, “Getting the source code of facebook or instagram doesn't mean you could compete with them.” I think to giants like that, having access to their source code could open up some very interesting loop holes for manipulating the ranking algorithms, or even security vulnerabilities.

    • spacedcowboy 5mo ago
      I don't think DeepSeek v4 Flash is as good as Claude for relatively complex tasks. I ran with DeepSeek for a week, giving it the same sort of tasks that Claude normally does, and then ran Claude and asked it to continue. It found a whole bunch of things that had been "overlooked" by DeepSeek, and spent some time fixing them before wanting to move on. DeepSeek is good, Claude is better, at least IMHO. Deepseek is a lot cheaper though :)

    this appears to be native to the terminal, as in, there's no special application that runs or wraps an agent inside a tui. So basically instead of commands you type plain english?
    • embedding-shape 5mo ago
      > this appears to be native to the terminal, as in, there's no special application that runs or wraps an agent inside a tui Same with codex? codex-rs at least, is a TUI as well, it does run a "app-server" in the background, that the TUI actually interacts with, but that's just an implementation detail. Also makes it easy to hook in your own programs to fire of codex "headless" sessions even without the TUI.

    Opencode has really bad cache stability issues that they seem uninterested in fixing at the moment.

          > Ah, reminds me of good old "There are only 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors." You quip, but LLM KV caching (from the harness side) is quite easy: You get a cache hit on stable prompt prefixes, period. That means you want to keep the prefix stable, and only append at the end of the conversation. Made up example: Don't put the git branch name into the system prompt part (that comes first), as whenever the branch name changes, that'd trigger a cache invalidation of the entire prompt. Getting this right requires some care to not by accident modify the prefix, basically, and some design on communicating the things that can change (user configuration, working dir, git information, ...).

            That sounds like the experience of writing Containerfiles; since steps are cached you want to pull the thing you are iterating on as far down as possible.
  • kiproping 5mo ago
    This would be a better page to link to https://github.com/esengine/DeepSeek-Reasonix/blob/main/docs/ARCHITECTURE.md#pillar-1--cache-first-loop https://github.com/esengine/DeepSeek-Reasonix/blob/main/docs... They explain some of the the reasons why they have a better solution and why they are very opinionated >Automatic prefix caching activates only when the exact byte prefix of the previous request matches. Most agent loops reorder, rewrite, or inject fresh timestamps each turn — cache hit rate in practice: <20%. So they optimize on this plus other techniques to improve cache hits, making it cheaper.
    • krackers 5mo ago
      >Most agent loops reorder, rewrite, or inject fresh timestamps each turn That's really surprising, since it'd defeat the whole point of KV caching. I mean I buy it considering how sloppily coded the harnesses seem to be, but this like obvious low hanging fruit. I've also often wondered why LLMs aren't trained with a format of having a dedicated contextual system-instruction role at the _end_, which you could use to put context like current time or other misc stuff.
      • jeremyjh 5mo ago
        Its not surprising, that doc is full of AI slop.
      • benjamincburns 5mo ago
        I don't think it's factually correct. There are context pruning strategies that will prune old messages that are no longer relevant, and context compaction from summaries, etc. But to say "most" do this on "every turn" is overstating things. I think it's more correct to say that "many" do this "occasionally." I'm also not sure what they mean about injecting fresh timestamps. I could see why you'd prepend/append a timestamp to the user's messages to make the model aware of the current time, and the passage of time, but I can't think of any good reason to edit timestamps in prior messages. I'm sure someone can come up with one, but I'd be very surprised if this was a thing that most agent loops do, let along doing it on every turn.

  So what's best low cost coding agent these days? Kimi 2.6? Qwen's latest closed model? Composer 2.5? DeepSeek?
  • bwfan123 5mo ago
    In my experience, it is claude-code paired with deepseek-v4. For penny-pinchers like me, I can have long coding sessions with it with no anxiety about the cost. Also, prompting it to what you want and verifying the outputs is more important than the quality of the model. So, I am better off with a cheaper model and taking the responsibility for prompting it and verifying the results.
    • epolanski 5mo ago
      Can you quantify the actual costs in a week and the use you make?
      • wongarsu 5mo ago
        Not GP, but for my use I'd estimate $0.10-0.30 per hour of use per agent with DeepSeek v4 Pro

• theanonymousone 5mo ago
  Isn't caching a server-side thing? How does the agent affect it, significantly at least?
  • embedding-shape 5mo ago
    Say you put the current time down to the second in the system prompt, which is the message that goes in front of the entire conversation, then basically nothing will be cached, every agent turn needs to ingest the entire session over and over. Contrast to not doing that, and the backend can leverage caching all the way up to the latest message, as nothing until then changed.
    • esperent 5mo ago
      Surely other agent CLIs are not dumb enough to invalidate cache on every turn over something so obvious?
      • embedding-shape 5mo ago
        Obviously not, most agents properly keep previous messages unchanged, at least the major ones I've been digging into the source off. Also, everything would get so much slower, that even developers creating their own agents would notice quickly how much slower theirs is, if they fuck this up.
      • chillfox 5mo ago
        I don't think any the agents breaks caching on every turn, but they might do things like current list of files, or available tools depending upon plan/build mode... or lots of other things that breaks caching multiple times during a session.
      • brookst 5mo ago
        Probably not that exactly, but there is a tradeoff between effectiveness of the prompt and cache hit rate. If putting the user’s datetime in the middle of the prompt scores higher on evals but worsens cache hits, versus at the end of the prompt where it’s cache friendly but may not be as effective, what do you do? This is still art as much as science and the different harnesses take different approaches.
• declan_roberts 5mo ago
  I love the focus on cache hit efficiency. Hats off to the deekseek team for creating a great product that maximizes cost efficiency for the user.
  • bwfan123 5mo ago
    > Hats off to the deekseek team for creating a great product I have been using it for a while, and I wholeheartedly agree. imo, it is as good as codex or claude which I also use. It is a winner in the cost-sensitive tier, and if some startup could put it together with data-retention in mind, it could be a great product sold to the enterprise, as data-retention and privacy are the main issues for the coding-assistant usecase.
    • chillfox 5mo ago
      Deepseek v4 pro is definitely my preferred cheap model, it's very good, and I use it all the time for my personal projects (opencode go plan), but I also use Claude Opus all the time at work and Deepseek is not as good as that, but it does compete with Sonnet for capability, and beats it on price.
      • pjerem 5mo ago
        I have unlimited Claude Opus at work and it’s wonderful. Not allozwed to use it for personal use though. So I use Deepseek Pro on the $20 Ollama Cloud plan and it’s really not that far behind and I never triggered the plan’s limits. It’s like 10-15% less powerful but costs 10 times less. Totally worth it. I prefer Opus because my employer pays for it but I would personally never pay 10 times more for it.
        • chillfox 5mo ago
          Nice, I have got unlimited Claude Opus at work as well. I was really having a hard time deciding between the Ollama and OpenCode plans for personal use, I couldn't really understand how much usage I would get with the Ollama plan, so in the end I went with OpenCode and I have never hit the limits despite using it most evenings and weekends for several hours.
• sergiotapia 5mo ago
  What AI model did you use for the website design? This is the second one I see with the exact same font and color scheme. Just curious because Claude models lean towards purples for example. Thank you!
  • pcwelder 5mo ago
    Opus 4.7 selects such palette and motifs by default. Might even be first iteration of claude design.
  • franga2000 5mo ago
    This design still screams Claude to me, but a newer version than what you're thinking of. At some point they added a markdown file that tells it to use obviously AI designs like lots of blue/purple and gradients. Since then, this is its new style.

  Okay, I'm curious. From the FAQ, I see: >Can I point it at a self-hosted / private DeepSeek endpoint? >Yes. Since 0.30 we accept non-standard key prefixes for self-hosted DeepSeek endpoints. Just point `baseUrl` at your internal address — the loop, cache strategy, and tool protocol are unchanged. But my question is: If I use Reasonix to talk to a deepseek endpoint through openrouter, am I still getting the cache-hit benifits of this agent harness?
  • csunoser 5mo ago
    Yes*. At least from my limited usage of deepseek-flash for a few billion tokens on openrouter, the cache-hit rate is >95%. And I simply used the claude code harness pointed at the openrouter anthropic compatible endpoint with no fluff.
    • schaefer 5mo ago
      thank you!
    • port11 5mo ago
      Did you get proper tool use? Some CC-driven models seem to get a bit off when it comes to MCP usage. For example: I really struggled to get Kimi to use Serena, which I think ended up costing too many tokens.
  • thomasfromcdnjs 5mo ago
    I would wonder that too, I'm only a novice openrouter user, but I do notice it reroutes my same-model requests to different providers. Maybe users reporting otherwise are just looking at their client reports which wouldn't be able to tell the difference.

  It's pretty funny, i'm a $200/m Claude subscriber and i've had little need to use anything else. However the more Claude has been restricting my workflow (notably around the recent IDE/-p usage change) the more i've been wanting to go elsehwere. I'm concerned since i really want SOTA reasoning, but DeepSeek still has me interested.
  • logicchains 5mo ago
    If you want SOTA reasoning you should be using GPT 5.5 Pro.
    • auggierose 5mo ago
      Codex has only GPT 5.5
    • unshavedyak 5mo ago
      This is fair, but i've found the different models to have different moods and require different interactions to get them to stick to just the specific edits i ask for, etc. I used to surf the three big players frequently and got really tired of the effort needed to steer some models. In the end i ended up sticking with Claude because it required less steering effort. While not strictly reasoning, a models ability to follow clear directions consistently is something i'd consider part of its SOTA capabilities. Eventually i just tired of exploring. I just want stability. Which ironically is why i'm thinking about moving from Claude. The very basic IDE/-p usage getting removed from my plan is a UX stability issue. I'm trying to progressively improve my workflows and efficiency, not have to establish a new foundation anytime something shifts. Quite frustrating.
  • Alifatisk 5mo ago
    > I'm concerned since i really want SOTA reasoning I think you should give other models a try and see how much they differ from SOTA models. I did this and realized, even Qwen-2.5-Max was enough.

  > no reordering, no marker-based compaction Is this really the behavior you want? Yes, doing tool-result clearing and such will blow your cache, but if you do it only occasionally, it's still likely a win. Yes, cache hits are good, but not so good that it's okay to be profligate with context to preserve those precious, precious KVs.
• yalogin 5mo ago

  > The loop is append-only, engineered around DeepSeek's byte-stable prefix cache — long sessions hold 90%+ cache hit and input-token cost collapses to ~1/5. Terminal-first, leave it running. AI marketing slop. This is how all models and coding harnesses work, isn't it? The author claims (in another AI-written post): > LangChain — along with every generic agent framework I checked — rebuilds the prompt every turn. Timestamps get injected. History gets reordered. Tool schemas re-serialize with different whitespace. I haven't touched LangChain in a long, long time, but don't think any of the current harnesses, Claude Code, Pi, Crush, OpenCode etc do that except if you change configuration? Keeping the context stable for caching is a very basic principle and not a wild innovation. This posing as DeepSeek-specific is also a mystery.

• fouric 5mo ago
  I don't think it's particularly effective to create a new coding agent when there's existing open-source agents (especially extremely extensible ones like Pi) that already optimize for cache hits, have far larger communities, and work for providers other than Deepseek. I specifically use multiple different models and providers, so this wouldn't be useful for me. And it contributes to the problem of each person vibe-coding their own, incompatible, half-baked tool in a space, instead of contributing to a small set of tools and expanding them. It'd be better to just extend an existing tool.

        I see your point, but as we know, devs from Google and OpenAI regularly use Claude Code because of its edge in frontend. I think using another model to build your own thing is a pragmatic engineering decision, not a sign of failure.

  Can it instruct DeepSeek during an LLM call to start removing old tool calls from the context instead of waiting for the LLM call to finish if the context size approaches DeepSeek's dumb zone? Claude Code can't do that, /compact can only happen after the LLM call; it's often preferable to start cleaning up context during an LLM call, especially when tool calls are huge like reading markdown files; implementation-wise all that is needed is to start removing earliest <tool call start> ... <tool call end> and replacing them just with some log entry stating this tool call was already performed, then re-running KV cache prefill (so the "online" compaction would get 0.5s latency hit every time it's performed). That way one can read 1000 files in one LLM call.

  > Tool-call repair > Tool arguments the model produces occasionally have JSON typos, unclosed quotes, or shape mismatches. Reasonix runs a schema-aware repair pass before dispatch so malformed args still execute. So Deepseek API doesn't have a structured output option where you give a grammar and the model promises the output will follow this grammar? Or it does, but it's buggy?

    Deepseek API caches very efficiently itself. I use it heavily via pi agent, and a lot of times I get 99%+ caching for longer sessions. Have you tried using Deepseek API via other agents? This project tbh looks like a S-tier slop

  This website seems to have been generated by Codex - I asked Codex to create an HTML overview of a feature for my team and it made an overly produced monstrosity - complete with the same large stat boxes that were for the most part devoid of meaningful information - using the same font, colors, layout, hero section, etc. It was also terrible on mobile just like this is. In the end I had Claude produce a one-page html file that was 95% of the way there and it took minor editing to clearly explain the intent of the feature.

    > In the end I had Claude produce a one-page html file that was 95% of the way there and it took minor editing to clearly explain the intent of the feature. That doesn't say much about any model though. For starters, any software engineer can tell you that leaving out features can drastically simplify any project.

    A lot of LLM-driven design now looks like this. I don’t understand how people don’t find ugly the pairings with an heavily italicised serif. You also can’t read much of the page on mobile, because the code example keeps shifting the content around. Now, that is overly critical, I’m sure their heart is in the right place. But a simpler website would do :)
    • krm01 5mo ago
      It’s sad to see companies not spending a bit more on design. Sure, ai will help you get something decent out fast. But there’s a threshold where design becomes an indicator of trust. Especially for b2b software that tailor to large corps. Good design, character, adds directly to the bottom line.

        > It’s sad to see companies… The article is about an open source agent harness, Reasonix, that is built to leverage the DeepSeek native api. There’s no company here. No design budget. These people are graciously sharing a project they made in their free time.

  i cant find anything substantiated in the code that actually differentiates it from any other harness. my fork of oh my pi that i have a lot of experiments in, is lterally designed to only work well with models that have decent reasoning levels, like deep seek models. check it out! https://github.com/cartazio/oh-punkin-pi/blob/main/scripts/build-binary.sh https://github.com/cartazio/oh-punkin-pi/blob/main/scripts/b... — thats the install script for after clone fair warning: tis my dog food test bed as i build even fancier stuff

  There is an uncanny valley effect to websites where FE is created in full via an AI. These sites have the immediate scent of 'high design', with errors that no 'high designer' would dare make. The italics give me nausea. Text promoted with orange fill is seemingly random. There is no thought behind the combination of art and copy. Random smattering of Title Case and Sentence case and lower case. A lack of commitment to a full stop Widowed H1s. H1s with random spaces . At the same time, if I hammer CMD - to 25%, it looks fancy. Perhaps nobody gives a fuck. That said, I'm excited to try this tool!

    I'm really happy to see a lot of new software come out in Rust, Go, or Zig. The value and ease of development that slow interpreted languages used to offer is disappearing. New languages have all the nice things built in, or rather, our 1am pager alarms are starting to make us mad.
  • crystal_revenge 5mo ago
    If this is what you want, especially in the age of coding agents, why not just build it yourself?
  • wg0 5mo ago
    Can someone explain that was use of AI (and all the claims) that a coding agent cannot be written in plain go for example? Given there are tons of good terminal libraries for golang?
    • xlii 5mo ago
      It can be written in Golang but interaction libraries are very limited and with sharp edges. There's Google's genkit, charmbracelet's fantasy and LangChainGo. Each has ugly hacks and omissions. Then handling slice streaming of data into Elm architecture (bubbletea) is also complex. So in theory nothing stand against but in practice one has to get quite low to the ground to get anything done. Also: Golang agent exist! It's called crush and is developed by charmbracelet people. It's so-so though I prefer Pi myself.
• jbellis 5mo ago
  As someone who has been writing harnesses for a year: the people at opencode etc aren't stupid, when they decide to break the prefix cache [usually partially] it's always because they've tested it and it gives better results overall. If you think that dsv4 behaves differently enough from the aggregate of other models, submit a PR with a patch to special case that to your harness of choice with evidence. Just blindly assuming "append only all the time because cache" is a waste of everyone's time.

    Are there any learning resources you'd recommend on writing harnesses? I'm interested in doing a non-coding one, but not really sure where to start.
    • jbellis 5mo ago
      Generically, I would say, just start building it and ask your favorite coding agent for advice when you get stuck. This is the first technology that can teach you how to use it! (But do ask a model with a recent knowledge cutoff, i.e. not gemini.)
    • sams99 5mo ago
      My agent wrote a pile of very interesting articles at wasnotwas.com I have been a bit quiet there for a bit, but it covers lots of areas that are very interesting to harness builders (albeit less interesting to the general public)

  I tried it and the text input area was black with a dark font. I checked the documentation, and asked DeepSeek v4, Claude, and Gemini for help with the fonts/style and nothing works except to run in a terminal with a dark theme. Crazy. None of the devs on the project use a light theme?
  • miav 5mo ago
    I agree that this is an issue, but.. no, they probably don’t. Light themes are very rarely used.
    • jofzar 5mo ago
      I understand why, but I didn't even think of light themed terminals till now.. .
• jedisct1 5mo ago
  It's probably good, and the best for Deepseek models, but do we really need one harness per model?
• nikolay 5mo ago
  This is not an agent by DeepSeek, so the title is misleading.
• trollbridge 5mo ago
  Well folks here we have it: DeepSeek’s brand is now strong enough people want to jump on their brand recognition.

  Side note: In DeepSeek API docs they mention that coding clients automatically are assigned the highest thinking effort, despite any settings. This is what I suspected when using OpenCode with V4; it keeps reasoning in very long cycles, this felt like a flaw in the model. May just be a weird API thing. Overall I find their API design and docs so messy. It's a shame, since it's the main entrypoint to using their service.
• tw1984 5mo ago
  deepseek is building an official coding harness, why would anyone waste time on such 3rd party toy when official one is coming probably in weeks?

  I don't think it's helpful, you can already get a 99+% cache hit on claude code, just change the api settings to deepseek. I would like to use a agent built by deepseek itself using deepseek models. Deepseek should make their own agent based on their model, just like OpenAI and Anthropic.
  • m00dy 5mo ago
    same here, using claude code on deepseekv4. just burnt 24.1M input hit and 170k cache miss.

  The prevalence of chinese training datasets has likely biased the model incorrectly. The model is still intelligent enough to flag this as a gap in its own abilities. Here is an example of Reasonix resuming a feature in a project managed by Codex thus far. > ● reasoning · 107 tok · 2 ¶ · 3.2s v4-flash ↳ The search engine is still completely broken - returning Chinese dictionary entries, Kick streamer profiles,… c. It's not just broken for ** content, it's broken for everything. The error from earlier said to switch … ⋯ 2 lines elided I need to be honest with the user that `web_search` is fundamentally non-functional regardless of what query I try. Let me clearly communicate this and suggest alternatives. ‹ reply 198 tok · 92 t/s v4-flash I'm sorry — I've now tried multiple queries across multiple attempts this session, and the web_search tool is fundamentally broken regardless of query phrasing. Every single query returns either Chinese dictionary entries, Kick streamers, YouTube homepages, or Swiss restaurants. Nothing even remotely related to the search terms. The error message from the tool itself says: "switch engine with /search-engine bing|searxng|metaso|tavily|perplexity|exa" This is a user-side setting — I can't change it with any tool I have. Could you run this in chat? /search-engine bing That would switch from the current broken Chinese-language engine to Bing (or one of the others like perplexity ). Once that's done, I'll batch-search all 322 centers efficiently — the web_search tool is the fastest way to do this since I can search multiple names in parallel.
