Show HN: AI Timeline – 171 LLMs from Transformer (2017) to GPT-5.3 (2026)
Interactive timeline of every major Large Language Model. Filterable by open/closed source, searchable, 54 organizations tracked.
- YetAnotherNick 7mo agoIt misses almost every milestones, and lists Llama 3.1 as milestone. T5 was much bigger milestone than almost everything in the list.
- embedding-shape 7mo ago> T5 was much bigger milestone than almost everything in the list. It's in the timeline though? Or are you saying that one should somehow be highlighted, even though none of the other ones are? Seems it's just chronological order, with no one being more or less visible than others, as far as I can see.
- YetAnotherNick 7mo agoSome are highlighted and listed as milestones.
- ai_bot 7mo agoFair point on T5 — just marked it as a milestone. On Llama 3.1: it's there as a milestone because it was the first open model to match GPT-4 at 405B, which felt like a genuine inflection point. Happy to debate the milestone criteria though — what would you add?
- YetAnotherNick 7mo agoThat was llama 3, which is marked as milestone already. Also I would say add apple/DCLM-7B(not as milestone imo) as it was kind of the first fully open model which was at least somewhat competitive with closed data model.

- NitpickLawyer 7mo agoMisses a few interesting early models: GPT-J (by Eleuther, using gpt2 arch) was the first-ish model runnable on consumer hardware. I actually had a thing running for a while in prod with real users on this. And GPT-NeoX was their attempt to scale to gpt3 levels. It was 20b and was maybe the first glimpse that local models might someday be usable (although local at the time was questionable, quantisation wasn't as widely used, etc).
- ai_bot 7mo agoGreat catches — just added GPT-Neo (2.7B, Mar 2021), GPT-J (6B, Jun 2021), and GPT-NeoX (20B, Apr 2022). Thanks!
- pu_pe 7mo agoGPT-J was the one that made me really interested in LLMs, as I could run it on a 3090. Some details on the timeline are not quite precise, and would benefit from linking to a source so that everyone can verify it. For example, HyperClOVA is listed as 204B parameters, but it seems it used 560B parameters (https://aclanthology.org/2021.emnlp-main.274/ https://aclanthology.org/2021.emnlp-main.274/).
- ai_bot 7mo agoGreat idea! Thanks
- Maro 7mo agoThis would be interesting if each of them had a high-level picture of the NN, "to scale", perhaps color coding the components somehow. OnMouseScroll it would scroll through the models, and you could see the networks become deeper, wider, colors change, almost animated. That'd be cool.
- ai_bot 7mo agoThanks! Great idea
- jvillasante 7mo agoWhy is it hard in the times where AI itself can do it to add a light mode to those blacks websites!? There are people that just can't read dark mode!
- ai_bot 7mo agoThank you! Sorry for the inconvenience. I'll add it a bit later
- Lerc 7mo agoVisual presentation has been a weak point of AI generation for me. There isn't a lot of support for them seeing how a potential presentation might appear to a human. Models that take visual input seem more focused on identifying what is in the image compared to what a human might perceive is in an image, and most interfaces lack any form of automated feedback mechanism for them to look at what it has made. In short, I have made some fun things with AI but I still end up doing CSS by hand.
- varispeed 7mo agoThe models used for apps like Codex, are they designed to mimic human behaviour - as in they deliberately create errors in code that then you have to spend time debugging and fixing or it is natural flaw and that humans also do it is a coincidence? This keeps bothering me, why they need several iterations to arrive at correct solution instead of doing it first time. The prompts like "repeat solving it until it is correct" don't help.
- embedding-shape 7mo ago> as in they deliberately create errors in code that then you have to spend time debugging and fixing No, all the models are designed to be "helpful", but different companies see that as different things. If you're seeing the model deliberately creating errors so you have something to fix, then that sounds like something is fundamentally wrong in your prompt. Besides that, I'm guessing "repeat solving it until it is correct" is a concise version of your actual prompt, or is that verbatim what you prompt the model? If so, you need to give it more details to actually be able to execute something like that.
- koakuma-chan 7mo ago> If you're seeing the model deliberately creating errors so you have something to fix, then that sounds like something is fundamentally wrong in your prompt. No, all these models are just bad for anything that they weren't RLed for, and decent for things they were. Decent, because people who evaluate them aren't experts.
- embedding-shape 7mo ago> No, all these models are just bad for anything that they weren't RLed for, and decent for things they were Are you claiming that the models are RLed to intentionally adding errors to our programs when you use them, or what's the argument you're trying to make here? Otherwise I don't see how it's relevant to how I said.

- hmokiguess 7mo agoWould be nice to see some charts and perhaps an average of the cycles with a prediction of the next one based on it
- ai_bot 7mo agoThanks! I'll add some charts
- EpicIvo 7mo agoGreat site! I noticed a minor visual glitch where the tooltips seem to be rendering below their container on the z-axis, possibly getting clipped or hidden.
- ai_bot 7mo agoThanks for the feedback! I'll fix it asap.
- adt 7mo ago750+ here: https://lifearchitect.ai/models-table/ https://lifearchitect.ai/models-table/
- ai_bot 7mo agoGreat resource — Dr. Thompson's table is exhaustive. llm-timeline.com takes a different angle: visual timeline format, focused on base/foundation models only, filterable by open/closed source. Different tools for different needs.

- wobblywobbegong 7mo agoCalling this "The complete history of AI" seems wrong. LLM's are not all AI there is, and it has existed for way longer than people realize.
- nubg 7mo agoMost of "AI" before ChatGPT was just researchers wasting public grant money, eg BLOOM.
- gordonhart 7mo agoEasy to forget but there was a ton of industry+investor excitement around computer vision from ~2015-2021, to the extent that the "MLops" niche sprung up around it. This was called AI at the time, and mostly went out the window when general-pupose pretrained models arrived.
- stuxnet79 7mo agoI would place the beginning of the computer vision hype at 2012 or so when the AlexNet paper came out. Also an aside, it is mind boggling to me how pre-2021 ML is now ancient history.
- bigstrat2003 7mo agoAnd now it's private companies wasting investor money. Not sure there's much difference between the two.
- _verandaguy 7mo agoThis is ignoring ML which has existed for decades. Neural networks, computer vision, sentiment analysis, all of these and more have provided an unspeakable amount of value over the years.
- ai_bot 7mo agoFair point — updated the tagline to 'The complete history of LLMs'. AI as a field goes back decades; this is specifically tracking the transformer/LLM era from 2017 onward
- jcims 7mo agoI was born in 1973. My grandson was born in 2022. He won't know a world without 'AI' much like my kids didn't know a world without the Internet and I didn't know a world without refrigerators. One thing I regret to say that I learned very late in my children's development was the value of boredom and difficult challenges. However I think I've successfully passed these lessons on to my kids as they raise their own. I have no idea what to say about 'AI' and the rapid reconfiguration of our relationship with the world that's going to happen as a result. All I can tell them is that we're in this together and we'll try to figure it out as we go. Good luck everybody!
- roegerle 7mo agoI feel so old now
- NoOn3 7mo agoYou know a world without refrigerators? :)
- tadfisher 7mo agoI would think your parents thought about television more than refrigerators. That's one technology that really set the world on a new trajectory. Imagine if Nixon won the presidency in 1960, if we didn't have real-time video of the Apollo landings, or if America stayed in Vietnam for another ten years.
- HPsquared 7mo agoTelevision and radio set the parameters for the "single-stream culture" that emerged in the 20th century. Mostly a result of the limited bandwidth of early broadcast technology, so everyone had to watch the same few channels. Web 2.0 broke this into millions of creators. Generative AI produces everything on-demand, but again there is a small number of (polymorphic) models producing the content.
- fergal_reid 7mo agoMy story of kids growing up in a post AI world: There's a gag in Star Trek 4 where Scotty goes back in time, and tries talk to a computer. The gag is funny because he is from the future where you talk to computers normally. When the computer doesn't respond, someone hands him the mouse, and he tries use it as a microphone. I watched that scene with my kids recently (9 and 6). They didn't get the gag. They thought Scotty was completely reasonable to try and talk to the computer. It took a while to explain.
- badsectoracula 7mo agoInteresting site, though it does seem to miss some of Mistral's stuff - specifically, Mistral Small 3 which was released under Apache 2.0 (which AFAIK was the first in the Mistral Small series to use a fully open license - previous Mistral Small releases were under their own non-commercial research license) and its derivatives (e.g. Devstral -aka Devstral Small 1- which is derived from Mistral Small 3.1). It is also missing Devstral 2 (which is not really open source but more of a "MIT unless you have lot of money") and Devstral Small 2 (which is under Apache 2.0 and the successor to Devstral [Small] - and interestingly also derived from Mistral Small 3.1 instead of 3.2).
- ai_bot 7mo agoGood catches — just added Devstral Small 1 (May 2025, Apache 2.0), Devstral 2 (Dec 2025, modified MIT), and Devstral Small 2 (Dec 2025, Apache 2.0). Thanks for the feedback!
- Panoramix 7mo agoNice overview. Some of the descriptions are quite thin on details, like "new model by x", or "latest model by y". Well of course it was new at the time but that doesn't really add information.
- Sajarin 7mo agoShameless plug but made a similar tree here: https://sajarin.com/blog/modeltree/ https://sajarin.com/blog/modeltree/
- l-p 7mo agoThanks, that's way more useful to me. Allow me to contribute: > Magistral: Magist(rate) + stral? Mag(nificent) + stral? Nobody knows. That's just French for "masterful" or a way to describe lectures. There's a sense of greatness in that word that contrasts with the Mini in Ministral which is in turn might be a pun on "ménestrel" (minstrel), "ministre" (minister), or made to sound like Minitel (or all of the above).
- j_bum 7mo agoThis is great, I found it much more interesting to view this tree vs. the timeline alone.
- youngprogrammer 7mo agoshould go a bit earlier with word2vec, NMT, seq2seq, attention, self attention
- Perenti 7mo agoIt would be nice if clicking on a list entry (say llama3 ) opened a window/tab on the home page of that model.
- umairnadeem123 7mo ago[dead]
- anshumankmr 7mo agoCould have some more of the Sarvam models, including the ones recently announced.. But happy to see their names mentioned. Had tried joining them but they ghosted after one round :(
- naillang 7mo ago[dead]
- piinbinary 7mo agoI think it's missing Google's Bard
- johntheagent 7mo ago[dead]
- das-bikash-dev 7mo agoInteresting to see the evolution mapped out like this. For those building on top of these models (RAG systems, agent frameworks), the real inflection point wasn't just model count but the shift from completion-only to reasoning and structured output capabilities. Are you planning to add annotations for capability changes alongside release dates?
