开源模型现状：Kimi K3、Qwen 3.8、WAIC演讲等

Exciting news! My book trying to share post-training knowledge with the world is done and shipping soon. Order on Manning or Amazon. Thanks for the support. It’s currently the #1 AI book on Amazon :).Nathan and Florian sit down to discuss everything happening with open models. Following the Kimi K3 release last week, it feels like everything is accelerating — geopolitics of US v China, economics of open vs. closed models, security at the frontier of AI, and so on.Chapters:00:00 Welcome & context04:38 Living with / using Kimi K308:53 GLM 5.2’s continued role12:47 How are the Chinese models this good?17:41 Data, environments, and a tour of the Chinese labs19:47 Roundup of Chinese providers: Qwen, DeepSeek, MiniMax…24:08 The US open-model ecosystem30:25 Frontier vs. near-frontier, and the cybersecurity case against bans34:58 Distillation and the Ben Thompson debate44:12 Predictions and a frontier tier list48:36 Wrap-upListen on Apple Podcasts, Spotify, and where ever you get your podcasts.

We’re doing our quarterly open model roundup, which is mostly us just making fun of or explaining, not making fun, why so many distillation takes are bad and understanding the state of where things stand. I think last Thursday was when Kimi K3 was released. I think we will see much much more in the near future. It seems pretty inevitable. Like over the weekend, Xi gave his speech where he directly committed to openness and open source as a strategy. It wasn’t a detailed layout state of affairs.Qwen announced their next big model is going to be open weight, which is a big change of things. I think there’s just so much to get into. I think Flo you kind of were already going off on some of the performance gap and distillation takes. So we could probably start there and then as I go I have a little bit a little list and we could always go through the topics and the blog that I wrote which all are very nuanced. So I think we have infinite to talk about. So continue rant kind.00:01:17 Florian Brand: Yeah, I think, or the biggest thing at every model release at least at every open model release is how much or how many months it is behind the closed frontier. Um and people love to put a definite uh definitive number onto this uh which is really really mudding because we have so many different benchmark providers these days and such uh so many different benchmarks as well that every site and I’m not innocent in that either um pulls up their favorite benchmarks to show that the current model or the newly released model is at the frontier which is then counted by the other side pulling up another benchmark and showing oh it’s actually a year behind or something. Um and it like a lot of it seemingly hinges on that question how many months we open models are behind.00:02:26 Nathan Lambert: Yeah. So I my provocation is that some of the benchmarks are actually reasonably correlated with what people are doing and this is agentic coding and agentic computer use tasks and some of the benchmarks are correlated with the long tail which is where I think Claude and GPT is so valuable. But if it’s it’s like what is the market for Claude Code and Codex right now and if it is software engineering then like the fact that the models are say a couple months behind on that can be a very, very big deal and then I suspect that this model will be okay disclaimer the model weights aren’t out yet supposedly on 20 July 27th and a lot of the discussion will impinge on the assumption that they come.But like people could post-train this model to very likely match Opus and GPT in many of these kind of niche domains that people want I think watching I mean we both have different views into the post-training open model industry, but there is a ton ton of excitement in progress on making these models like fine-tuned for specific high-value tasks and this has been historically done on a mix of like Qwen and GLM and GLM 5.2 really accelerated this and I I curious on the first person that puts out a blog post like we fine-tuned Kimi K3 on our task because I bet you could get big gains. I think even the you use Kimi K3 more than I do, but my hunch is that it would be a bit of a um rough edged post-training just by how big of a scale up it is and that normally means there’s a lot of performance that could still be extracted from it. No.00:04:03 Florian Brand: Yeah. Running, running, running and especially post-training that one will be super hard because you need like one node of B300s to just load the weights which is crazy in terms of scale. So will probably take some time and uh a lot of engineering I’ve heard to actually get this into a state where it’s fine-tunable. Um but people you want to talk about using the model like you actually signed up for the the coding program and used it. So like getting this out there is good context.00:04:38 Nathan Lambert: Yeah. So I signed up on day after release or so uh for the $200 plan uh which is their biggest one similar to to all the others but they have um like I think $40 and $100 as well. Uh but the biggest plan has uh 1 million context and I think or at least it feels like it has also some priority in terms of the API requests because so many people um online are saying that they hit API errors constantly and so far I’ve been I’ve been uh pretty well off if I’m uh going to say that. Um and in terms of model capabilities, it at some ways aside from front end where it is really good, it in some ways it really shines and it excels.Um even my um expectations even with things like uh some research tasks like I have or at interconnects we now have over a year of data on on open models um and I ask the frontier models to come up with some interesting analysis which we haven’t done before in uh because we do our own analysis and have this published uh and I asked them all right do something new and um surprise me, basically. And a lot of the models or the frontier models u or basically all models latch onto the things we’ve done redo the data analysis part and then do some weird esoteric parts.Uh Kimi K3 did some more interesting things um I’ve told it explicitly to scrape Reddit um and then it found uh some subreddits I haven’t even considered and then found out for example that the Reddit discussions are um one or two months in uh more recent or they found they find the interesting models one or two months before the download numbers usually take off like they are all onto Qwen and then the people download more Qwen models like those kind of analysis is groundbreaking um but it is something that Kimi surprised me at compared to to all the other frontier um models.A simple question like can you use this for most of the core work you do in terms of like the exp you you have a distribution of stuff you tend to do most of them are with Codex I think you’re a Codex person rather than Claude person like what percentage do you think the Venn diagram overlaps where this model would be fine00:07:24 Florian Brand: uh it’s really depends on how much leeway I give it like, the big thing I have seen with Kimi K3 right now I’m I’m working on u the framework we are doing at uh at Prime Intellect, where I work, and the main thing I found with Kimi is its code is a lot simpler uh which makes it way more readable uh but it misses some things that Codex just or like we’re talking 56, 55 and especially 54 would be on those levels. So, I would say that Kimi K3 is like 54-55 level for these kind of tasks.But if I like I read the code and I say all right that’s really good code and then I give it a pass over with with Codex and it finds all these niche niche cases where it doesn’t excel but for supervising runs or for running uh some experiments it is actually really usable. Um and for some othe
