The open-weight model ecosystem is maturing rapidly, with Kimi K3 rivaling frontier models and prompting a major industry letter arguing against US bans on open-weight AI.
Kimi K3, an open-weight model from Moonshot AI, matches frontier models on benchmarks and was released openly on Hugging Face. A Microsoft-published letter signed by nearly every major AI lab (except Anthropic) urges the US government not to ban open-weight models, arguing they are essential for innovation and independence from a few large providers. ✦ AI generated

Moonshot AAI released Kimmy K3, their biggest model yet. And on a lot of benchmarks, it is on par with Fable 5 and some of like the the Frontier models. And so, this freaked a lot of people out. If you were watching the news, you saw that like the US government was trying to come up with potential sanctions to like block usage of it. [...] But the reaction to let's just ban all openweight models was not received lightly. And so this letter gets into the the whole idea of innovation and like how we we keep moving and basically is just an argument for making sure that the US can continue have continued access to openweight models and potentially invest in research for more openweight models. And if you look at the signitories for this letter, it's literally every single AI lab out there, plus other technology companies except for Anthropic. Um, Google is on here. Uh, XAI is on here. Uh, Open AI is on here, but Anthropic is not yet on this list. Um, Llama, Meta.

39:12but I think using it to steal that information obviously is new. Uh and very wild honestly. Can can I get some uh YouTube ad rev for all the YouTube transcripts they they swipe from me? Like for real though. >> Like every every >> three grand for a YouTube video. >> Yeah. Give me three grand for every GitHub repo they they took of mine. some credit. Give me 10 bucks for every blog
39:35post that you've stolen from me. >> Exactly. All right, let's keep moving. The next story is about Open Weights. So, this was a letter published by Microsoft called Open Weights and American AI leadership. And so, last week we saw Kimmy K3 launched by uh is it Moon Moonshot? No, not Moonshot. Um um who does Kimmy? Who's the company? >> Moonshot. Moonshot. Moonshot. Okay. Yeah. So, Moonshot AAI released Kimmy
40:00K3, their biggest model yet. And on a lot of benchmarks, it is on par with Fable 5 and some of like the the Frontier models. And so, this freaked a lot of people out. If you were watching the news, you saw that like the US government was trying to come up with potential sanctions to like block usage of it. And there's this whole deal of uh did uh Moonshot distill Fable in order
40:23to create this really big model? Whole big mess. But the reaction to let's just ban all openweight models was not received lightly. And so this letter gets into the the whole idea of innovation and like how we we keep moving and basically is just an argument for making sure that the US can continue have continued access to openweight models and potentially invest in research for more openweight models. And if you look at
40:51the signitories for this letter, it's literally every single AI lab out there, plus other technology companies except for Anthropic. Um, Google is on here. Uh, XAI is on here. Uh, Open AI is on here, but Anthropic is not yet on this list. Um, Llama, Meta, >> Open Claw. What's the weirdest company on this list? Like Tim Horton's on here. >> Yeah. [laughter] >> Yeah. What was that one company that was
41:18relaunched as like an AI company that was known for something completely? >> All birds [laughter] is all did somebody contact all birds to get their opinion on this. >> I mean there's some management company I don't know most of these look like tech companies but the whole idea is everyone all of them the management at these companies are getting together and be like hey and this is really a letter for
41:38the US government. It's like don't ban open models. We need more research here. And this is basically what's going to allow us to not be completely dependent on open AI or anthropic. We need an openweight model ecosystem. So this letter is out there. Um and ideally this will prevent any sort of weird US sanctions on our ability to use openweight models. Leading from that is the release of
42:00Kimmy K3. So Kim K3 was launched last week uh via API access only. So the only way to use it was to talk to Kimmy's API servers to interact with K3. But today, literally hours ago, they released the model as openweight and you can now run it if you have two terabytes of uh VRAM. You can run it on your own um infrastructure if you really want to,
