> SWE-2 is post-trained from Kimi K3

On the one hand I would have expected a completely new model, on the other hand it's an RL-ed K3 go Fable 5 capabilities, which demonstrate that this is probably possible, which is nice.

I thought it would be GLM based, as Devin has had free GLM-5.2 for a while now

why are all American AI models basically Kimi in a trench coat

No one in the US is going to fund pretty good open source with VC money.

US has OpenAI/ Anthropic/ Google/ meta/ SpaceX atleast trying to make frontier foundation models 2 are using VC money + cash flow, last 3 are mainly cash flow + equity and debt.

China has state banks and similar willing to fund lower margin open source labs.

It's (one of) the best freely available?
