Former OpenAI CTO launches new model, letting users train AI themselves! Startup valuation reportedly sprinting toward 260 billion.

What happened: Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, released the general multimodal model Inkling 2 Small, with open weights planned for next week under the Apache 2.0 license. Key numbers: AA Intelligence Index score 31, up from 13 for Inkling-Small. 594 billion total parameters, 170 billion activated per token. Why it matters: The model targets custom training, letting developers train on their own data via the Tinker platform. The company says it will rank first among open-weight models developed outside China on the AA index once weights open.
