Deep Cogito goes big, releasing 4 new open source hybrid reasoning models with self-improving 'intuition'

Deep Cogito, a lesser-known AI research startup based in San Francisco founded by ex-Googlers, has released four new open-ish large language models (LLMs) that attempt something few others do: Learning how to reason more effectively over time — and get better at it on their own.

The models, released as part of Cogito's v2 family, range from 70 billion to 671 billion parameters and are available for AI developers and enterprises to use under a mix of limited and fully open licensing terms. They include:

Cogito v2-70B (Dense)

Cogito v2-109B (Mixture-of-experts)

Cogito v2-405B (Dense)
