Deep Cogito
1 model built
Deep Cogito Inc. is a San Francisco startup, founded in 2024, building the Cogito series of open-sourced hybrid reasoning models — models that can toggle between a fast non-reasoning mode and a slower step-by-step reasoning mode depending on the task. Through OpenKey the lineup is a single model: Cogito v2.1 671B, a 671-billion-parameter release from November 13, 2025 with a 128K context window. It's priced at $1.25 per 1M input tokens and $1.25 per 1M output tokens (provider list price), which comes out to $1.2875 per 1M tokens on either side through OpenKey after the flat 3% fee. There's no free tier for this lab yet.
Lineup
With one model available, the choice is simple: use Cogito v2.1 671B for anything that benefits from switchable reasoning depth — quick answers when you don't need chain-of-thought, deeper reasoning mode when you do. At $1.25/$1.25 per 1M tokens (provider price; $1.2875/$1.2875 through OpenKey after the 3% fee), it sits in the mid-range for a 671B model, and the 128K context window covers most document and multi-turn use cases. There's no cheaper or free Deep Cogito model to fall back to, so budget around this one price point.
