Source: DeepSeek API Docs

Chinese lab DeepSeek released DeepSeek-R1, a reasoning model trained largely with reinforcement learning that it said matches OpenAI o1 on maths, code and reasoning. Weights were published under the MIT licence alongside six smaller distilled models, and API output was priced at $2.19 per million tokens.

Why it matters

Developers can download R1’s weights under the MIT licence and run a model DeepSeek says matches OpenAI o1, or pay $2.19 per million output tokens through its API.
