DeepSeek: R1

DeepSeek R1 is here: Performance on par with [OpenAI o1](/openai/o1), but open-sourced and with fully open reasoning tokens. It's 671B parameters in size, with 37B active in an inference pass....

Tool useReasoning

Why it stands out

Combines tool use with reasoning — a strong baseline for agentic and multi-step workflows.

What to watch

Text-only input — image or audio workflows require a separate model in the pipeline.
64K context window is shorter than the longest-context frontier models available today.
No benchmark score currently tracked — evaluate using task-specific testing alongside pricing and capability data.
