Cohere developed Command R as an enterprise-focused large language model.

Command R is a generative LLM optimized for retrieval-augmented generation, tool use, and long-context reasoning.

Available via Cohere's API and as open weights on Hugging Face under CohereLabs.

Released March 2024, with Command R+ following the same month and later updates through 2024.

Built to power production RAG and agentic workflows with strong multilingual and citation support.

Runs via the Cohere API, or self-hosted through Hugging Face transformers with the open-weight checkpoint.

Open weights (CohereLabs/c4ai-command-r) under CC-BY-NC with an acceptable-use addendum; watch Cohere's terms, hosted API requires a Cohere API key.
