Command-R (Mar '24)

Command R is a scalable generative large language model released by Cohere in March 2024, specifically designed for enterprise-grade workloads. It belongs to a category of models optimized for Retrieval Augmented Generation (RAG) and tool use, balancing high efficiency with strong accuracy to facilitate production-scale deployments. The model was released under the Cohere For AI (C4AI) initiative as an open-weights research release.

Key Capabilities

The model features a 128,000-token context window, allowing it to process and reason over extensive documents. It is uniquely trained to generate responses with clear in-line citations, which helps mitigate hallucinations and allows users to verify information against source materials. Additionally, Command R is optimized for tool use, enabling it to interact with external APIs, databases, and search engines to automate complex business workflows.

Multilingual and Technical Details

Command R supports 10 key languages natively: English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Arabic, and Chinese. It utilizes a specialized tokenizer that improves efficiency for non-English text, reducing latency and operational costs. Architecture-wise, the model consists of 35 billion parameters, positioned to provide a competitive balance between performance and the hardware requirements for self-hosting.
