Command-R+ by Cohere: Open-Weight RAG-Optimized AI Model

Command-R-Plus

Advanced RAG-Centric AI by Cohere

What is Command-R+?

Command-R+ (also known as Command-R-Plus) is Cohere’s flagship open-weight language model, purpose-built for retrieval-augmented generation (RAG). It builds on the architecture of Command-R but features enhanced capabilities, including support for 128K token context, superior accuracy, and lower hallucination rates in document-grounded tasks.

Whether you’re powering enterprise search, QA bots, summarizers, or agentic systems, Command-R+ gives you production-grade RAG performance—with fully open weights for unrestricted development and research.

Key Features of Command-R+

128K Context Window

Ideal for document-heavy tasks like legal QA, research synthesis, and full-report summarization.

RAG-Optimized Design

Engineered to integrate seamlessly with retrieval systems—vector databases, search APIs, and knowledge graphs.

Grounded Generation Accuracy

Reduced hallucination risk through fine-tuning on retrieval-augmented instruction tasks.

Open-Weight, Permissive License

All model weights, tokenizer, and configs are available—allowing local deployment, research, and fine-tuning.

Efficient Inference at Scale

Optimized for speed and stability across enterprise GPUs and deployment environments.

Customizability for Vertical Domains

Fine-tune or adapt the model to your unique data in industries like healthcare, legal, fintech, or education.
