Command A

Cohere's large language model with a 256K token context window, extending the depth available in the Command series for handling longer documents and extended conversations.

Strengths

Supports a significantly larger context window than other Command models, enabling work with longer documents, extended multi-turn interactions, and more comprehensive retrieval-augmented generation workflows.

Best for

Applications requiring processing of long documents, extended context retention, and RAG systems where a larger window can reduce the need for aggressive summarization or chunking.

Limitations

Larger context windows increase latency and token consumption; for many production workloads, the 128K window of Command R+ or Command R may be sufficient and more cost-effective.
