# Command A

> Cohere multilingual model for enterprise chat, retrieval-augmented generation, and tool workflows.

Cohere multilingual model for enterprise chat, retrieval-augmented generation, and tool workflows.

## Model Information

| Field        | Description               |
| ------------ | ------------------------- |
| `model`      | command-a-03-2025         |
| `context`    | 256K tokens               |
| `max output` | 8K tokens                 |
| `endpoint`   | POST /v1/chat/completions |

Context and output sizes describe the model specification. Effective request limits, availability, and billing depend on the MixRoute route.

## Capabilities and Usage

* Uses command-a-03-2025, a distinct model from Command A+.
* Use text messages for this integration. Native Cohere documents/citations features are not automatically enabled by switching the model ID on Chat Completions.
