Which one, for what

Cohere Chat API (Command models) B

Good for Teams that want Command models for RAG with citations, tool use and multilingual work, and that may later move to a private deployment or Model Vault.

Ahead on

  • Reliability, 64 against 50

Also in its favour

  • Free to start without a card

Watch for

Production keys work like trial keys on Command A+, Reasoning, Translate and Vision. The docs send production use of those models to sales or to Model Vault

Mistral AI API BB

Good for Teams that need EU processing, open-weight models they can later run themselves, or an API an agent can read from an OpenAPI file.

Ahead on

  • Schema & documentation, 93 against 84
  • Agent ergonomics, 91 against 72
  • Security & auth, 66 against 57
  • Payments & pricing, 40 against 30
  • Maintenance & community, 88 against 72
  • Transparency & trust, 80 against 74

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Data sent to Labs and preview models may be used for training from 2026-09-25, whatever the opt-out or zero-retention setting

Verdicts

Cohere Chat API (Command models)

A public OpenAPI file, Markdown twins of every docs page and SDKs in four languages make the Chat API easy for an agent to read. Production keys do not cover the four newest Command models, whose limits are set by sales, and the SaaS agreement lets Cohere share API data with third parties.

Mistral AI API

Public OpenAPI document at docs.mistral.ai/openapi.yaml and an llms.txt with Markdown twins. Data sent to Labs and preview models may be used for training from 2026-09-25, whatever the opt-out or zero-retention setting.

Before you call either

Cohere Chat API (Command models)

  1. Call POST https://api.cohere.com/v2/chat with Authorization: bearer <key>. model and messages are the only required fields
  2. Use command-a-03-2025, command-r-08-2024, command-r-plus-08-2024 or command-r7b-12-2024 for production traffic. Newer variants stay at trial limits on a production key
  3. Keep a trial key under 20 chat requests a minute and 1,000 calls a month, and do not use it for commercial work
  4. Set response_format with a json_schema for structured output, and tell the model to produce JSON when using json_object without a schema
  5. Ask the account Owner to turn off training under Data Controls in the dashboard before sending confidential prompts

Mistral AI API

  1. Stay off labs-* and preview models for anything confidential
  2. Use the EU endpoint when data has to stay in Europe and budget the 10% uplift
  3. Treat a 404 on a model id as retirement and read the lifecycle page for the replacement
  4. Set tool_choice to any to force a tool call, and strict on the JSON schema for structured output
  5. Read docs.mistral.ai/openapi.yaml for the request shapes instead of guessing from OpenAI's
