## 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 55

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

### OpenRouter (B)

Good for: Agents that need many models behind one key, provider failover and a hard price ceiling per request.

Ahead on:
- Schema & documentation, 90 against 84
- Agent ergonomics, 85 against 72
- Payments & pricing, 40 against 30
- Maintenance & community, 84 against 72

Watch for: No machine payment. USDC top-ups go to a prepaid balance

## 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.

**OpenRouter.** Public OpenAPI document, llms.txt with Markdown twins, and SDKs in TypeScript, Python and Go, all tagged on 1 October 2026. No machine payment. USDC top-ups go to a prepaid balance.

## 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

### OpenRouter

1. Set `provider.data_collection: "deny"` or `provider.zdr: true` when the prompt holds anything private
2. Pass a `models` list so a failed provider falls through to the next one
3. Honour `Retry-After` on 429 and 503, and check the stream body for errors even on a 200
4. Set `max_price` so a routed request can't land on an expensive provider
5. Free models allow 50 requests a day until $10 of credit has been bought. Check `GET /api/v1/key` for what's left
