Supported models
Every model alias exposed by CocoboxAI, with provider, context window, and per-request credit cost.
Every model is reachable via either /v1/chat/completions (OpenAI shape) or /v1/messages (Anthropic shape). Use whichever shape suits your client.

- Streaming: All aliases support SSE streaming on
/v1/chat/completionsand/v1/messages. - JSON mode: OpenAI aliases and
prisma/sonnetsupport strict JSON mode viaresponse_format. - Vision:

Picking via API
You can pass either the alias (prisma, tambor, …) or the underlying provider model id. Aliases are recommended for stability.
curl https://api.cocobox.io/v1/chat/completions \
-H "Authorization: Bearer $COCOBOX_API_KEY" \
-d '{"model":"prisma","messages":[{"role":"user","content":"hi"}]}'Deprecation policy
Aliases are stable. The underlying model can be upgraded with 30 days notice via the changelog and an email to workspace owners. Underlying ids (e.g. claude-sonnet-4-5-20250929) follow the upstream provider’s deprecation schedule.
