Chat completions

POST /v1/chat/completions mirrors the OpenAI Chat Completions API: the same model, messages, temperature, max_tokens, tools, tool_choice, and stream fields are accepted. Unknown fields are forwarded transparently upstream.

Every response carries two Sable-specific headers:

• x-sable-node — the Sable node that served the request
• x-sable-privacy-tier — the tier it executed under

Sable extensions

One additional body field is accepted: sable_privacy_tier. It overrides the tier inherited from the API key for that single call. See Privacy tiers.
