additional_contextstring nullable

A string of extra context injected into the LLM call for this request. The context is passed to the model but is not stored in the database and will not appear in the chat history. Use this to supply ephemeral, request-scoped information (e.g. the user's current page URL, session metadata, or any runtime context) without polluting the persistent conversation history. Pass null or omit the field to use no additional context.

Response

If stream=true, returns text/event-stream. If stream=false, returns application/json (ChatFullResponse).
