It is useful if you need inline citations or OpenAI-compatible responses, but has limited functionality compared to the standard chat interface.

If false, the assistant will return a single JSON response. If true, the assistant will return a stream of responses.
The large language model to use for answer generation
Controls the randomness of the model's output: lower values make responses more deterministic, while higher values increase creativity and variability. If the model does not support a temperature parameter, the parameter will be ignored.
Optionally filter which documents can be retrieved using the following metadata fields.
Example:
{ "genre": { "$ne": "documentary" } }
