# non_streaming_not_supported

> HTTP 400 — Model requires streaming.

## HTTP status

`400 invalid_request_error`

## Typical cause

The request sets `stream: false` (or omits it) but the selected model only supports streaming responses.

## Resolution

Set `stream: true` or choose a model that supports non-streaming requests.
