Please see the list of [supported models](https://openindexai.gitbook.io/openindex.ai-api-documentation-1/reference/api-reference/supported-models) for the `model` parameter above.

If you pass `true` to the parameter `streaming`, the API will open a stream returning a [JSON Lines](https://jsonlines.org/) format (i.e. one json object per line).
