# Streaming model responses
To retrieve results from a [streaming model](https://docs.coveo.com/en/19#tag/Streaming-Model-Response), specify which model stream you want to retrieve results from by specifying a `streamId`.
You can find the available values that you can use as stream IDs for your query in the `extendedResults` of a [search request response](https://docs.coveo.com/en/13/api-reference/search-api#tag/Search-V3/operation/searchUsingPostV3-response-extendedResults).

> **Warning**
>
> Currently, the only [Coveo Machine Learning (Coveo ML)](https://docs.coveo.com/en/188/) [model](https://docs.coveo.com/en/1012/) which supports streaming is the [Relevance Generative Answering (RGA)](https://docs.coveo.com/en/n9de0370/) [model](https://docs.coveo.com/en/1012/).
> Other [models](https://docs.coveo.com/en/1012/) may add support for streaming responses in the future.
