# Other Models

> Utility models outside the image, video, and audio categories, with links to compatible chat APIs

This category contains utility models that do not fit the image, video, or audio categories. They use the APIXO Generation API workflow.

For Claude, OpenAI Responses, and Gemini-compatible chat or streaming APIs, use the [Chat API](/docs/llm) instead.

## Start building

* Read the [Generation API overview](/docs/models) for the shared task workflow.
* Use [Generate Task](/docs/api-reference/generate-task) to submit a utility request.
* Use [Status Task](/docs/api-reference/status-task) when the selected utility returns a task ID.
