Frequently asked questions

What Deezer models can I run on ModelRunner?

The catalog has 1 public Deezer model: Spleeter. It covers audio-to-audio. It has its own page with a free playground, the full input schema, and copy-paste code.

How much do Deezer models cost?

Pay-per-use, with no subscription: the one Deezer model billed per audio clip costs $0.0025, and every page publishes its own rate — some are tiered, so a lower resolution or a shorter clip costs less per run. You buy credits and pay only for what you generate.

How do I call a Deezer model from the API?

POST to https://queue.modelrunner.run/deezer/spleeter with an Authorization: Key header and the input fields as the top-level JSON body (no wrapper object), then poll the returned status_url and fetch the result from response_url. The JavaScript SDK (@modelrunner/client) wraps that in a single subscribe() call, which is the one place an { input } object is used.

Can I run Deezer model from Claude or Cursor?

Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and Deezer's model becomes a tool your assistant can call with run_model — authorized over OAuth 2.1, so no API key goes into a config file. Results come back as hosted URLs in the conversation.

Where is the source code or paper for Deezer models?

1 of the 1 Deezer model in the catalog link their own upstream sources — Spleeter — covering some combination of code repository, paper, weights and licence. The links are listed on this page and on each model's own page.
