Frequently asked questions

What Resemble AI models can I run on ModelRunner?

The catalog has 5 public Resemble AI models: Chatterbox HD Voice Conversion, Chatterbox HD TTS, Chatterbox Multilingual TTS and 2 more. They cover sound. Each one has its own page with a free playground, the full input schema, and copy-paste code.

How much do Resemble AI models cost?

Pay-per-use, with no subscription: the 5 Resemble AI models billed per second of audio start at $0.00025, 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 Resemble AI model from the API?

POST to https://queue.modelrunner.run/resemble-ai/chatterboxhd/speech-to-speech 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 Resemble AI models from Claude or Cursor?

Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and all 5 Resemble AI models become tools 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.
