Catalog questions
How do I browse available models?
Visit /models or use the CLI: runapi models list. Filter by modality, provider, or search by name.
Can I use multiple models in one project?
Yes. One API key works across all 250+ models. Switch between video, image, music, audio, and LLM models freely.
How are new models added?
We add new models continuously. Major releases are typically available within days of launch. Follow our changelog for updates.
Can I request a specific model?
Yes. Contact us with the model name and provider. We evaluate all requests and prioritize based on demand.
What happens when a model is retired?
We notify users 30 days before retirement. Your existing code continues working — just update the model parameter to a newer version.
How are models priced?
Text models bill per million input and output tokens; media models bill per second, per image, or per minute. Every rate is listed on the model page and in the pricing table.
