Frequently asked questions
Which audio generation API is best in 2026?
It depends on your use case — ElevenLabs, MiniMax and Chatterbox are among the strongest right now. Because every model here runs on one Pixazo endpoint, the fastest way to decide is to test them on your own inputs.
Can I switch between these models without changing my code?
Yes. Pixazo exposes every audio generation model through a single API — you change one model parameter, not your integration, and billing stays unified.
Are new models added automatically?
This list is refreshed from Pixazo’s live audio generation catalog, so newly launched models appear on the same endpoint as they go live.
How does pricing work?
Pay-as-you-go through one key, with no per-provider contracts. See the Audio Generation API page for current rates.
Is there a free audio generation API to start with?
Yes. Create a free key from the Pixazo API console and call any model on this list right away, then move to pay-as-you-go as your volume grows.
Do I need a separate API key for each model?
No. One Pixazo key works across every audio generation model here, so you can benchmark and switch models without managing separate credentials or contracts.
Which model should I start with?
ElevenLabs, MiniMax, Chatterbox are strong defaults today. Because they share one endpoint, the fastest way to choose is to run the same input through each and compare the results.
Can I use the outputs commercially?
Commercial rights depend on the specific model you call. Check each model page for its licensing terms before shipping to production.
How do I get started with the audio generation API?
Grab a key from the API console, pick a model from the list above, and send your first request to the unified endpoint.
