Frequently asked questions
Can these APIs turn speech or audio into video?
Yes. These lipsync models also power speech-to-video and AI dubbing — feed a portrait plus speech or audio and they generate a talking-head video with matched lip movement, all from the same Pixazo endpoint.
Which lipsync API is best in 2026?
It depends on your use case — Kling 3.0, Pixverse v6 and Heygen 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 lipsync 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 lipsync catalog, so newly launched models appear on the same endpoint as they go live.

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 lipsync model here, so you can benchmark and switch models without managing separate credentials or contracts.
Which model should I start with?
Kling 3.0, Pixverse v6, Heygen 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?
