How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
The official material describes research and demonstrations rather than a public inference service, so it does not publish developer request-retention, training-use, or residency terms.
The public beta page does not state a complete retention or model-training policy for prompts, lyrics, and generated audio. Review the live terms before uploading unpublished or confidential material.
