Availability varies by plan — your live set is whatever onepin voices list returns. The Model ID column is what GET /providers/{provider}/models returns, and it is the value a Generator’s voice_map takes for model — see Generator.

Providers and models carry a beta flag in the catalog. It’s a badge, read live per request — staff can graduate something out of beta without a release — and it never affects whether you can use the model. A provider is badged beta only when every model you can see under it is.
