This is a breaking commit. "2025-04-16" does not support

  1. Embeddings
  2. stability cloning mode
  3. Experimental controls for adjusting speed and emotion.

You should revert this commit, or you should branching on this features.

Users who absolutely need embeddings or experimental controls should use API version 2024-11-13 with model ID sonic-2-2025-03-07, both of which are still available. Please be aware that these features could lead to reduced model stability even with that model.

These part of code still exists and are actually used by some users in the TTS.__init__() in the same file.
