I see a change was pushed last night to the Inference product meaning these should now resolve.

1. Is `cartesia/sonic-3-latest` still Sonic 3.5, or is it now Sonic 3? → This is pointing at Sonic-3

2. If it is Sonic 3, is there a supported LiveKit Inference model ID for Cartesia Sonic 3.5? → Yes, the 3 models you listed that were previously ‘not found’ should now point to 3.5

3. Should we expect `cartesia/sonic-3.5` or `cartesia/sonic-latest` support soon? → Sorry I missed this message when it was originally posted
