sonic-2 stops working on October 20, 2026 (Cartesia) #59

Hi! A short heads-up, in case it hasn't reached you yet.

sonic-2 stops working on October 20, 2026. After that, Cartesia returns an error for requests that name it.

Cartesia's notice: “sonic-2 and sonic-turbo models will be deprecated on October 20, 2026, while certain sonic-3 snapshots face the same timeline” (source)

It's still used here:

• src/voxforge/infrastructure/providers/tts/cartesia.py:41: "model_id": "sonic-2",

What to use instead: sonic-3.6 (or sonic-3.5, sonic-3). Price: same price.

If you'd like, reply here and I'll open a pull request with the change.
