Replicate

Use Replicate's hosted TTS models as your provider.

Setup

Recommended (auth + admin): Settings → Admin → Shared providers

1. Add a shared provider with type replicate.
2. Enter your API key.
3. Set default model to: alphanumericuser/kokoro-82m:89b6fa84e4fa2dd6bd3a96be3e1f12827a3516c9fda8fddbac7a0be131c9a6f5 (or your preferred model).

Legacy bootstrap seed (optional, first boot only):

API_KEY=r8_...

Then update the shared provider's Default model in Settings → Admin → Shared providers.

Per-user Settings → TTS Provider (only when restrictUserApiKeys=false):

1. Set provider to Replicate.
2. Enter your API_KEY.
3. Choose a model and voice.

See TTS Providers for admin-shared vs per-user behavior.
