DeepInfra

Use DeepInfra's hosted TTS models as your provider.

Setup

Environment variables (recommended for deployment):

API_BASE=https://api.deepinfra.com/v1/openai
API_KEY=your-deepinfra-key
NEXT_PUBLIC_DEFAULT_TTS_PROVIDER=deepinfra

Or in-app via Settings → TTS Provider:

1. Set provider to Deepinfra.
2. The base URL is pre-filled, no changes needed.
3. Enter your API_KEY.
4. Choose a model and voice.

Settings modal values override env vars. See TTS Providers for how the two layers interact.

Notes

• Available models include hexgrad/Kokoro-82M and canopylabs/orpheus-3b-0.1-ft.
• Without an API key, only the free-tier model (hexgrad/Kokoro-82M) is shown in the dropdown.
• TTS requests are sent from the server, not the browser. The API key is never exposed to clients.
