Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys f5-tts for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (f5-tts below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -F model="f5-tts" -F file=@audio.mp3

Licence

Commercial licence needed

The weights are open but cc-by-nc-4.0 needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
