Using it via the API
Once AxForge deploys vieneu-tts-q4 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (vieneu-tts-q4 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="vieneu-tts-q4" -F file=@audio.mp3

Licence
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 ↗
