How it works
Using it via the API
Once AxForge deploys convtasnet-libri2mix-sepclean-16k for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (convtasnet-libri2mix-sepclean-16k 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="convtasnet-libri2mix-sepclean-16k" -F file=@audio.mp3
