Using it via the API

Call it like any OpenAI endpoint

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" \
