How it works
Using it via the API
Once AxForge deploys lavasr for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (lavasr 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="lavasr" -F file=@audio.mp3
Create an account — your API key is available in the console. 5M tokens/month currently included with every new account at launch.
