This page explains how UK teams use NextModel's OpenAI-compatible gateway. Audio SKUs today, and why this page ships no audio snippet yet. It adds the practical steps, configuration notes, and common questions.
Audio models today
Text-to-speech is live: POST /v1/audio/speech with a speech model from GET /v1/models (currently the openai/tts-1 family), billed per 10k input characters. Audio transcription routes exist but are not open yet on this deployment — a call returns 404 transcription_ingress_disabled until the flag is switched on. Audio SKUs are billed per 10k input characters; the dashboard playground covers audio trials. This page will carry tested TTS snippets the day the audio contract is verified against the live API — we do not publish untested code.
