https://platform.openai.com/docs/guides/realtime?use-case=transcription#connection-details The code to obtain a session token contains: body: JSON.stringify({ model: “gpt-4o-transcribe”, }), which fails. The client code points to: const baseUrl = “ https://api.openai.com/v1/realtime/transcript…

Hey @osv . Sorry for the confusion. The new transcription mode only works with Websockets at the moment. We adjusted the docs accordingly.

Any timeline for Webrtc support?

I do not know if it helps but this websocket implementation seems to work for me: import { getToken } from './backend.r.js' async function getWS() { const EPHEMERAL_KEY = await getToken() const ws = new WebSocket( 'wss://api.openai.com/v1/realtime?intent=transcription', [ 'realt…

@dkundel Any timeline on when WebRTC will be supported?

@dkundel are there any docs or examples on how to set up a transcription session via webrtc? or could you share which connection details should be used? base url, query params and headers Thanks!

@dkundel Still doesn’t work for me. Here is my code: const baseUrl= "https://api.openai.com/v1/realtime/transcription_sessions"; const model = "gpt-4o-transcribe"; sdpResponse = await fetch(`${baseUrl}?model=${model}`, { method: "POST", body: offer.sdp, headers: { …

@dkundel any update on this? I am blocked on a project

WebRTC support has been deployed. See Realtime Transcription for an example.

@juberti Thanks so much for sharing the demo! It looks great. I was hoping to understand more about how it’s set up to work with WebRTC, though — is there any documentation or setup guide I could follow?

Figured it out! Had to first create a session before establishing the WebRTC connection.
