GPT-4o Realtime

by OpenAI

GPT-4o Realtime is the full-capability member of OpenAI's realtime voice family, enabling stateful, interactive voice conversations with minimal latency. As a native speech-to-speech model it takes audio in and generates spoken responses directly, preserving GPT-4o's reasoning depth inside a streaming voice interface. It supports function calling for agentic workflows, and voice activity detection handles silence automatically to keep exchanges responsive. It suits sophisticated voice assistants and virtual agents that need to reason over conversation context, and applications where speech interaction complements or replaces text.

Get started

Call GPT-4o Realtime through the qynio gateway with one API key. Let your coding agent set it up, or call it directly β€” qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "openai/gpt-4o-realtime",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
