GPT Audio
VerifiedOpenAI's GPT Audio processes text and audio with a 128k token context.
About GPT Audio
GPT Audio combines text and audio capabilities in a single system developed by OpenAI. Its large context window supports extended conversations or audio sequences without losing earlier details. The design prioritizes integration of spoken content with written instructions.
Strengths include handling both modalities natively while remaining proprietary. This allows consistent performance across audio transcription, generation, and text-based reasoning. Users benefit from the model's ability to maintain coherence over long inputs.
Typical usage covers voice interfaces, audio analysis, and mixed media applications. Developers integrate it into tools requiring speech understanding alongside textual context. The closed nature means access occurs through OpenAI's platforms rather than local deployment.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "openai/gpt-audio",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openai/gpt-audio
