How do you start calling gpt-audio?

Use the model ID gpt-audio through the compatible Chat Completions endpoint. It accepts audio inputs and produces audio outputs.

What audio formats does gpt-audio support?

Confirm the current supported audio formats and duration limits in the model documentation. Test with your specific audio requirements.

What is the rate limit for gpt-audio?

gpt-audio rate limits vary by your MixRoute subscription plan. Check your plan details in the console for requests per minute (RPM) and tokens per minute (TPM) limits. Run a small load test before production to confirm your effective quota.

When was GPT-Audio released, and is it still maintained?

GPT-Audio is listed with catalog status stable. The recorded release date is 2026-01-19. Check the model page for deprecation notices before you build a long-lived integration on it.

What should you evaluate before moving production traffic to GPT-Audio?

Before switching production traffic to GPT-Audio, run a pilot on a representative slice of your traffic and check output quality, latency at peak concurrency, and cost per request. Verify the error and retry behaviour, and confirm the request limits you depend on match your plan.

Does GPT-Audio support streaming output?

Yes. GPT-Audio is declared as supporting streamed responses.

Can you call GPT-Audio with the OpenAI SDK you already use?

Yes. GPT-Audio is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to gpt-audio . Keep your current request and response handling.

What is this model good for?

An OpenAI model for conversations with audio input

An OpenAI model for conversations with audio input and output through the Chat Completions API.

What should you check before using it?

Confirm audio formats, sample rates, and pricing

GPT-Audio supports tool calling, streaming and the OpenAI SDK. Knowledge cutoff: 2023-10-01. Released 2026-01-19. The audio input price is $40.0000 per 1M tokens. Test a representative workload before production.

Why use it through MixRoute?

GPT-Audio runs tools and structured output here

Tool calling and structured output run on that route as well. MixRoute serves GPT-Audio on the OpenAI-compatible endpoint /v1/chat/completions; point your existing client at https://api.mixroute.ai/v1 with the model ID gpt-audio and re-run your integration tests.

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Tool calling

GPT-Audio supports function and tool calls.

EX Send a tools definition; the response returns tool_calls to execute and feed results back.

Streaming

GPT-Audio supports streamed responses.

EX stream: true streams tokens incrementally, so chat UIs render as they arrive.

OpenAI SDK

Call GPT-Audio through MixRoute's OpenAI-compatible endpoint.

EX Change base_url to https://api.mixroute.ai/v1; everything else follows the OpenAI style.
