GPT-Live-1 is a ChatGPT Voice rollout, not an API endpoint
GPT-Live-1 changes ChatGPT Voice. It does not yet give developers an endpoint, a model ID, or an API price to build around.

ProductVoiceChatGPT rollout
OpenAI introduced GPT-Live-1 on July 8 for ChatGPT Voice and said API access was planned. That last word matters. The product exists, but the developer contract does not.
You can use it in ChatGPT, not your stack
GPT-Live-1 is the full-duplex Voice model rolling out to eligible ChatGPT Go, Plus, and Pro users. That tells you where the product can be tried. It does not give you a stable model string, an API endpoint, or a production rate card.
Full duplex is the feature
OpenAI says the Live models can listen and speak in the same interaction, then hand deeper work to other OpenAI models. The announcement does not publish a context window, output cap, benchmark table, or API price. A ChatGPT plan price cannot fill those blanks.
Run the product trial now; plan the integration later
A support or research team can test whether the Voice experience helps a user today. A developer team still cannot estimate API spend or promise endpoint behavior from this launch post. Write down the endpoint, billing, privacy, tool, and fallback requirements, then wait for documentation that answers them.
