GPT-Live Hub

GPT-Live Hub is an independent reference and planning tool for OpenAI's real-time voice product, GPT-Live. Its core utility is a cost calculator: you enter audio minutes or actual token counts and it estimates what API usage would cost, then puts the published ChatGPT Live plan limits side by side so you can see where a subscription stops and API billing starts.

Around the calculator sits a documentation hub covering the GPT-Live API release timeline, the expected shape of the streaming real-time voice endpoints, pricing signals, comparisons against Advanced Voice Mode, and how to join the developer waitlist. Pages carry an explicit review date - the API page was last verified on 2026-07-10 - and are attributed to a named editorial team, which is more provenance than most tracker sites publish.

It is worth being clear about what this is: an independent third-party resource, not an OpenAI property and not the API itself. Much of the endpoint and pricing detail is described as signals and expectations for a product still in developer preview, so treat it as a planning aid rather than official documentation. Useful for developers and finance owners sizing a real-time voice feature before access opens, and for anyone deciding whether a ChatGPT subscription or API billing is the cheaper route. The site does not publish a price for itself.
