GPT-Live-1 mini: the Voice fallback is not a developer SKU
The smaller Live model is part of ChatGPT's Free-tier experience. It is not a public API SKU, and “mini” is not a price.

GPT-Live-1 mini arrived July 8 as part of the ChatGPT Voice rollout. It is easy to read the name as a cheaper developer model. OpenAI's announcement does not support that reading yet.
For now, mini is a ChatGPT tier
OpenAI places GPT-Live-1 mini in the Voice rollout for Free users, while GPT-Live-1 is the default for eligible paid plans. That describes the experience a ChatGPT user may receive. It does not give a developer an endpoint, throughput promise, or billing unit.
The name contains no price
The announcement lists no context window, maximum output, rate card, or API model string for GPT-Live-1 mini. Do not borrow a rate from GPT-Realtime or another OpenAI mini family. They are separate products with separate terms.
The Voice response may include a handoff
OpenAI says the Live models can delegate deeper work to other OpenAI models. What the user hears may be the result of a larger system, not one model acting alone. If you need a buildable voice agent, write down the endpoint, billing, tool, privacy, and fallback requirements first.
