People who talk to ChatGPT get more natural conversation on every plan; developers pay 5 cents a minute plus backend model costs.

Kenning's take

What it does

GPT-Live is OpenAI's family of voice models that can listen and talk at the same time, so conversations feel less turn-based. It powers ChatGPT Voice, with GPT-Live-1 the default on paid plans and GPT-Live-1 mini for free users, and hands harder questions to a stronger model in the background. Developers got GPT-Live-1 in the API in September 2026.

• Full-duplex listening and speaking
• Hands reasoning and tools to a backend model
• Live translation
• GPT-Live-1 mini for free users
• API access billed per minute

Who it suits. ChatGPT users who talk to the app, and developers building voice agents.
