GPT-Live-1

OpenAI's full-duplex speech-to-speech voice model, released July 8, 2026 alongside a lighter GPT-Live-1 mini. It has replaced Advanced Voice Mode as ChatGPT's default voice experience.

GPT-Live-1 strengths

• Full-duplex: listens and speaks simultaneously
• Natural interruptions and backchanneling
• Live translation
• Delegates web search and reasoning to GPT-5.5 for harder tasks

Pricing & context

There is no API pricing to model yet: OpenAI has announced API access as "coming soon" but has not published rates. Today, GPT-Live-1 is used through ChatGPT — the full model on Go ($8/mo), Plus ($20/mo) and Pro plans, with GPT-Live-1 mini rolling out to Free users.

A voice model, not a text LLM

GPT-Live-1 is a speech-to-speech voice model, not a text LLM, so it is not directly comparable to models like GPT-5.5 on text benchmarks. Instead of competing on reasoning scores, it delegates: for harder tasks it hands web search and reasoning to GPT-5.5 behind the scenes while it handles the live conversation.

When to choose GPT-Live-1

GPT-Live-1 replaced Advanced Voice Mode as the default voice experience in ChatGPT, so most users will meet it there rather than choose it. It is built for natural spoken conversation — interrupting mid-sentence, backchanneling, and live translation — rather than text work. Developers wanting to build on it will need to wait for the API, which OpenAI has announced but not yet priced.
