OpenAI has developed GPT-Live, a new voice infrastructure for ChatGPT that enables full-duplex, turnless conversations. This system continuously processes incoming speech while generating audio, allowing for simultaneous listening and speaking, and seamless interruptions. By separating the voice handling from deeper reasoning tasks, which are managed by models like GPT-5.5 Instant and GPT-5.5 Thinking, OpenAI ensures that slow operations do not disrupt the conversational flow.

IMPACT Enables more natural and responsive voice interactions, potentially accelerating adoption of voice-based AI assistants.
