Developers can customize the AI's tone, pacing, and conversational style, with improvements in handling background noise and long sessions. GPT-Live-1 is already powering new voice modes in ChatGPT and offers a 30% performance increase over its predecessor, GPT-Realtime-2.1. AI

IMPACT Enables more natural, interactive, and customizable voice AI experiences, potentially accelerating adoption in applications like customer support and personal assistants.
