• Greg Brockman (OpenAI) highlighted GPT-Live’s new realtime-audio architecture — Posted at 10:25 pm UTC on 3 August, roughly 14½ hours before this check, Brockman described GPT-Live as a new architecture and stack for realtime audio. The underlying OpenAI announcement says the system can keep listening while it speaks and maintain a continuous audio stream, allowing deeper reasoning and tool calls without interrupting the conversation.
