OpenAI’s GPT‑Bidi‑1 will let ChatGPT talk and listen at once
OpenAI is testing a bidirectional audio model called GPT‑Bidi‑1 for ChatGPT Voice, letting the assistant listen and speak simultaneously and handle interruptions without freezing. The upgrade adds tiered intelligence modes so users can trade reasoning depth for lower latency, signaling a push to close the gap with its newer text models.
