OpenAI Developers announced a voice agent in Codex, powered by GPT-Live-1. A linked post from a Codex team member says Codex voice can now be used from a phone, connecting to the user's computer from anywhere, and identifies the new GPT-Live-1 model as the engine behind it.
The practical change is that a Codex session on a workstation can be directed by voice while the developer is away from the keyboard, which suits review and delegation more than detailed editing. The posts give no details on availability tiers, latency, pricing or how voice commands are confirmed before code changes.
