OpenAI's ChatGPT Voice Gets Major Upgrade with Plugins and GPT-6 Models

On September 24, OpenAI officially announced a major ChatGPT Voice update, rolling out immediately in the latest version of the app worldwide. OpenAI President Greg Brockman called it a "mega upgrade."

Confirmed

• Voice mode can now invoke plugin tools directly, including external services like email, calendar, and Slack
• The underlying model lineup has been replaced with the GPT-6 series: Astra, Sol, and Luna
• The update is available on both web and mobile for ChatGPT Work

Why it matters

• User kimmonismus believes that with email, calendar, and Slack integration, voice mode's practicality has improved dramatically, making it a genuinely usable everyday voice assistant for the first time—though they note further real-world testing is needed
• kimmonismus also speculates this update may be preparation for voice interaction on OpenAI's own hardware products; this remains personal speculation
