ChatGPT Voice Gets Major Upgrade: Plugins, GPT-6 Models, and Work Support

OpenAI officially announced a major ChatGPT Voice update on 09-24, rolling out globally with the latest version of the App starting today. OpenAI President Greg Brockman called it a "mega upgrade." The update transforms the voice assistant from something that could merely chat into one that can actually get work done, and is seen as a substantive leap forward for ChatGPT's voice experience.

Confirmed

Voice mode can now invoke plugins directly, including external tools like email, calendar, and Slack, enabling tasks such as checking email, scheduling, and performing actions on web pages.
The underlying models have been switched to three GPT-6 series models: Astra, Sol, and Luna.
The feature is available on both web and mobile in ChatGPT Work, with voice support covering all new models on the platform, meaning entire office workflows can be completed entirely by voice.
The update is rolling out globally starting today.

Why it matters

User kimmonismus believes that with voice access to email, calendar, and Slack, its practical utility has increased roughly a hundredfold, making it a truly usable everyday voice assistant for the first time; they also speculate this capability is paving the way for voice interaction on OpenAI's own hardware products.
User aziz4ai noted that voice support across all new models and its arrival in the Work version means office scenarios can now be fully voice-driven, a key step in the product's evolution.
