Summary

Melvin Vivas reshares OpenAI's announcement that ChatGPT Voice now runs in the ChatGPT desktop app. A one-minute demo shows someone using only their voice to control the computer, draft launch blog posts, brainstorm a feature and ask for pushback, and send Codex to check feature flags and find a bug's root cause in a new thread with a pull request. The announcement says the feature runs on GPT-Live, which can speak, listen and coordinate work in the app at the same time. The post is a product showcase, not a tutorial.

Key points

• ChatGPT Voice is now in the ChatGPT desktop app and is rolling out globally (according to the quoted announcement).
• With voice alone you can control your computer and direct several agents running in ChatGPT Work or Codex.
• It runs on GPT-Live, a model that can speak, listen and coordinate work in the app at the same time.
• Demo workflow: draft launch blog posts by voice, then 'ramble' about a feature idea and ask the assistant to ask questions and push back.
• Codex gets voice-delegated tasks: check that feature flags are configured correctly, and spin up a new thread to open a pull request and find a bug's root cause (here, a misconfigured feature flag).
• Goal-based delegation: set a goal, tag the team for review later and check in from your phone; the assistant creates follow-up goals.
