OpenAI Codex Voice, Heartbeats, and ChatGPT Sites Demo
A How I AI podcast episode with Nick Baumann (OpenAI Developer Experience) demos recent ChatGPT capabilities: Codex Voice (multi-person voice chat, screen-reading orb, background tasks) that can operate a computer via a hotkey and Appshots and supports thread‑forking to spawn parallel threads for tasks like booking travel and filing expenses. He showcases ChatGPT Work on mobile using Heartbeats—always-on, no-code agent-style notifications for suspicious charges, package proximity, and important emails—and a live ChatGPT Sites deployment workflow that includes SQL databases, file storage, environment variables, and email access for fast site builds. Baumann also demos an AI-driven UGC video-editing workflow that ingests many raw clips, transcribes them, selects best takes, and assembles vertical videos overnight. The episode is available on YouTube, Spotify, and Apple Podcasts.
Feature updates from OpenAI expand conversational voice workflows, mobile automation, and rapid site deployment—relevant for marketers and creators adopting AI-driven workflows but not an industry-level platform policy change.
