TechCrunch·high signal

OpenAI shipped three major Codex features in May: a Chrome extension for parallel browser-based agent work across tabs, ChatGPT mobile integration (iOS/Android, all tiers including Free) for remote monitoring and command approval, and persistent /goal workflows with runtime continuation and pause/resume controls. Codex now has 4 million weekly active users, an 8x increase since January 2026. The mobile feature lets developers approve agent commands from their phone while the agent works on a connected Mac.
