Is Codex (OpenAI) Down?

Codex Chronicle launched 2026-04-20/21 as an opt-in research preview for ChatGPT Pro on macOS only (NOT available in EU/UK/Switzerland). Captures screen content + builds persistent memories so Codex understands what you're working on without manual context-restating. Privacy details: screenshots stored locally in $TMPDIR/chronicle/screen_recording/ auto-deleted after 6 hours; generated memories live unencrypted as markdown at ~/.codex/memories_extensions/chronicle/; OpenAI servers don't retain processed screenshots and don't train on them. OpenAI explicitly flags 'increased prompt-injection attack surface from screen content' -- pause Chronicle before meetings or sensitive material. Currently consumes rate limits aggressively. Closest comparison is Microsoft Recall but with stronger local-storage guarantees

CLI was macOS-only at launch, frustrating Windows and Linux users -- broader platform support now rolling out

Code quality for complex tasks often needs significant human review before merging -- better at code review than code writing according to developer feedback

2026-04-16 Codex 'super app' update is substantially bigger than the initial Mac-app control headline suggested. Full feature set per OpenAI: (1) macOS computer-use agent that opens apps, clicks, and types with its own cursor in background while you use your machine, (2) image generation via gpt-image-1.5 INSIDE Codex, (3) persistent memory + user preferences across sessions, (4) in-app browser built on the Atlas browser stack, (5) 90+ new plugins combining skills, app integrations, and MCP servers. OpenAI also disclosed 3M weekly Codex users with 70% month-over-month growth. Windows / Linux computer-use support still pending. Not available in EEA, UK, or Switzerland
