OpenAI is evolving its Codex desktop app into a broader AI superapp, adding background computer use (Mac only), an embedded Atlas browser, image generation via gpt-image-1.5, 90 new plugins, and persistent 'heartbeat' automations that run on a schedule without losing thread context. Codex now has 3 million weekly users growing by 1 million per month. New developer features include GitHub review comment handling, multiple terminal tabs, SSH remote devbox connections, and a summary pane. Inside OpenAI, over 80% of employees use Codex for tasks well beyond coding, including drafting briefs, reviewing contracts, and triaging Slack.
