OpenAI Codex Ships Appshots, Goal Mode GA, Remote Computer Use, and In-App Browser in Build 26.519

OpenAI Developers·high signal

OpenAI's Codex app shipped a major update on May 21 with four significant features: Appshots lets developers press both Command keys to inject the frontmost Mac window (screenshot + text) into a Codex thread; Goal Mode graduates from experimental to GA across app, IDE extension, and CLI, enabling multi-day autonomous objectives; Remote Computer Use lets Codex control desktop apps after Mac locks via an Apple authorization plug-in with short-lived authorization and relock-on-input safeguards; and the in-app browser lets Codex operate local dev servers for visual verification. Combined, these move Codex toward always-on autonomous development.
