Codex for macOS 26.601.21317

Codex for macOS is OpenAI’s native desktop command center for agentic software development—built to effortlessly manage multiple agents at once, run work in parallel, and collaborate with agents on long-running tasks.

Organized by project, the Codex app keeps each agent thread’s context and progress visible, so you can switch instantly without losing the thread—while staying in control through reviewable diffs, built-in Git tools, and worktrees for isolating changes.

Models (OpenAI): gpt-codex, gpt-codex-mini, plus gpt-codex-max,  gpt. (Codex can also be configured to use other models/providers that support the OpenAI Responses API.)
