OpenAI released a native Codex app for macOS. This is a direct attack on the autonomous coder market where Claude Code and Cursor have dominated. Nothing fundamentally new in Codex (it's just a new interface instead of plugins and terminal tools). But the direction is popular (standalone app) + PR opportunity.
What it does:
- Like Claude Code: Not autocomplete (like Copilot), but a full agent. You can assign it a one-hour task (refactoring, migration) and minimize the window.
- Parallelism: Codex runs multiple agents simultaneously. One fixes bugs, another writes tests.
- Skills: Similar to Claude's tools. The agent works with terminal, Git, and file system in a secure sandbox.
The "vibe coding" era (by the way, that word turns one year old tomorrow!) continues: you set a task, the neural network does everything else.
