OpenAI releases new macOS app for Codex, enhancing agentic coding with parallel agents, automated workflows, and customizable personalities.
San Francisco: OpenAI has introduced a new macOS app for its Codex coding tool. The app lets multiple AI agents work together on coding tasks. It includes features like automated workflows and different agent personalities to match how people like to work.
What Makes This App Different
The app can run tasks automatically in the background. It puts the results in a queue for users to check later. People can choose how the AI acts—from very practical to more understanding. The company says this helps programmers write code much faster.
How It Compares to Other Tools
OpenAI’s newest model GPT-5.2-Codex scores highest on some coding tests. But other AI systems like Gemini 3 and Claude Opus get similar scores when doing real-world coding tasks. The company hopes its new interface will make the powerful model easier to use.
OpenAI CEO Sam Altman says programmers can create complex software very quickly with this tool. He says if you can type your ideas fast enough, you can build sophisticated programs in just a few hours.
