OpenAI Unleashes AI Coder App on MacOS
2 Feb
Summary
- New MacOS app for Codex integrates agentic practices.
- GPT-5.2-Codex model offers advanced capabilities.
- Codex app aims to speed up software development significantly.

OpenAI has introduced a new MacOS application for its Codex coding tool, incorporating popular agentic software development practices. This move aims to enhance human-AI collaboration in programming.
The new Codex app facilitates parallel work with multiple AI agents, integrating their skills and advanced workflows. It is powered by the GPT-5.2-Codex model, OpenAI's most capable coding model to date, launched less than two months ago.
CEO Sam Altman highlighted that while GPT-5.2-Codex is the strongest model for complex tasks, its new interface offers greater flexibility. Benchmarks show mixed results, with GPT-5.2 leading in command-line tasks but facing competition from other models in bug-fixing scenarios.
Features in the Codex app include background automations and customizable agent personalities. OpenAI emphasizes the app's potential to drastically accelerate software creation, with development speed limited only by user ideas.
