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.
