OpenAI has introduced a new macOS application for Codex, marking a significant step in its push into agentic coding workflows. The app integrates parallel multi-agent capabilities and advanced automation features designed to streamline AI-assisted software development.
The release builds on Codex’s earlier launches as a command-line tool and later a web interface. The macOS version brings together agent skills and state-of-the-art workflows in a more flexible desktop environment aimed at developers working on complex projects.
The launch follows the recent debut of GPT-5.2-Codex, OpenAI’s most advanced coding model to date. Chief Executive Officer Sam Altman said the new interface is intended to make the model’s advanced capabilities easier to use in real-world development scenarios.
The macOS app supports multiple AI agents operating in parallel and introduces background automations that can run on a scheduled basis. Tasks completed by agents are queued for review, enabling asynchronous workflows. Users can also customise agent behaviour by selecting personality styles ranging from pragmatic to empathetic.

Benchmark comparisons show GPT-5.2-Codex performs competitively against rival systems, including models from Anthropic and Google. While results vary depending on the benchmark and use case, OpenAI is positioning Codex as a high-performance option for agentic development environments.
OpenAI said the broader goal is to accelerate software creation by reducing friction between idea generation and execution. The company believes that AI-assisted development tools can significantly shorten build cycles, allowing developers to create sophisticated applications in a fraction of the time required by traditional approaches.
