OpenAI has released a dedicated macOS application for its Codex AI coding tool, enhancing its capabilities to manage multiple AI agents for complex tasks. The app builds on Codex, which debuted last spring as a response to competitors like Anthropic's Claude Code. It introduces features like Skills and Automations to streamline workflows for developers.
OpenAI introduced the Codex macOS app on February 2, 2026, expanding access to its AI-powered coding assistant beyond command-line interfaces, web versions, and IDE extensions. Previously available since last spring, Codex began as a programming agent that generates code but has evolved to orchestrate multiple AI assistants working in parallel on intricate projects.
A key demonstration involved Codex creating a Mario Kart-like racing game, featuring selectable cars, eight tracks, and power-ups. "It took on the roles of designer, game developer and QA tester to validate its work by actually playing the game," OpenAI explained. The system delegated tasks, using GPT Image for visual assets while another model handled web game coding, showcasing how multi-agent collaboration tackles challenges beyond a single AI's scope.
The app includes a "Skills" section, which bundles instructions, resources, and scripts for reliable tool integration and workflow execution. Users can create and manage skills via a dedicated interface, explicitly requesting them or allowing automatic selection based on tasks. Additionally, the Automations feature enables scheduling repetitive jobs to run in the background. At OpenAI, this has been applied to tasks like daily issue triage, summarizing CI failures, generating release briefs, and bug checks.
Agents are organized by project, supporting multiple simultaneous efforts and worktrees to prevent conflicts. This launch positions OpenAI to catch up with Anthropic's Claude Code, which already offers a macOS version, amid broader industry experiments with multi-agent AI, such as Anysphere's Cursor building a web browser from scratch.
To boost adoption, OpenAI is doubling rate limits for Plus, Pro, Business, Enterprise, and Edu plans, while providing limited-time access to ChatGPT Free and Go users.
