OpenAI brings its Codex coding app to Mac, with new multi-agent abilities included

OpenAI has released a dedicated macOS app for its Codex coding agent, which enhances its capabilities by allowing it to manage multiple AI assistants to complete complex tasks. Initially launched in spring, Codex is designed to write code for users, but the new features enable it to delegate tasks to different models with complementary abilities. An example provided by OpenAI illustrates this functionality through the creation of a Mario Kart-like racing game, where Codex utilized GPT Image for visual assets while coordinating other models for different aspects of the game development. In addition to OpenAI's advancements, Apple has integrated OpenAI's Codex and Anthropic's Claude Agent into its Xcode development environment with the release of Xcode 26.3. This update allows developers to utilize these AI-powered coding agents not only for assistance but also to actively write and edit code, update project settings, and search documentation within the app. Previously, Claude and ChatGPT were available in Xcode, but the latest update enhances their functionality by enabling them to take action directly within the application. The evolution of Xcode reflects a broader trend in software development towards fostering creativity and collaboration, often referred to as "vibe coding." This shift indicates a growing demand for development environments that support diverse coding styles and workflows, making programming more accessible. The emphasis on creativity alongside technical proficiency suggests a cultural movement within the tech community, indicating that future software development will prioritize artistic expression as well as functionality. Overall, the integration of AI agents into Xcode and the advancements in OpenAI's Codex signify significant developments in the coding landscape, enhancing the tools available to developers and promoting a more inclusive approach to software creation. These changes are part of a larger transformation in technology that aims to democratize access to complex coding tools, allowing a wider range of individuals to engage in programming.
