Codex App Update Adds Support for Copilot, Cursor, and Grok Models
The Codex app has released a new update that introduces integration and support for Copilot, Cursor, and Grok models. This update allows developers to use a wider variety of AI coding assistants and LLMs directly within the Codex ecosystem, enhancing workflow flexibility. The integration brings models from external platforms like GitHub Copilot, the Cursor AI editor, and xAI's Grok into the Codex desktop application environment.
## BACKGROUND
OpenAI launched the Codex app for macOS in March 2026 as a dedicated desktop command center for AI-assisted software engineering and parallel workflows. Cursor is a highly valued AI-powered code editor, while Copilot and Grok are widely used AI tools developed by GitHub and xAI respectively.
