OpenAI has rolled out powerful new features to its Codex coding assistant, making it an even stronger partner for developers. The updates, now available through ChatGPT plans, include an IDE extension, GitHub code reviews, cloud-to-local task handoff, and a redesigned command-line interface (CLI).
“Codex now runs in your IDE,” the OpenAI Developers team announced on X, highlighting support for Visual Studio Code, Cursor, and other forks — one of the most requested features from the community. Developers can now seamlessly move coding tasks between the cloud and local environments without losing context. “Kick off new tasks, delegate in-progress work and review results without leaving your editor. Then continue tasks from the Codex web in your IDE to keep building locally,” the company explained.
For GitHub users, Codex introduces automatic pull request reviews that go beyond static analysis. According to OpenAI, the system “checks a PR against its intent, reasons across the codebase and dependencies, and can run code to validate the behaviour of changes.” Developers can configure Codex to auto-review new pull requests or summon it as needed.
The Codex CLI has also been completely rebuilt to harness GPT-5’s agentic coding capabilities, featuring a modern terminal interface, image inputs, message queuing, approval modes, to-do lists, and web search. OpenAI said these enhancements aim to make Codex a more effective collaborator across workflows — from local development to code review and deployment.
