Codex just got faster, more reliable, and better at real-time collaboration and tackling tasks independently anywhere you develop—whether via the terminal, IDE, web, or even your phone.
GPT-5 Codex is outperforming for me so far. It can handle both quick coding tasks and long, complex projects independently. It understands entire codebases, does good code reviews, and most importantly - adapts to your coding style (to what I've observed till now).
Impressed by OpenAI’s latest release! Codex feels faster, smarter, and truly helpful for coding tasks.
Congratulations! I'm really glad to see this product, it seems like it can help programmers improve their development efficiency!
Love how GPT balances power and ease of use; the [standout feature] makes my workflow smoother. Excited to see more!
Codex just leveled up faster, more reliable, and built for real-time collaboration across terminal, IDE, web, or even your phone. It tackles tasks independently, wherever you code. Dev flow stays smooth, no matter the surface.
Honestly, people should pay more attention to Codex. It already solves problems that others can’t, and now with the update, it feels even more reliable. Using it locally in VS Code is good for me, but I like that it works across so many environments.
I switched yesterday from Claude Code, which I absolutely loved, to Codex. I found CC to be incredibly frustrating of late. It really felt as though the model was being downgraded and often made mistakes that it never used to in the past. Which was bad for my blood pressure :). Anyway, super happy with Codex. It went on a tangent but with some feedback recovered remarkably well.
I think a lot of people are sleeping on codex. It solves issues in code where Claude sonnet 4 (in both windsurf and cursor) cannot—and that was before the GPT-5 update. You can run it in the cloud via your GitHub report, which is a great workflow, but there’s also a VS Code extension, which I personally use in Windsurf, that can run on local code.
Great to see this product evolve. Constantly looking for ways to improve my agentic flow from PRD creation to code to tests. Would love to understand OpenAI vision for the overall product development pipeline!
