Codex Can Now Code Alone for 7 Hours. What Would You Build?

OpenAI has released big improvements to Codex, making it a smarter and more reliable coding partner:

🔹 Codex CLI – Rebuilt with community feedback. You can now share images like diagrams and wireframes, track progress with to-do lists, and connect to external tools.

🔹 IDE Extension – Codex works directly inside editors like VS Code and Cursor, giving faster, smarter help based on your open files and selected code.

🔹 Codex Cloud – Tasks now run up to 90% faster, with automatic environment setup and even browser previews of what Codex builds.

🔹 Code Review – Codex can review GitHub pull requests, flag issues early, and even suggest or apply fixes.

💡 Codex can also work independently for up to 7 hours, iterating and solving tasks without constant supervision.

👉 Are you building something with Codex? I’d love to hear what projects others are creating.
