Hey Hunters! 👋

OpenAI just launched Codex, a cloud-based AI coding agent designed to handle complex software engineering tasks.

💡 Key Features:

✅ Multitasking: Write features, fix bugs, run tests, and propose pull requests—all in parallel.

✅ Integrated Environment: Each task runs in its own sandbox, preloaded with your codebase.

✅ Smart Guidance: Use AGENTS. md files to instruct Codex on navigating your project.

✅ Human-like Coding: Trained to mirror human coding styles and preferences.

Currently available to ChatGPT Pro, Team, and Enterprise users, with broader access coming soon.

Excited to see how Codex transforms your development workflow! 🚀

I am pretty curious how this will play out with the competitors (I mean OpenAI vs. Replit, Lovable and other pro-code oriented tools specifically designed for programming solutions).

This sounds incredibly powerful! I’m curious, how exactly do the AGENTS.md files work with Codex? Do they support dynamic updates to adjust guidance in real-time as the project evolves?
