I’m joining OpenAI Codex to work on the future of agentic development! At Cursor, I got to see the shift from autocomplete to agents. The next step isn’t a better IDE. It’s an Agent Development Environment (ADE): systems and tools for orchestrating agents, reasoning over their outputs, and making them autonomous enough to reliably complete ambitious work. After chatting with Alexander Embiricos and Tibo, it was clear that Codex is the best place to realize this vision. The team has consistently shipped SOTA models for agentic coding (check out gpt-5.3-codex) and I’m pumped for the future that the new Codex App points to. What I’m most excited about is the broader mission: accelerating the knowledge work economy. All agents are coding agents, and we’re already seeing Codex used across every job function within organizations. I’m extremely grateful for my time at Cursor, working with the incredible team, and I’m proud of what we built together. I’m excited to take an even bigger swing with Codex. If you’re curious to get a glimpse of where we are headed, download the Codex App! If you want to work on this mission, please apply or reach out - we are hiring across all functions! You can just build things.

Fun fact: we built slash commands into Cursor months ago and we forgot to tell anyone about it 😅 Try it out and let me know what you use it for! Also let me know if you uncover any other secret features in Cursor we should broadcast out 😬

The Datadog, Inc. MCP in Cursor is a magical experience. I prefer it as a way to diagnose issues, spin up dashboards, and gather data for retros. Use our Composer model and you will really feel like you're flying.

We just launched Sites into Codex! Software creation was always about more than writing code. Sites in Codex fundamentally gives the power of end-to-end software creation to every user, no matter their technical fluency. These Sites are fully deployed to a URL, private to workspaces, come with authentication, can have static files, and can store dynamic data in databases. It is in preview for business and enterprise teams and will be rolling out to all workspaces over the next day. Give it a try by typing @ Sites into Codex and ask it to build anything! This project took a massive amount of effort across hundreds of people at OpenAI - proud that we were able to get this out and excited to see what you all build with it!

We just launched Codex Security! Probably a no-brainer for most teams to turn on. Some things I'm excited about it: - Agentic security review leveraging our SOTA models - Always on codebase scanning - Detailed reports with code paths on vulnerabilities - Auto-fix any report with a PR Teams and enterprises can try it out through Codex web.

Knowing Codex is better for complex tasks makes me bullish on Chamath Palihapitiya and 8090 He points out that Codex is much better for meaty, large problems, while Claude feels good for more day to day work. We’re improving model personality so Codex feels even better for pair programming. But we think pair programming with agents is a local optimization. The longer term pattern is delegation. Most people just aren’t asking agents to do ambitious enough work. The people who are delegating use Codex.
