Strictly worse than Claude Code presently, but I hope since it's open source that changes quickly.

Given that Claude Code only works with Sonnet 3.7 which has severe limitations, how can it be "strictly worse"?

Whatever Claude Code is doing in the client/prompting is making much better use of 3.7 than any other client I'm using that also uses 3.7. This is especially true for when you bump up against context limits; it can successfully resume with a context reset about 90% of the time. MCP Commander [0] was built almost 100% using Claude Code and pretty light intervention. I immediately felt the difference in friction when using Codex.

I also spent a couple hours picking apart Codex with the goal of adding Sonnet 3.7 support (almost there). The actual agent loop they're using is very simple. Not to say that's a bad thing, but they're offloading all planning and workflow execution to the agent itself. That's probably the right end state to shoot for long-term, but given the current state of these models I've had much better success offloading task tracking to some other thing - even if that thing is just a markdown checklist. (I wrote about my experience [1] building AI Agents last year.)
