Together with 3.7 Sonnet. And the claim was that it is rapidly gaining ground, not that it sparked initial interest. I still don’t see much proof of adoption. This is actually the first I’ve heard about anyone actually actively using it since its launch.

I've been reaching for Claude Code first for the last couple weeks. They had offered me a $40 credit after I tried it and didn't really use it, maybe 6 weeks ago, but since I've been using it a lot. I've spent that credit and another $30, and it's REALLY good. One thing I like about Claude Code is you can "/init" and it will create a "CLAUDE.md" that saves off it's understanding of the code, and then you can modify it to give it some working knowledge.
I've also tried Codex with OpenAI and o4-mini, and it works very well too, though I have had it crash on me which claude has not.
I did try Codex with Gemini 2.5 Pro Preview, but it is really weird. It seems to not be able to do any editing, it'll say "You need to make these edits to this file (and describe high level fixes) and then come back when you're done and I'll tell you the edits to do to this other file." So that integration doesn't seem to be complete. I had high hopes because of the reviews of the new 2.5 Pro.
I also tried some claude-like use in the AI panel in Zed yesterday, and made a lot of good progress, it seemed to work pretty well, but then at some point it zeroed out a couple files. I think I might have reached a token limit, it was saying "110K out of 200K" but then something else said "120K" and I wonder if that confused it. With Codex you can compact the history, I didn't see that in Zed. Then at some point my Zed switched from editing to needing me to accept every change. I used nearly the entire trial Zed allowance yesterday asking it to impelement a Galaga-inspired game, with varying success.
