I haven’t, but I’ve used Opus in Antigravity and it performs pretty much the same? It’s hard to tell minute differences.

Do you think Claude Code is what makes their models operate better?

And by the same token, then what would give Gemini a fair run? Because the Gemini chat app, Stitch, and the CLI are all things I’ve used and the model can’t help itself from a) saying it’s done when it isn’t; b) going off-rails; c) ignoring strict instructions after a while.
