Due to Claude Code responding with 500 for me at the moment, I decided to make an experiement and try to redo a few sessions that I started with Opus 4.6 in CC but with Opus 4.6 in Antigravity. tbh I expected responses would be pretty much the same, cause it’s the same model, but shockinly they weren’t. Those issues that Opus 4.6 in CC got completely right and suggested reasonable fix, Opus 4.6 in Antigravity completely misunderstood and suggested to fix symptoms instead of looking for a root cause. Which made me wonder if it’s a CC that just cooks Opus 4.6 better or what Antigravity sells as Opus 4.6 is actually a Sonnect 4.5 (that’s how it felt). P.S. unfortunately can’t share prompts/responses as they are work related, but it’s an easy experiment to try yourself. submitted by /u/kgoncharuk
