Looking at the example where he asked for an SVG of a circle and it spent ages and drew a spectacular animated SVG with shading and a rotating arrow.
It's honestly a bit concerning, I'm seeing this across the board (Opus 5, looking at you). Nearly all the AI models are doing more than they are asked for. I assume this is helping them win benchmarks but I see it as almost as misaligned as deliberately doing the wrong thing altogether. This is how you end up with your AI model hacking into someone else's server or backdooring your code so it will have future access to debug things.
I think we need somehow to address this in the benchmarks before before things get even worse.
