Obsessive is the right word. Over the weekend I had to stop it multiple times deep into a multi-hour long turn to ask what the hell it was doing. It was like a dog with a bone and would NOT let go of its current work to talk to me. I had to interrupt it three times with increasingly aggressive instructions to STOP and answer my questions before proceeding. In another session it straight up told me it was in the middle of debugging something important and to ask later.

I'm running an RTX 6000 Blackwell. It regularly spent over an hour per turn thinking. Every time I looked at it, the thinking trace seemed coherent, sensible, appropriate. But it could never settle on a solution.

Granted, I was trying to have it solve a hard problem that 5.6 Sol couldn't solve, but still.

Either way, I'm still impressed. It genuinely feels better than Sonnet 5
