M3.1-Flash Max is running at around 116 t/s, and the agents now feel a lot more like the ones in Grok Bot, It’s been running my new benchmark for more than 50 minutes, and so far it genuinely feels like it’s performing at a frontier model level, My first impressions: it’s extremely fast, you can message the agents while they’re working without any issues, which is basically impossible in some other harnesses, and it also has a cloud mode that runs everything remotely without using your local memory, Really impressed so far, I’ll post the full results soon, including a complete comparison with other models

I've tested it also. It is fast, but kinda dumb. It overstates findings during PR. very average feelings.

being able to interrupt agents mid-run without breaking the harness is a huge usability win.

Doesn’t Claude code have seamless messaging while working? At least my experience with Opus 5.5 has been solid considering it basically sends all work to background agents

This is a killer insight. Thanks So it may all boil down to the output quality, then.
