$200 plan and VERY tame usage (not 24/7, not every day even, maybe 8-10 hours for ~4 days). Suddenly I am at 96% weekly (!) limit, multiple session limits, two daily limits.

Either they decimated the limits internally, or they broke something.

Tried all the third-party tricks (headroom, etc.), switched to 200k context window, switched back to 4.5.

I hope 4.5 will help, but the rest of the efforts didn’t move the needle much
