[Bug] Performance degradation after usage threshold suggests undisclosed rate limiting or model degradation

Bug Description
i've complained about anthropic/you completely nerfing the model after a certain usage point in a session/week. it is 100% clear that that threshold was just reached given the extreme dropoff in performance. if you want to fucking rate limit me, rate limit me. but don't fucking tell me im interacting with your most capable model when it is 100% clear a potato can think better than what it's putting out
