This comes up from time to time and although my experience is anecdotal, I see clear degradation of output when I run heavy loads (100s of batched/chunked requests, via an automated pipeline) and sometimes the difference in quality is absolutely laughable in how poor it is. This gets worse for me as I get closer to my (hourly, weekly) limits. I am Claude Max subscriber. There’s some shady stuff going on in the background, for sure, from my perspective and experience during my year or so of intense usage.
