What You Asked Claude to Do

stop making it unusable and dumb please respect your customers

we know when requests are throttled with overallonged "dumbing time" and inference time is reduced

please restore acceptable performance, at this point i've been writing code myself in the last 2 days and achieved more

it's a joke and a disgrace at this point

if you can't serve 4.8, just say that we are being served claude 3.5 currently, and so i don't launch it, so that he destroy a repo, and then i have to do all everything by hand for hours.

it is so bad i can't even write this issue with claude

thanks
