Personally, I was not impacted Monday and most of Tuesday. Now since yesterday I cannot run a single prompt without eating my entire 5 hour window. I'm talking an identical prompt on an identical repo state from something I ran Saturday that only spent ~5% usage max then, now eats my entire 5-hour window. Switching to Sonnet doesn't even help...
Yes, it's been insane. Hitting limits by noon since late last week. Not even using opus 4.6 with 1mm context, just normal opus and a bit of sonnet/haiku.
