My experience with Opus in the last weeks is the opposite. I have the feeling Opus got smarter since they released and blocked Fable. Maybe they got more compute available since a) they finished Training Mythos/Fable and b) couldn't provide inference for it?
Interesting that I have the exact opposite experience with Opus 4.8 being nearly unusable dumb in the past couple of days. I was trying to explain this as the new Sonnet release announcement may have overloaded their systems again, but let's see in a few days. Right now it hurts more to my workflow than helps.
