Seeing a lot of people in here say that they need Fable for the tasks they're doing and Opus just isn't enough. My experience could not be more different. I seriously feel like Opus-level performance is totally adequate for most of my use cases, if not all of them. And it's probably been this way since, like, realistically, Opus 4.6. On the other hand, Fable I've observed getting into verification loops that just burned so much of my token budget. Combined with the higher cost of tokens from Fable to begin with, I just pretty much never use it for anything.
