Frankly after testing out Fable last week, it was just a bigger sink of tokens than anything else. The amount of tokens consumed by it wasn't worth the steps it saved me compared to using opus 4.8.

As much as I hate to say this, I think it is an user error. Fable is very to the point, much more so than any other Anthropic model. I found it to be cheaper to use Fable, than using Opus for same task, but in order to achieve that, it needs to be given a targeted task.
