I have reduced usage of Fable and Sonnet 5 to a minimum. Fable in particular is amazing at creative tasks, but not worth the cost for almost everything else. I can have Opus 4.6/4.7 running non-stop without hitting quota, vs maybe 20 minutes of Fable usage.
Fable can solve the problems Opus couldn't. BUT most of the time I'm not having those kinds of problems.
I wouldn't say I'm doing anything groundbreaking but definitely at times obscure and that's when Fable has been able to dig me out of the rut. (the alternative I was actually following was reading textbooks myself to understand the domain better)
Well, I both agree and disagree with you.
On one hand, the price is just astronomical for Fable, well, not exactly astronomical, but I would say unaffordable. That is to say, so expensive that it is impossible to use.
But on the other hand, Fable is simply incomparable to anything else. I mean, it is just amazing. There is nothing even close to being equal to it.
After getting used to Opus 4.8, Sonnet 5 is nigh unusable for coding. I much prefer Opus 4.8 + DS V4F for routing. Sonnet 5 is just not useful in the price/performance anywhere. I still get some use of Fable for planning because it can comprehend agent-built codebases (which have repetition of local patterns to a grand degree).
