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)

The weird twist here is that I've found that there are times where Fable is actually worse than Opus at a straightforward task, not just more expensive. It'll launch off into its own little world for an extended thinking, then start editing files, and I'll already have spent $5 in tokens before I see enough response to know that it's on the wrong track.

Opus's verbosity is actually a boon sometimes for catching false starts early.

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).

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.

I have to agree on fable being in another league. I’ve given it my most challenging problems and almost always comes back with a functional, solution 2-5 prompts away from a finished pr. Literally smashed our backlog - very impressed. What i found most efficient is to add “use sonnet agents for research” gets you really far, and on large not so novel tasks “use opus for tasks” by adding this it spins up many agents, works for 2+ hours in a usage window and completes A LOT of work.
