Getting on and off fable this week has been quite interesting. For my personal work stream (big terraform monorepo, hundreds of states) I’ve using mostly superpowers to do heavy / quality work. But with fable, I tried just telling it what to do, and it produced roughly the same results without a big structured back and forth that I was accustomed to. Then after using up all my fable allowance I figured let’s see if o…
This is an interesting comment because it makes me want to ask the question, what is the use for fable then? For me, GPT 5.4 is enough when using recursive-mode. I do appreciate GPT 5.5 Pro for some larger research, architecture, planning tasks though. I think that's what Fable is for. A very small % of total work.
That seems valid in today's world. Right now it's expensive, slow, and accurate. I imagine in the fairly near future it will be cheap, slow, and accurate, and that'll be a great opportunity to let it run on anything time-insensitive.
Re current use-cases: in addition to planning, there's also some tasks which Opus just can't complete but Fable can. Multiple times I've spent hours in combination w/ Opus trying to debug some particularly nasty nondeterministic issue, only to have Fable nail it in 20mins while I walk the dog.
