I have yet to run into a project where I felt like I needed this and was worth justifying the latent worry about it disappearing or micromanaging quota usage. Heard about massive refactors or ports that were compressed into days but I'm wondering if it's really worth the inference cost.

funnily enough for me, Fable 5 was much better at refactoring my large codebase than Opus 4.8 was - perhaps the scope of Fable is very great
