alt Hacker News> I've been not just unimpressed by Fable, but actively find it to generate negative value.
Fable is good in a few very specific domains (graphics programming) but otherwise it's an overhyped model. Far too expensive too. Opus 5 is outright better in every metric.
I honestly find Opus 5 a downgrade too. It's not as bad as fable, but nearly so, and is very argumentative. It'll straight up ignore directives and design decisions.
