Fable 5.2 wasted 12 hours on a nonexistent main-thread GPU constraint before admitting it
gandamu_ml · x · 2026-11-11
A user shows Fable 5.2 can be dumb too: the model insisted it had to do GPU resource prep on the main thread and spent about 12 hours working around that nonexistent constraint. Only after sustained pushback did it admit no such prep was needed, forcing a redo — a reminder that new models still lock onto wrong assumptions without human correction.
