@mitchellh We found Fable to be the only model that found a cause of a front-end memory leak
Good stuff: we launched Fable 5 on a real memory leak ticket alongside GPT-5.5 and Opus 4.8 (a total of 5 agents in one click).
Fable was the ONLY ONE that found the root cause: an event listener dependency holding refs to replaced DOM nodes.
Red before. Green after. Hell yeah.
