petergostev shares Claude Fable 5.2's BullshitBench results: refusals are way down — Fable 5 declined 1/3 of prompts, 5.2 nearly none — but performance dropped notably, ranking 40th (Max reasoning, 67.3% clear) and 53rd (Low, 63.3%), where Fable/Opus previously dominated the Top 10, suggesting a trade-off between fewer refusals and bullshit detection.
