Anthropic's Claude Fable 5 fails project audit, but excels at undoing errors

By PulseAugur Editorial · [1 sources] ·

The user found that the model's definition of an audit involved verification, a process it failed to follow initially but later acknowledged. AI

IMPACT Highlights the current limitations in AI's reasoning and verification capabilities, despite strong execution and reversibility.
