cat(@_catwu):One of the things I love about Claude Fable 5 is that it knew to use propensity score matching (matching users on activity so you compare like with like) in my retention analysis without me asking. It’s exciting to see Fable 5’s improved judgment across all of its work, from writing emails and docs in Cowork to debugging complex errors in Claude Code
