Fable 5.2 is 20% cheaper per token. Per GDPx task, SemiAnalysis paid $88.15, up from $67.16. Where 5.1 tried about 20 test cases, 5.2 sometimes wrote hundreds or thousands. That bought first place at 16.4%. Maybe worth it, but the per-task number is the price.

Sticker cut and roadshow, same Monday. $8/$40 reads well to investors. The subscription side reads tighter: one log analysis has a $200 Ultra plan buying about $15,000/month of Opus 5.5 but only about $3,000 of Fable 5.2.

Items that move per-task cost: five effort levels, Medium is the default in the Claude apps and Claude Code. Cursor says levels behave differently from 5.1, start at default. Cache reads $0.20, writes $10 or $16 by TTL.
