SEO · x · 2026-11-10
The author shares CursorBench 4.0 results for Fable 5.2 across reasoning-effort levels, concluding that the HIGH setting is the best cost/benefit balance:
- High effort (default): 56.9% score at an average cost of $9.70 per task
- Max: peaks near 58.6% but jumps to $32+ — only worth it for especially complex plans
- Mid: 55.4% at roughly $16
The chart places Fable 5.2's High setting in the same score band (55%) as Gemini 4 Argon, Opus 5.5, and Sonnet 5.5, though those competitors cluster in the $0–$4 cost range; other models like Grok 4.7, GPT-5.6 Sol, Haiku 5.5, and Muse Wonder occupy lower cost/score tiers.
