Fable 5.2 cost curve: Xhigh tops at ~$15/task, Max spends more and scores lower
zainhas · x · 2026-11-10
Following Fable 5.2's release, dev zainhas flags its "pay to lose" pricing with a FrontierCode 2.0 score-vs-cost chart across effort levels: Fable 5.2 peaks at 49.5% on Xhigh ($15/task) but drops at Max ($50/task); it trades wins with Opus 5.5 at low-mid tiers, while GPT-6 Astra and Gemini 4 Carbon trail. Med-high looks like the sensible default — higher effort can cost more without scoring better.
