Opus 5.5 Rumored Cheaper to Serve Than Opus 5 While Matching Fable at Coding
haider1 · x · 2026-10-23
Per this unverified take, Opus 5.5 is cheaper to serve than Opus 5 and can match or beat Fable at coding with less compute, so more users are shifting to the smaller model. If Fable 5.5 lives up to rumors, Anthropic could serve even more users with less compute, easing its capacity constraints.
