Sonnet 5.5 costs more than Opus 5.5 but is far less token-efficient, Reddit user warns
Conscious_Warrior · reddit · 2026-09-29
A Reddit user argues Anthropic's Sonnet 5.5 is priced the same as (or higher than) the stronger Opus 5.5 and equal to Fable 5.1, despite being weaker.
The key issue is token efficiency: Sonnet 5.5 burns far more tokens for the same tasks, inflating real costs. The author's advice: stick with Opus 5.5. (Third-party claim, unverified.)
