Dual-subscriber comparison: OpenAI's Sol rivals Opus, not Fable

DynaBeast · reddit · 2026-09-01

A heavy work user paying for both ChatGPT Pro and Claude Max pushes back on claims that Sol is near Fable's level. In their view, OpenAI's flagship 5.6 Sol is really a competitor to Opus 5: similar price and output quality, but different failure modes—Sol takes shortcuts and misses edge cases, while Opus over-expands and needs reminders to focus.

Across every task, Fable consistently takes the least time, fewest tokens, and needs the fewest prompt warnings and corrections. Expensive and quick to burn weekly limits, but 'it just works'—which the poster says neither Opus nor Sol achieves.
