Same prompt head-to-head: Fable 5.2 costs 76% more than Opus 5.5 but finishes 1h15m faster

A developer ran the same prompt through Claude Fable 5.2 and Claude Opus 5.5 to build an "Ice Cathedral" scene:
- Fable 5.2: $81.10, finished in 1h 56m
- Opus 5.5: $45.97, finished in 3h 11m
Fable cost 76% more but was 1h 15m faster, with noticeably richer detail in the ice, ship, and whale — trading higher cost for better quality and speed.
