Fable 5.1 vs Opus 5: same-prompt 3D ocean test shows rain-drop detail, at 2x the price
socialwithaayan · x · 2026-09-02
Using the same one-shot prompt to build a 3D ocean POV sandbox, Fable 5.1 clearly outperformed Opus 5 — you can even see rain droplets in the ocean, with the scene described as GTA 5-level graphics. A follow-up test one-shotted a teleprompter app better than Elgato's.
Pricing: Fable 5.1 costs $10 input / $50 output / $0.25 cache — twice Opus 5's $5/$25 — but 50% cheaper on cache, which may make it cheaper for long working sessions. The author asks: does that make Fable 5.1 better overall for you?
