beamnxw ./(@beamnxw):Claude Fable 5 was tested against Opus 4.8 on physics simulation tasks Both models received the same prompts and were tasked with generating standalone HTML5 simulations without using third-party libraries: → Chaotic double pendulum → Galton board → Water in a rotating drum (WCSPH) Generation costs: • Fable 5 - $3.35, 68.7k tokens, 14 min 47 sec • Opus 4.8 - $0.93, 38.9k tokens, 8 min 10 sec Fable demonstrated its most notable advantage in the water simulation. The model created a more cohesive and stable fluid volume Opus exhibited large gaps near the walls, with individual particles scattering across the scene, and the fluid itself was less stable
