[Opus 5 Defeats Fable 5 in 3D Physics Simulation Test, Costs Halved] Deep Tide TechFlow reports that on July 25, Opus 5 achieved a decisive victory over Fable 5 in a 3D destruction physics simulation task, with costs amounting to only half of the latter. The test required four models to construct three realistic physical scenarios using HTML: a tornado, a wrecking ball demolishing a building, and a truck collapsing a bridge. Opus 5 completed all tasks correctly, while Fable 5's tornado barely managed to lift objects, and its building collapsed before the ball made contact. Opus 5 incurred a cost of $1.40, while Fable 5 cost $2.82. Kimi K3 and GPT 5.6 both failed the test.
