AI/ML API ran an experiment having Claude Fable 5.2 and GPT-6.1 Sol each recreate the Cars Piston Cup finale in 3D voxels. Fable 5.2 spent $108.87 versus GPT-6.1 Sol's $13.02 — an 8x gap.

The author argues the cost reflects extra work: Fable strictly sticks to voxels, making every puff of smoke actual geometry in every shot, while Sol doesn't. In the crash scene, Fable's flipping car is lit with readable paint, while Sol's is a dark silhouette. Both models are available via the aimlapi API.
