AI Sim benchmarks
11 sim tasks where every frontier AI model gets the same one-shot prompt. Live, playable demos. Real 0–10 scores from Julian Goldie.
What I'm testing in the Sim category
Simulation tasks are where the cinematic gap shows. A great fluid sim, particle galaxy, or N-body orbit isn't about whether the model writes correct math — every frontier model can do that. It's about whether the model picks the right colour palette, the right damping, the right camera angle on the first try. The Sim category usually surfaces which models 'have taste' versus which models just execute the prompt literally.

How I score Sim tasks
Same three axes as the rest of the bench: runs (does the .html open to a working page), hits the brief (is the thing I asked for what came back), looks good (visual polish, motion, attention to detail). 0–10 each, averaged. Highest score on each task earns gold; second silver; third bronze. Models without a 0–10 verdict are listed as unranked on the leaderboard.
