GPT-5.6, Grok 4.5, and Muse Spark Build Four Apps in Massive AI Showdown

GPT-5.6, Grok 4.5, Claude, and Muse Spark build the same 4 apps

We expanded our AI build-off to twelve models, including GPT-5.6 tiers, Grok 4.5, and Meta's Muse Spark, to generate four distinct applications. Addressing community feedback, we added open-weights models and ran five attempts per task to measure consistency. While GPT-5.6 dominated the raycaster task, Claude Fable 5 surprised us with a perfect Rubik's Cube solve, proving that performance varies wildly depending on the specific challenge.
