The article compares the performance of various AI models, including GPT-5.6, Grok 4.5, Claude, and Muse Spark, on four different tasks: a raycaster, a Rubik's Cube, a calculator, and Game of Life. The results show that different models excel in different tasks, with GPT-5.6 Sol performing well on the raycaster and Claude Fable 5 doing well on the Rubik's Cube. The article also notes that open-weights models can perform well on simple tasks like Game of Life, but struggle with more complex tasks. The comparison highlights the strengths and weaknesses of each model and their potential uses.
