GPT-5.6 Sol Ultra Outperforms Claude In Game-Dev
Simon Willison used GPT-5.6 Sol Ultra to build a fully functional game called Moonlight & Mayhem. The model leveraged aggressive sub-agent workflows to surpass Claude Fable 5's previous attempt at the same prompt. It generated the code, textures, and prompts autonomously. This demonstrates the tangible coding advantage of multi-agent architectures over single-model generation.
