Claude Opus 5 wins LLM tower-building physics simulation benchmark

A user benchmarked ten large language models on their ability to construct towers in a physics simulation, with Anthropic's Claude Opus 5 emerging as the winner. The benchmark involved placing blocks via a tool API, with noise introduced for precision in position or velocity. Claude Opus 5 achieved the highest standing height by strategically ending attempts to preserve tall structures, outperforming models like GPT-5.5 and DeepSeek V4 Flash. AI
