In this video, we put four of the most advanced large language models available today into a full head-to-head comparison. Our contenders are GPT-5.2, Claude Opus 4.5, Gemini 3 Pro, and Grok 4.1.

We run each model through a wide range of demanding, real-world tests designed to stress reasoning ability, coding skill, multimodal understanding, creativity, behavioral consistency, and iterative improvement. These include browser-based OS tasks, game and simulation generation, image-to-website conversion, customer assistance scenarios, storytelling, and more.

This video provides a comprehensive breakdown of where each model excels, where they struggle, and how they compare across multiple domains when pushed beyond simple benchmark-style prompts.
