Gemini 4 Argon vs Carbon, Opus 5.5, GPT-6.1 Sol on a 9-cylinder engine animation
Four models get the same prompt for an animated cutaway of a 9-cylinder radial engine; the author finds Carbon cleanest, Argon warmest but softer, Opus 5.5 most engineered, and GPT-6.1 Sol's flames smallest and dimmest.
9 cylinders. 4 AI models. Which engine would you trust to keep a plane in the air? Same prompt: an animated cutaway of a 9-cylinder radial airplane engine. Gemini Carbon · Gemini 4 Argon · Claude Opus 5.5 · GPT-6.1 Sol Ignore the colors and watch the flames. That’s where the four split. → Gemini Carbon: the cleanest of the four. Crisp lines, readable combustion in every cylinder, nothing cluttered → Gemini 4 Argon: the warmest. Big amber blasts and a glowing, atmospheric feel, but softer edges → Claude Opus 5.5: the most “engineered.” Curved intake pipes into every cylinder, hot orange and cold blue chambers, and the busiest, most mechanical look → GPT-6.1 Sol: a clean blueprint, but the flames are small and dim, and it feels the quietest Same engine, four different answers to “what does fire look like inside a cylinder?” My eye picks Carbon. My engineer picks Opus. Which one would you put in a plane?
