Four models build a lobe pump from one prompt: Opus 5.5, Astra, Grok 4.7, Gemini 4 Argon
The same prompt asks four models to animate a two-rotor lobe pump whose rotors must mesh exactly; the author scores nothing and asks viewers which one actually pumps.
look f*cking closer. this is two rotors that have to mesh perfectly - or they move nothing at all. four models, same prompt, same machine: Claude Opus 5.5 · GPT-6 Astra · Grok 4.7 · Gemini 4 Argon a lobe pump has nowhere to hide. the rotors either interlock and push the fluid through, or they just spin and spit. some of these look tight. some are two shapes turning in a box. I didn’t touch a thing and I’m not scoring them. you tell me: which one’s actually pumping, and which one just animated? Opus, Astra, Grok or Gemini?
