@wheremyai: Did you fall for it? #ai #aivideo #minimax #h3 #hailuo For over a year and a half, AI researcher Justine Moore (@venturetwins) has been testing every major video model with the exact same simple prompt: “man writes ‘hi’ in chalk on blackboard” Sounds easy, right? A toddler can do it. But almost every AI video model completely fails at it. Here’s what usually happens:
• The letters just magically appear without the chalk ever touching the board
• The hand moves but the writing is completely wrong or random scribbles
• The chalk floats an inch away from the surface
• The letters glitch, morph, or disappear mid-stroke
• Physics break and the whole thing looks cursed Even the best models (Veo, Sora, Kling, Runway, earlier Hailuo versions) got close but never fully succeeded. It became this unofficial stress test for whether AI video models actually understand fine motor control, tool use, physics, and continuous text generation. Then in August 2026… MiniMax 3 from the Hailuo AI team finally did it. Clean hand movements. Proper chalk contact. Actual legible “Hi” being written stroke by stroke. And the model is open source. This isn’t just a fun party trick. It shows real progress in: • Temporal consistency • Object interaction & contact physics • Text rendering inside video • Overall “world understanding” of everyday human actions AI video has gotten insanely good at looking pretty, but tasks that require precise sequential control like writing, drawing, or complex tool use still expose the gaps. This chalkboard test is one of the clearest ways to see how far we’ve come and how far we still have to go. Have you tried this prompt yourself? Drop the results in the comments, I need to see the fails 💀💀
