Ethan Mollick tests the Flux 3 video model using surreal, cross-genre prompts.

Flux 3 is pretty darn impressive. This is what it produced with the prompt: "tracking shot that follows a female astronaut with her helmet open as she walks through a regency dance in a traditional manor, with a mural on the wall painted by Rothko. Pushing people out of the way to make room..." 1/2

Ethan Mollick critiques overly dramatic prose styles in certain frontier models during straightforward tasks.

Fable is amazing but needs to stop talking like someone who has read only pulp fantasy: "I have shown you the way but you must open the door. The map exists but the path is yours. The atlas of your instinct — every fact must first know itself" Please, just make the infographic about cheese I wanted

Ethan Mollick humorously documents an LLM agent swarm analyzing a simple cheese infographic with extreme technical seriousness.

Here is the cheese infographic: how-to-read-a-cheese.netlify.app "One consequence worth noting: the chart panel stays cave-dark in both light and dark themes, because fresh cheese is white and white has no contrast on a pale ground — the light-mode ramp failed the contrast floor" Thanks, Fable.
