What they actually direct
Look books used to travel as PDFs. Now they have to travel as bibles pasted into every generation, because the model will invent a new movie in the next frame. The AI Art Director writes that bible: hour, materials, light signature, prohibitions (“no porcelain skin,” “no marble,” “no fairy lights”).
They plan still coverage — distance, gesture, insert — and they kill beauty that breaks continuity. A perfect face on a different hour is not a win. It is a new cast.
Where the job stops
If the assignment is a spot, someone has to own seconds and sound. If it is a product, someone has to own the rite and the definition of done. Art direction can serve those, it cannot replace them. Career templates that draw a straight line “AI Art Director → AI Creative Director” are describing seniority plus scope, not a rename.
Portfolio test
A grid of pretty stills with no brief is operator work. A sequence with a locked hour, a named negative, and a death log is art direction. Hiring managers can tell in under a minute which one they were sent.
