Character Consistency in the Age of the Flux Dev Model
A working note on why character consistency is less about a single prompt and more about references, constraints, iteration, and the pipeline around the model.

The public site already points at the problem: character consistency is the real test of an AI image or video workflow. A single strong frame is easy to admire. A character who survives a campaign, a cut, a pose change, and a new lighting setup is a different standard.
The practical lesson is that consistency does not live in the prompt alone. It lives in reference discipline, seed control, model choice, image-to-image passes, ControlNet-style constraints, LoRA or product-model work where the brief justifies it, and a final edit pass that treats the generated material like footage rather than magic.
That is the useful difference between prompting and directing.
Prompting asks for an image. Directing builds the conditions under which a body, product, face, room, or texture can keep its identity across multiple outputs.
For the studio's work, this is becoming the core craft: not one beautiful generated still, but a repeatable visual system that can support story, product, and campaign material without collapsing into a new character every time the shot changes.
