If you've ever tried to use AI image generation in a real creative workflow, you'll know this particular misery. You spend time tweaking your prompts, refining a character's look, and finally get what you were looking for. You then ask the tool to show her in a different pose… but get back someone who looks like a distant relative at best.
This has been one of the most stubborn practical limitations of generative AI, and it's the thing that's stopped it from being useful for anyone wanting to make client-ready mockups or storyboards for campaigns, animation, comics or any other visual discipline requiring continuity.
