How do I get an AI image generator to create consistent characters across multiple images?

Getting an AI to draw the same character twice is genuinely tricky. It's like asking an artist with a fantastic imagination but a terrible memory. The core challenge is that most image generators treat each prompt as a brand new world. They don't have a built-in 'character sheet' memory. But you can fake it. The most reliable method is to use a generator that allows a 'seed' number. A seed is just a starting point for the AI's random pattern. If you find an image you like, grab its seed number. Use that same seed in your next prompt, along with an extremely detailed description of your character. Think of a police sketch artist description, not a novel. Don't just say 'a happy woman.' Say 'a woman with sharp cheekbones, a small nose stud on her left nostril, shoulder-length curly auburn hair, and round wire-rimmed glasses.' You must copy-paste this exact description into every new prompt. Even then, it's not perfect. You'll often get a character who looks like a close sibling, not an identical twin. A concrete example: in Midjourney, you'd first generate an image with the prompt 'a woman with sharp cheekbones, a small nose stud, curly auburn hair, wire-rimmed glasses, standing in a coffee shop --ar 3:2'. You get an image you love. You react with an envelope emoji to get its seed number. Your next prompt would be 'a woman with sharp cheekbones, a small nose stud, curly auburn hair, wire-rimmed glasses, fighting a dragon --seed 123456789 --ar 3:2'. A pro tip: the background matters. If your character always stands in a coffee shop, the AI learns to associate 'coffee shop' with the face. Change the setting dramatically in the second prompt to force the AI to focus on the character description itself, not the scene.
