Naoki Urasawa Ideogram4 v1

LoRA (lokr) adapter trained on Ideogram 4 (ideogram-ai/ideogram-4-fp8) for a Naoki Urasawa style.

Prompt format

Ideogram 4 does not take a plain-text prompt. It expects a structured JSON prompt. This LoRA is activated by setting the style fields:

• style_description.art_style: Naoki Urasawa style
• style_description.medium: manga_page

Fill the rest of the JSON schema (high_level_description, style_description.aesthetics/lighting/color_palette, compositional_deconstruction) to describe the scene.
