804-Page Manhua on One RTX 4080: Reverse-Engineering gpt-image's Whole-Page Generation
Sensitive-Wealth5801 · reddit · 2026-09-07
A creator producing an 804-page manhwa recap comic locally (7 recurring characters, RTX 4080 16GB, ComfyUI) shows via embedded C2PA metadata that reference pages came from OpenAI's gpt-image API generated as whole pages in one pass. He details his SDXL + ControlNet pipeline, exact failure modes (identity drift, ignored OpenPose skeletons, fused figures, eye deformations, broken weapon mechanics), the profile-view skeleton fix, and asks whether whole-page local generation is possible — comparing SDXL, FLUX.2, Z-Image Turbo, Qwen-Image-Edit, DreamO and paid APIs for character consistency at 16GB VRAM.
