Prompt Template Makes Qwen Image 2.1 Design Like Closed-Source Models

wjc_5 · reddit · 2026-09-28

A detailed workflow for Qwen Image 2.1: an external LLM first converts an image request into a structured prompt covering composition, hierarchy, typography, and layout — design decisions official T2I rewrite/I2I prompts don't make — before generation. Especially useful for posters and text-heavy designs.

Practical settings: 40 sampling steps is a sweet spot; 4.0–4.2 megapixels for text-free images, 2.0–2.5 MP for large-text posters (higher resolutions destabilize lettering), avoid below 2.0; no acceleration LoRA needed (may hurt quality), ComfyUI Kitchen helps speed.

Limitations: unstable hands/limbs; portrait aesthetics behind Z Image and Krea 2. Full tutorial on YouTube, resources in comments.
