Z_Image Basic Alchemy Explanation

A complete step-by-step guide to training custom LoRA models for Z-Image Turbo — the ultra-fast 6B parameter model that generates images in just 9 seconds. Learn the entire workflow from dataset preparation to the critical model conversion step that ensures ComfyUI compatibility.

Product Type: Digital Tutorial (HTML + Markdown)

Why Z-Image Turbo?
- Ultra-fast inference: 9-second image generation (vs 30+ seconds for Flux)
- Lower VRAM requirements: Runs on 12GB GPUs with optimization
- Photorealistic quality: Excellent results for portraits and realistic scenes
- LoRA compatible: Train custom characters, styles, and concepts

Tutorial Structure (6 Chapters):

【Chapter 1: Environment & Hardware】
