Overview

This is a multi-phase Z-Image Turbo workflow designed to extract maximum detail, edge fidelity, and material realism on 12GB VRAM GPUs. This workflow also includes seed variance to the conditioning so that outputs with the same prompt have more variety similarly to SDXL, Pony, IL models. (Each photo pair in the showcase gallery is the exact same prompt) This workflow uses controlled sigma shaping, Res-2 samplers, and phased refinement passes to stabilize detail while avoiding common ZIT artifacts like:

Over-etched hair
Shimmering edges
Checkerboard blockiness
CFG-induced harshness

The result is clean, high-contrast outputs that scale well across portraits, fashion, cinematic scenes, and hard-surface material tests.

Key Features

Detail Daemon Sigma Control

Custom sigma curve shaping via Detail Daemon Graph + Sampler
Prevents early over-sharpening
Preserves skin gradients while locking edges late in the pass

Low-CFG Stability (3.0 Primary Pass)

Primary generation operates at CFG ≈ 1.0 - 3.0
Keeps ZIT from “fighting” the prompt
Enables natural lighting and material response

Phase 1: Base structure & composition
Phase 2: Detail reinforcement (carefully bounded)
Phase 3: Edge cleanup + block smoothing
Phase 4: Final polish, contrast, and optional desaturation

Includes side-by-side phase comparison nodes for tuning and learning.

Res-2 Sampler Focus

Res-2 (beta) chosen over DPM++ for:
- Cleaner hair behavior
- Reduced sparkle artifacts
- Better late-stage convergence
DPM++ intentionally avoided due to aggressive micro-contrast amplification

SeedVariance

Optional Seed Variance Node for:
- Diverse outputs using the same prompt
- Sliders control variance percent & strength

VRAM-Aware Cleanup

CacheCleaner + Easy-Use GPU cleanup nodes included
Designed for long batch sessions
Prevents silent VRAM creep during multi-phase runs

Hardware Target

12GB VRAM GPUs (RTX 3060 / 4070 / 5070 class)
Not designed for 8GB cards without modification or disabling of phases
Scales upward cleanly on 16GB+ systems

Recommended Usage

Portraits & fashion
Cinematic lighting setups
Material studies (glass, metal, diamonds, liquids)
Showcase renders where edge quality matters
ZIT prompt experimentation without CFG chaos
