Klein 4MP Upscale Workflow
Upscales with Klein using the image both as reference and as latent.
Key Parameters
Parameter Range Effect denoise 0.6 – 0.8 Higher = more change, lower = closer to original reference/prompt 0.3 – 0.8 Lower = more reference influence, higher = more prompt influence s_noise 1.0 – 1.2 Higher = more detail added (1.2 can introduce artifacts)
Notes
reference/promptanddenoisework together — adjust both in tandemLower reference/prompt (0.3) = strong structure lock, pair with lower denoise (0.6) for tight fidelity
Higher reference/prompt (0.8) = reference has less grip, more prompt-driven, pair with higher denoise (0.8) for more creative output
