Sharper details. Stronger micro-contrast. Cleaner final output.
Qwen Image VAE Sharp, Sharp Plus, and Sharp Ultra are enhanced variants of the standard Qwen Image VAE, tuned for stronger fine detail, cleaner edges, and improved micro-contrast.
All three variants are available in BF16 and FP32.
Variants
Sharp — BF16 / FP32
A color-shift-free VAE that preserves the original image quality while slightly improving sharpness and micro-contrast detail.
