Qwen Image VAE Sharp and Sharp Plus is an enhanced variant of the standard Qwen Image VAE, tuned for stronger fine detail, cleaner edges, and improved micro-contrast.
Sharp (BF16/FP32) - A color-shift-free VAE that preserves the original quality while slightly improving sharpness and micro-contrast details.
Sharp Plus (BF16/FP32) – A stable, quality-focused VAE that delivers an optimal balance of sharpness, fine detail, edge clarity, and natural image quality.
Sharp Ultra (BF16/FP32) - An aggressive sharpening VAE that significantly improves fine-edge response, overall edge strength, high-frequency detail, and edge density.
The Sharp version delivers a crisper, more detailed reconstruction while maintaining the original colors, composition, and overall look. Ideal for realistic images, portraits, architecture, vehicles, sci-fi scenes, and highly textured artwork.
Enable: --fp32-vae flag for ComfyUI for FP32 VAE.

workflow inside™ so there is a proof the mistake is not on my end
you have done literally the same scammy thing like another dev did, no training, just broke it by adjusting its weights, just to farm downloads and likes.
and trying to make the commenters silent for calling this out.
+ still presenting the previous "sharp" vae as fine-tuned and good
I don't think you have to be so harsh. Those VAE are given out my @MM744 for free, so calling it a "scammy thing" just because it's not perfect yet is just unfair. Sharpening probably also makes more sense with realistic images than Anime. The VAE isn't not perfect yet, but Sharp Plus definitely goes in the right direction. I'm also testing Ultra now but I don't see any differences between Plus and Ultra yet...
curious...is it possible to train a VAE to get very fine fine art brush strokes? Like training it on close up of artwork or something to try to get the exact texture of a painter?
this is my last comment here..are you serious, guy? I just checked civarchive and saw that you swapped some files to make the new latest fake version (at least the previous attempt was more successful).
check the sha256 hashes (as of 7/25/26, day):
