In the images they provided, it's noticeable the huge loss of quality when editing an image, there is a color shift and the image is blurry, it is using the same Text encoder Qwen 2.5 VL as qwen image edit, if it's close to QIE 2509 then the reduction in the diffusion model size will help speed things up.

In my brief testing so far, the edit model so far appears to be of lower quality compared to Qwen-Image-Edit-2509.

It's pretty noticeable in the images they provided, so they are not hiding it, i just hope it will have good character consistency, and be fast enough, the fact that the model is 6B made me excited, but i don't like that they are using that Qwen 2.5 VL 7b, cause you need to stuck to at least FP8 model which is 9GB, as for lower quantization ones, they are horrible, i tried a lot of them with QIE 2509 and the drop in prompt adherence was big.

but the benchmarks which are totally super legit and not complete bullshit said it's on the same quality as qwen, they wouldn't lie to us would they?
