No puedo mejorar la calidad de la imagen

Hello @CharoTir,

Thank you for your message. 

Did you use model 3 or model 4?  Model 4 does not have fast mode, so those images cannot be upscaled.

If you can upload a screen shot of the full browser window on the generation page, we can look at where you are and tell you for sure what is happening.

Thanks,
