V2.0

So now that I've figured the model out....

  • Built in optimizer settings custom designed for your computer with recommendations

  • Removed unnecessary baggage in the image area like remove background and resize as it didn't work.

  • Fixed the issues that every other workflow had with the inferior T2I Images. It now has it's own dedicated encoder

  • Minor OCD stuff

V1.0 Beta.


I ran about 20 workflows and none of them were fast (or good) , so I spent some time figuring it out:

What's Included;

  • Options for diffusion and GGUF models

  • Optimizers (that work 🤔)

    • Model attention backend

    • Qwen image 2.1 Cache (standard)

    • EasyCache

    • I tried a few other's like Sage, Flash, and Sol, but the results were either negligable or they didn't function

  • 5 step Turbo LoRA options

  • Do Image Edit and T2I in the same workflow

  • LC vision prompt assist and enhancers

  • Multi image options

  • VOSR 2.0 Upscaler

  • Post Processing

What I found out along the way:

  • Native node for Image edit and T2I sucks. If this model picks up traction, I'll build better ones

    • There is a bleed across the image inputs that picks up latent data somehow. No clue why

    • Still figuring this model out. At one point it was giving me fish gills and deer antlers. It's kinda weird

  • Turbo LoRA gives decent results, but you really don't save a lot of time

  • Qwen 2.1 SUCKS at prompt adherence
