Free ComfyUI Colab Pack for popular models (T4-friendly, GGUF-first, auto quant by VRAM)

Hey everyone,



I just open-sourced my Free ComfyUI Colab Pack for popular models.

Main goal: make testing and using strong models easier on Colab Free T4, without painful setup.



What is inside:

\- model-specific Colab notebooks

\- ready workflows per model

\- GGUF-first approach for lower VRAM pressure

\- auto quant selection by VRAM budget

\- HF + Civitai token prompts

\- stable Cloudflare tunnel launch logic



I spent a lot of time building and maintaining these notebooks as open source.

If this project helps you, stars, and PRs are very welcome.



If you want to support development, even $1 helps a lot and goes to GPU server costs and food.

Donate info is in the repo.

Using controlnets in 2026

Hey guys, I am pretty new to comfy(2 months) and I was wondering if anyone still use controlnets and in what ways? Specially with newer models like zit and flux, would love to know how they contribute or are they obsolete now.

Unable to create images with Illustrious XL

Hello,

I have not worked with Stable Diffusion in a long time. I returned because I wanted to use it to make some concept Pixel Art for an upcoming project. I did some research on what is currently the go to system. I ended up downloading and setting up Forge. I got the Illustrious-XL base model, but anything I enter results in abstract art. Even a simple single word like "alien" does not show anything viable.

I am sorry, if I am too noobish, but how can I investigate what fails?
