In my last post on Stable Diffusion, I was left a bit underwhelmed with the product of my art prompts. One thing that had me questioning was why there are two  different checkpoint files on the HuggingFace repo to download? And did the smaller one just not have enough fidelity to produce great images?

We’re on a journey to advance and democratize artificial intelligence through open source and open science.

I was wondering what sd-v1-4-full-ema.ckpt means, so I once again got the Mac M1 repo and all the Python things sorted via the helpful Replicate tutorial:

Run

How

Replicate – Replicate

Instead of downloading sd-v1-4.ckpt, renaming it model.ckpt, I grabbed the 'full ema' version which was 7.72GB! Which may explain the results below as the main checkpoint is 4.28GB.

The results were a LOT better as you can see below.

They really are a better starting point for future iteration on most of them, the Porsche 911 on a beach image has me second guessing if it was just a picture taken off the internet somewhere?

Final Thoughts

I am really happy I took the time to reload Stable Diffusion and use the bigger checkpoint file as it provided drastically better results. Now, to learn the art of art prompting.
