    Version List

    UltronForever

    Most current Ultron family checkpoint version.

    Highly male centric. Fully stable natural male anatomy.

    Leaning photography, but strong with styles and artists too.

    UltronMerge

    First Ultron checkpoint. Made with TN-Triforce, MegatronMerge and RuggedResolve-BaraArt.

    Male centric. Poor male anatomy.

    Very strong styles, artists and random prompting.

    UltraNaughty

    Noise offset adjust on UltronMerge.

    Essentially a very large nighttime Lora. Deep dark image output.

    UltraMatureSaturday

    UltronMerge remerge, with addition of TN-SaturdayMorningSpecial.

    Strong 2.5D and 2D styles.

    Otherwise, very similar to UltronMerge.

    Description

    Remember how I said I wouldn't upload 50 shades of UltronMerge?..

    ...I lied.

    I really like this model. Very versatile with many art styles. The normal sized penises are a major plus. Thanks for making it!

    I can't use Side B. I get the following error in Easy Diffusion. Error: Could not load the stable-diffusion model! Reason: 'Attention' object has no attribute 'to_to_k' Here's what I found on Google... https://github.com/huggingface/diffusers/issues/4790

    @2012shawn I'm not very knowledgeable in model contents. Best I could do is clean the model up with toolkit extension:

    https://github.com/arenasys/stable-diffusion-webui-model-toolkit

    It removed some unnecessary 'keys', whatever that means.

    Try redownloading it. I replaced it with a clean one.

    @UndefinedUsername You're a genius, thank you for taking the time to fix it. It works flawlessly now. Would you mind me sharing your solution with another creator so he can fix his models? Anyway, thanks for all your work on this model. It's amazing! 😍

    @2012shawn It's an open source extension, you're free to share it with whoever you like. Just make sure that creator tests the 'clean' model in comparison to the old one. I found it can change output of some older checkpoints.

    @2012shawn As far as SideB goes - it's functionality has already been merged with UltronMerge into new version - UltronForever. It's less photorealistic than SideB, but also a lot less cooked.

    @UndefinedUsername Ah, maybe that's why I was getting over-saturated red chests. Thanks, I'll try the new version. Less realistic is always a plus for me. 👍
