A Colossus arise.. again..

Deep under a mountain lives a sleeping giant, capable to eighter help humanity or create destruction...

This SD 1.0XL-Checkpoint is capable to produce nearly everything.. Colossus is very good creating extremly realistic pictures, anime and art.

If you like it, feel free to give me some feedback. Also if you want to support me you can do this here.

Version 12C Experimental_3

This is basically a new trained model. It uses parts of DEMONCORE Research https://tensor.art/models/750192467460212968/DEMONCORE-RESEARCH-MODEL-C2 and ArtCore. https://civarchive.com/models/556851/artcore

It also got additional training on faces, eyes, hair and landscapes.

This version works well on its own but truly shines in combination with DemonFlux. I've created a special workflow for it.

Version 10B "NeoDEMON"

This version is a pruned FP16 version from the model down below. In my tests it performed similar. So you can save 4GB of diskspace. Note that some images can be different than the full 10.6GB model.

Version 10B "NeoDEMON" (Experimental Trained)

This version is a complete rebuild based on the dataset of Version 5.3. Its based on my new not yet published DEMONCORE V4 "NeoDEMON". Parts of the graphics are from my Hephaistos 3.31. This Version is better suited for realism but also it handles drawings better.

Also it can create amazing details. I have created a special Comfy Workflow for it. Here is the link to the article. https://civarchive.com/articles/5606 The checkpoint also works well with Forge or A1111.

Please tell me your opinion about the new checkpoint.

Keep in mind V10 MidgardDEMON is very good too.. which got some benefits regarding creating lets say anthro creatures. So its also worth a look. Also check out my other versions like V9 Hera and so on :-)

Have fun creating!

Enhancer

I highly recommend to download my enhancer.. It works well with it :-) https://ko-fi.com/s/34e553e28c The main use of it is within my workflow above.

I have tested it also with Forge and it worked well with around 0.05- 0.2 but be aware that it can cause some problems with some samplers. Here is a image I have used it with Forge though.. https://civarchive.com/images/15029489

Usage and Sampler

Some advise.. Yes it can create on low steps but I recommend using about 12-16 steps with it. For the sampler.. Feel free to experiment here. I really don't recommend using Heun 2M (normal), 2M SDE (normal), 2M SDE Heun, PLMS) The other sampler should work well.

I don't use much negatives with it. This can boost the overall quality. You can use them though to "force" a style. Like if you want to create drawing... In this case you can put in "photo, realistic". Or when you want a ultra realistic image use "illustration, drawings" in the negatives. I don't recommend embeddings. You can try it but don't blame the checkpoint if it looks bad. If something appears like text or watermarks but these things in the negatives. Also you can put in NSFW in the negatives..

use CLIP skip 2 (or 3 in some cases)

The standart for this model is Clip skip 2... Feel free to try other settings though.

Here are some examples: Prompt: cinematic, a snowy mointain, a female adventurer in the foreground, dragon on mountain in the background

CLIP Skip 1 (this is not how it should be)

Clip Skip 2 (this shows the correct image)

Version 10th (X) "MidgardDEMON"

Well, I never thought to even make ten versions of this checkpoint. Here is it.. a sort of anniversary edition. Thank for all your support :-)

Finally I managed to get rid of the most of sampler bugs.. For this I had to basically rebuilt the entire checkpoint structure new from ground up.

I used a further delvelopment Hephaistos 3.31 as base and then I added parts from the latest MIDGARD model I created with Freek22 and DEMONCORE Research. https://civarchive.com/models/463847/midgard-thl-hybrid. I merged this with the 8 step SDXL Hyper from bytedance. https://huggingface.co/ByteDance/Hyper-SD

The complete visuals are crafted all over again with own trained Loras I had in my archives. This process alone took about 14 hours of worktime alone... And this was just the first step of many.. I tried to recreate everything you love about Colossus. Even with that the visuals are a bit different. Tell me if you like it :-)

So why so much effort?

The benefits are truly outstanding.. First the images are much sharper in many situations.. Second I have now a clean canvas to work with in the future.

Another benefit is the shocking cfg/scale ratio of this thing. I will add the full version in the training data folder..

For sampler: I will also add a sampler image in the training data.

The model itself works from 5 steps or less.. For the test above I used DPM++ 2S a as sampler with 16 steps.. with higher steps you can get more details some times.. Feel free to experiment with it.

There are some exeptions from the rule:

DON'T use: Heun, DPM++ 2M SDE, DPM++ 2M SDE HEUN, I also don't recommend using DPM++ 2M/Karras. Its way better than before..

For a more detailed look download the training data.

Version 9.0 "HERA"

This version is a long time in the making.. Its based on a own trained model called "Hera" which isn't public and mixed with parts of my existing version 6.0 and my Hephaistos Lightning model. It also got my SDXL Enhancer Lora and Freek22s Furry enhancer Lora mixed in. This also a sort of restart of this series. Its less censored than my last version.. This was more like a bug in the last version. Also it works with lower steps than version 6.0

Thanks to freek22 for your Furry Enhancer https://civarchive.com/models/310964/furry-enhancer-sdxl

Feel free to give me some feedback about this version.

A known bug of the model: It can't produce male organs. I know this already. Use a Lora or another model for this.

Here is some technical stuff:

I trained on more hand and feet images, so this should be better. Keep in mind that this is still SDXL and it got some limitations..

Version 9 needs less steps to start working. I recommend to start from 4 steps.. Higher steps can and will still improve the image. In my test down below I tried a range from 3-16 steps.. and 1-7cfg. As you can see: with a higher step count you can run higher or even lower cfgs.

For the working samplers go down to version 6.

Version 6.0 EXPERIMENTAL 2

Well.. its time for a new checkpoint. This one is a experimental one. Its highly coherent creative and precise. I trained on top of version 5.3 and merged Hephaistos NextGen 2.0 into the mix. This gives some advantages. It got a very high cfg/step range starting at 5 steps and even lower (depending on the used sampler of course. For the cfg range I have tested even 0.5 and it worked. For higher cfg values you have to use more steps.

The image above was made with the DPM2 a sampler. I will post a bigger version of it in the gallery.

Recommended settings

It works very well at around 2-4 cfg. As you can see above.. the recommended step count depends on the sampler and the used cfg scale.. In my test it started to work with 5 steps. for can be benificial especially for higer cfg scales.

Recommended sampler:

In my tests DPM 2 a and DPM++ 2S a worked really good for fine details. You can also use the Karras versions of these samplers.

Also DPM++ SDE, DPM++ SDE Karras, Euler a, Euler a Turbo, DDPM, DDPM Karras, DPM++ 2M Turbo, DPM++ 2M SDE Heun Exponential worked great in my tests.

feel free to test other sampler if course..

Be aware that some samplers aren't working. Don't use following samplers:

DPM++ 2M Karras, DPM++ 2M,DPM++ 2M, DPM++ 2M SDE, DPM++ 2M SDE Heun, Euler, LMS, LMS Karras, Heun, 3M SDE Karras, DPM fast, DPM2 Karras, Restart, PLMS, DDIM, Uni PC, LCM, LCM Karras

Version 5.3_Trained

This version is another nearly fully trained model. In addition it combines parts of my Hephaistos_LCM_hybrid model https://civarchive.com/models/200061/hephaistosnextgenxl-lcmbf16hybrid and Gleipnir by freek22 https://civarchive.com/models/175094/gleipnir

The result is a model capable to do very low steps while giving the possibility to gain even more details on more steps. I have added a small steps/cfg scale to the showcase. It uses DPM++ SDE from a range from 5 steps to 60 steps and a cfg range from 1 to 20 cfg. It works well with A1111/Comfy/Foocus (just turn off all styles and Loras) I highly recommend to use a -2 Clip skip with this version.

Version 4.9b Experimental_Trained

This a fully experimental model. I trained it over several weeks on base of the 1.6 Version of Colossus Project XL. Then I added parts of Version 4.9. Try it and leave a review if you like. Which version do you prefer?

Version 4.9:

This one took a long time. For this I trained even a complete new model (It will bepublic soon) I have merged in. Goal of it was to get it more stable and also added more details.

This model changes a lot.

Version 2.02 is still very good, so consider to download both and decide yourself which model you prefer...

Might discuss this even in the comments :-)

Version 2.02:

I merged in more parts from the Realistic Stock Photo Model. (about 35 percent). This increased the quality of the skin textures. Version 1.6 is still extremely good so I advise to try both versions.

Give me some feedback in form of a small review or just post some pictures in the gallery when you are pleased with the results. Also if you want to support me you can gift me a beer here :-)

Special thanks to freek22 who helped me creating this. I highly recommend his new checkpoint FenrisXL. Check out his amazing work. Also thanks PromptSharingSamaritan for letting me merge in your amazing model into Version 2.02. It really increases the skin quality a lot compared with Version 1.6.

Disclaimer and warning:

This checkpoint is fully uncensored. Only your imagination is the limit. Beware of this.. It's not intented to create just porn but it can be very horny. I would advice to consider this and maybe add NSFW in negative prompts... Don't use this to harm others... Please use this responsible! You are fully responsible for your actions!

And most important:

Don't use this to create CP! If I see such pictures here in the gallery I will flag it and you might get banned from here..

Useful tricks:

Here is the full credit list of things I used for this model including the resources I used for my other models which are merged into Colossus XL. Thanks for all your work. Please check ou their work and give them a like/review.
