In Norse mythology, Ratatoskr (Old Norse, generally considered to mean "drill-tooth" or "bore-tooth") is a squirrel who runs up and down the world tree Yggdrasil to carry messages between the eagle perched atop Yggdrasil and to the roots of the tree to Nidhogg.

This model is Fine-tuned for Animals/ Creatures and Anthro and Furries but can do way more and can be used as an general use model in general use:

This model can do:

Photorealistic
Digital Art
Anime
Comic
Vector Graphics
Line art
Stickers
can write short text
etc

The model can do SFW and NSFW

This is the Qwen Image Version of my Ratatoskr Model Series

for more information about Owen Image please use the link above.

The model its trained on my own ratatoskr database and parts of the furry enhancer database . This its trained on my Ratatoskr Database and the Furry Enhancer Database so no real pictures or celeb people pictures are used for training.

for settings:

I use personal this setting:

Sampler: Euler

Scheduler: linear_quadratic/ beta57

Steps between 25 and 35

CFG from 3-4

Simple Workflows are in the images but i also will provide some in the Training folder.

i also will make some new workflows public in the future (WIP)

Changelog:

V1.0 First version

V1.8 ( Edit Model)

It's alive ........

This Qwen Edit 2509 Model version is an "Frankenstein Model" it is made by replace entire layers of the original model with Ratatoskr Qwen Image V1 ones. layer by layer so there is only a skeleton left of the original one i also have added a small lora on it too. (6800 steps on 110 paired images)

this model perform better with anthro and furry images than the original one.

Like the name suggests this model is not designed to create images only edit ones.

can do sfw and nsfw images.

do to (maybe) destroyed layers this model runs very fast at 4 steps to edit an image

i highly recommend using the workflow that i have attached to this model

the settings are:

4 steps

euler

cfg1.3

beta57 or bong_tangend

Important this provided workflow use 2 custom comfy nodes made by me that only can be found attached in the training folder

V2.99 Qwen Image

For this version i used the same Database but added some new pictures that got generated with V1 and use more pictures of the ratatoskr database in general and changed the training method slightly with V1 because its now trained on my own system even that did take some time longer to save costs but the training took about 3 weeks....

I trained on the V1 Model this time for Natural Language and e621 so it now "understand" prompts better. I also tried to get rid of the female bias a bit.

overall i added around 90k steps in training

more detailed output
better prompt following
reduced the female bias
better with nsfw stuff in general
better colors
more realistic but also keeping its drawing abilities

for settings this model version didn't changes much from V1

Sampler: Euler

Scheduler: linear_quadratic or beta

Steps between 25 and 35

CFG from 3-4

I highly recommend using the advanced workflow that is in the training foöder to get rid of the qwen grids by using z-image for upscaling.

if you like to support my work please give a thumbs up i also interested what people can do with that model i also can highly recommend using it together with the furry enhancer

V3.3

while 2.99 was the new "raw" trained model and got plenty of new things implemented (include bugs)

this versions changelog is relative short. Its more or less a bugfix of V2.99. So what did changed?

The motto was "get rid of the grid"

reduce the strength of the "Grid"
sharper images

Note that on qwen images there is always this grid so the only way to remove it completely is running the model with the refiner like before.

for settings this model version didn't change's much from V2.99

Sampler: Euler

Scheduler: linear_quadratic or beta

Steps between 25 and 35

CFG from 3-4

Workflow and examples are in the training folder.

V3.51 (Qwen Edit Image)

This version of Ratatoskr Qwen Edit is the first fully trained Version of it.

Its trained on the newest Qwen image edit 2511 mixed precision by comfy-org . This model is trained so far at 638 paired images that all got all generated by the Ratatoskr Models so its not trained on any real images or people ;-) so don't complain about that .....

Note that i also implement some split blocks of the qwen lightning lora by lightx2v

Because no one wanna a stupid slow model that needs 40 steps to function correctly ;-)

Settings of this model:

so because of the split blocks partly implemented the model has a range between

4 - 16 steps between 1cfg and 2.5 cfg

if it should stick to the image my personal setting is:

cfg1 and 7 steps

for creative edit or high quality cfg2.5 and 16 steps.

i will upload an showcase with some examples too

V4 Qwen Image (based on 2512)

This is the first Ratatoskr model based on the new Qwen Image Model V2512 so for technical details look there ;-)

This model is a Block Merged model Between My Fine-tuned Qwen Image V3.3

but its way more complex that it sounds ;-)

this Version will also used by me for further updates.

Changes:

Way more realistic
but still saved its drawing ability
i got rid of the grid now completely ;-)
a bit less horny like but this is a good thing in my opinion ;-)

V5.4 Qwen Image (2512)

trained in some parts of the colossus project database to get rid of some bias and enhance the overall realism thanks for the help https://civitai.com/user/Afroman4peace

more realistic
less biases
better general use functionality
reduced the qwen grid further

V6.95 Qwen Image (2512) (Realistic)

Let my introduce the next Model Version Qwen Image (2512) V6.95 (Realistic)

Like the model name suggest its focus is an more realistic output

this is in fact an retrain trained over a week on an rtx6000pro blackwell gpu.

the dataset of the model got extended massively. I added approx 1200 real images of real landscapes i visited and photographed myself over the years to get more realistic backgrounds as well some Animal images.

so what has changed:

Training Resolution increased from 1024x1024 to 1328x1328
specific training on text added
it now way better to difference from animals , humans and anthros sound trivial but its not ;-)
Better contrast
Realistic output
Better in difference between sfw and nsfw
the qwen grid is now almost gone
added new kinks and stuff feel free to play with it ;-)
drawings and comics still working but have an more detailed look

for settings this model version didn't change's much from V2.99 onwards

Sampler: Euler

Scheduler: linear_quadratic or beta

Steps between 25 and 35

CFG from 3-4

in general the model gets more and more creative with higher step and cfg count.

so it really depends on you what settings are better for you.

in all images is the workflow but you will find it in the training folder too with some example images.

so have fun with edit your images but keep in mind you are responsible what you do with that edit model don't blame others.

IMPORTANT:

Training such models is very time and cost intense so please help me by.

Please checking out my other models too and give like ;-) when downloading this model!

Disclaimer:

This disclaimer is not here without reasons. please have in mind this is like a virtual showroom and posting extreme stuff is like 💩 on my desk in real live 😉 and you are responsible for your own images that you generate keep that in mind.
