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 Furries but can do way more :
This model can do:
Photorealistic
Digital Art
Anime
Comic
Vector Graphics
Line art
Stickers
can write short text
etc
This is the Flux variant of Ratatoskr I fine-tuned on a merge of DemonFlux
Note: This on trained on a dataset at around 2500+ Pictures of the SDXL Version.
So the model is in some aspects still behind the sdxl model. and still in (WIP)
I recommend using the workflow with sdxl refining with the ratatoskr sdxl model
Note: the model is using an custom clip_l it's in the training and in the Ratatoskr Flux Workflow
You can test the workflow and model here:
Ratatoskr - Creature - Generator [Flux Version]
Changelog:
V1: Fine-tuned on 525 Pictures first version
V2:
so after the first " test version" with limited dataset i added another finetune with 2000 Pictures
so in total we now at 2500 pictures now so what has changed?
more consistent
some better details even without the sdxl refiner
better with lora use than V1
changed a bit the contrast level
better with nsfw
etc
to be honest this model was the most expensive i ever made so far over the time because i used external hardware again. so it will stay for now at this stage till i manage to use my own hardware.
Note: the model has a tendency for realistic and photo to correct that use the flat colors tag ;-)
V4
Model got a Huge Finetune trained at around 12K images overall, also added some own loras inside the model.
V4.10
Added an unreleased detail Lora i made into the model include a small amount of the flux hyper lora
Fixed some Color Degradation Issues caused possible by overtraining
fixed some precision issues
more stability
added some new specim and smaller details
model got a bit faster
This Model is in Early Access because ongoing tests (so this Version is still WIP)
More Details
more specim
also trained in some more art styles
better nsfw
V5.94
This model Version is Basically a new version based on V4.1 and my model Midgard Flux + new detail loras i made especially for this model.
Its unclear if this model is still a schnell model so i call it a hybrid Dev1. ;-)
the model is more precise
more details
overall more creatures
- but also a bit slower overall I can recommend this settings to start with:
Sampler: Deis
Scheduler: Beta
Steps: between 15-30 steps (25 recommended)
CFG: Between 2 and 4
There are 2 variants FP8 and GGUF (Q8)
V6.67
this model Version is basically trained from zero base model was Helheim Flux.
Updated Dataset
more detailed
for Settings:
Sampler: Deis
Scheduler: Beta
Steps: between 10- max 30 steps (16-25 recommended)
CFG: Between 2 and 4
For experimental settings:
This is a de- distilled hybrid so you can use till cfg 1.8 with a normal ksampler
recommended cfg 1.2 / 20 steps / deis / kl-optimal
V11 (Krea)
This is basically a complete new model
its based on a specific block merge between used this method: https://civarchive.com/articles/17766/guide-how-to-get-flux-krea-uncensored-and-improve-it-block-merging
Colossus_Project_KREA_Experimental,
FLUX.1-Krea-dev
and Ratatoskr (Animal, Creature and Furry) [Flux] V6.67
How the model works and technical data details visit https://huggingface.co/black-forest-labs/FLUX.1-Krea-dev
after that i trained on that base a small lora and mixed in that too to get the model more stable again and for design porpoise that it looks more again like my ratatoskr model a small dataset 305 images overall) this dataset is entirely generated on my ai model output i had with my previous models and its complete synthetic made by me without any real people or celeb images.
V11.39 (Krea)
Readjusted and modified some block weights of V11
added more parts of the V6.67 inside some other blocks
added parts of a new version of the upcoming furry enhancer for Krea
model more creative
the design is closer to the original model
way better with paws / hands
better in sfw and specially nsfw
more specim inside
added better fur and details
This model is recommended for realistic output on animals, anthro, furry and creature's
Note still in in development working currently still on some smaller details.
This model is porpoise is for realistic output on animals, anthro, furry and creature's but can also used for general usage
this model is for education and scientific purposes only not for commercial usage
i also can recommend using in some cases to improve hands the Furry Enhancer
An new workflow and a setting grid is in development.

For Online Generation (V11.39)
ERROR clip input is invalid this model does not contain valid clip.
downloaded the work flow clip but no luck.
what clip do i need to download to use this?
can you train with clip in it?
You need download the separate clips of the standard of flux t5 an clip_l and no normally you don't train with the clips in it.
@freek22 i have those, but no luck
@StreamTabulous you need to connect to both clips . The model itself runs fine
@freek22 Hi again, sorry to pester with another question but I am ignorant.
Do you still recommend I use your custom clip L file with the Krea version of Rat?
i actually see no problem in it could run fine
why does downloading the example images instead download a broken file
This is a question for civit did working fine for the last months
@freek22 i used your workflow but i cant find all the dependencies. like i cant seem to find the t5xxl_fp16.safetensors ae.sft sdxl.vae and i guess the ratatoskrV7 is a sdxl model i also dont know where to get. Where did you get these?
@khajiithasnowares this is the t5 https://huggingface.co/flux-safetensors/flux-safetensors/tree/main
The ratatoskr model is one of mine the v7 is way outdated can be found in my model list
https://civitai.com/models/192854/ratatoskr-animal-creature-and-furry
Ae.sft and vae are both common vae for sdxl and Flux
https://civitai.com/models/636193/flux-vaesft
@freek22 thank you so much my good sir.
seems to have issues making futa/dickgirl, but that might be my prompts. any suggestions, or is that just not something the model is good at? looks great otherwise!
