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.

Description
so after the first " test version" with limited dataset i added another finetune with 2000 Pictures
so in total we now at 2500 pictures so what had 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
a tiny bit better in ram usage
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.

'UnboundLocalError: cannot access local variable 'dtype_t5' where it is not associated with a value'
I am using the supplied 'google_t5-v1_1-xxl_encoderonly-fp16.safetensors' from Comfy Manager. It works with Dev and gguf no problemo. Just not your checkpoint. Not even if I load your workflow (installed missing SD3 node once loaded and switched T5xxl_fp16.safetensors to the Google one). I assume they are the same?
Nothing to do with T5. It works if I move your checkpoint into the unet/flux1 folder and load it with the Comfy diffuser loader. I am not sure why your checkpoint does not work with it in the checkpoint folder with your workflows loader.
I have the model in my checkpoint folder no problem so far really strange did work on many systems I tested. This message is there when there is a problem with t5 normally will test these 1_1 t5 used before 1.0 and it's also an decoder only version it seems... Ratatoskr is not an dev1 model. More like an flux1 schnell hybrid
awesome model. any plans for gguf version?
there are plans but it seems the model don't like any convert attempt failed so far.
@freek22 I got the same question on one of my models, how you convert them anyway?
@JayNL I will write you back when I figured out it's planned with the v3 version I released today
any special trigger for avoiding nipples and pussy visible trough clothes? on almost al images the pussy and nipples are exposed and are visible through the clothes. the 2.9 version did not have that problem.
@elguachiiii the best is more avoid words it seems like medium breast. Flux is hard to train in first place. In my tests I had not seen that problem very often .... I am Working on an enhancer for the model that could help in theory but will take another few days till finished.
Hi, I'm completely new to Stable Diffusion, may I ask how I get this to work, what do I need to install? tried it directly in models but didn't work. Thank you
there are 3 ways: with comfy download or update to ne newest version install the comfy manager and put in the workflow data 2. download forge or use online generation https://tensor.art/template/760455605344327915 keep in mind that for the model you need a lot of vram at least 12gbvram
I manage with 8Gb, although max resolution bit limited. Usually it won't be enough for full 2560 by 1440p, 1080 it can do just fine though, and custom resolutions in between.
