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
Model got a Huge Finetune trained at around 12K images overall, also added some own loras inside the model.
More Details
more specim
also trained in some more art styles
better nsfw
for Settings i recommend using euler, ddim, or dpmpp_2s_ancestral , between 8-15 steps, simple , normal or beta scheduler. cfg is at 3.5 or less.

v2.9 gives me fantastic results, both in text and image quality. Great work!
I paid the buzz to access v3.9 and honestly I'm a little disappointed in it. Both the image and text quality seem to be inferior to v2.9 IMO. I was hoping that it would be better with furry hands, something 2.9 struggles with, but both were equally struggling in that regard.
sorry to hear that in theory the model is working better at least it was in my internal testing . will look into that issue, maybe it's the workflow the model is only tested so far without enhancer workflow.
@freek22 Thank you for the reply. I don't mean to discourage you. I am a big fan of your models. Ratatoskr for XL is probably my all-time favorite XL model. I will be looking forward to your next releases.
@Foxbite hi i found an small issue in the current version and fixed it but you need to download the version again
@freek22 Hey thanks. I got it, but sadly I feel like i'm still getting the same kind of results. Should I change anything in my workflow? I'm still using the same clips and settings I used for v2.9. I will say the hands do seem to be more furry, but the quality just seems kind of rough, like my cfg is too low or something. I'm using 3.5 guidance.
@Foxbite yes there some changes in the workflow will update it today for example it seems the model needs sometimes more steps (15)
@Foxbite aslo changing the cfg down to 2 can help also using ddim/beta at 20 steps with the old workflow or dpmpp_s_ancestral with 15 steps/ simple
@freek22 I used your posted workflow for v4 and I'm getting WAY better results! I think my problem all boiled down to bad settings. Thank you so much for your help on this!!!
@Foxbite good to hear ... it seems the massive training has changed a lot on this model include the settings
4.0 is very nice! It definitely needs a lot of work on the tail positions though. Especially if we see the back of an anthro animal. The tails most of the time are too short, are floating, very malformed and unrealistic, or are in questionable places (like INSIDE the ass... its not supposed to be a buttplug...)
Iam just working on that issue , I train right now the next furry enhancer lora that will get rid of these problem
@freek22 Awesome. Also is there anyway i can use your suggested workflow for other SDXL models? I really love the upscalers
@awesomejoshjack977 sure works with nearly any sdxl model, you may need to change the denoice, cfg or sampler depending on the used model
improved the tail situation with the new update
@freek22 I still dont see any improvement with the tails but i could be doing something wrong. I used one of the workflows you made on this version with the snow leopard and tried other animals and it still seems to be confused with the tails. could be an issue with flux in general
@awesomejoshjack977 it seems so also in the base version there a no anthro characters at all so this is basically made from scratch
v4.0 unlike the latest SDXL v7.3 version, rarely generates full-length characters with full body image capture. Portrait photos are more common than compositions with the entire character. What is the reason, are there any special features of prompting for this model?
SDXL is completely different model base than what this uses. You should include everything you want in the prompt, such as "full body".
Yes full body helps also describe the scene and background details helps , this is indeed a completely new model even its trained on the same database.
