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
The model needs no refiner! or any other enhanced lora
This version of Ratatoskr is a merge mix Between Ratatoskr Helheim and Illustrious XL
after that i trained an realistic lora specific for this model and added it in this model Version.
Note;
the model has a tendency for realism so i can recommend using Ratatoskr Helheim for drawings.
Settings:
for settings the model needs a bit higher cfg compared to Ratatoskr Helheim from at least 3.5 to 6 is recommended steps from 15 - 40
for sampler use dpmpp_2s_a , res_5s_sde etc
scheduler / Normal , Exponential etc
Changelog:
V1.7 First Version
Description
For this update i trained an enhancer on v1.7 so this version is a "trained" version.
overall more detailed
Note: this is a heavy modified version of Illustrious so i decided for this Version update to put it in the SDXL 1.0 category , because of it's already a huge part of my mode type SDXL Helheim in it and the Enhancer that is trained on this model. the exact model type is unclear.

Did you mean to push this version as SDXL? It's very odd to see an Illustrious model become SDXL.
it is odd right but V 2.3 has a huge amount of my (sdxl hel) model type in it that is over 50% on this version so its unclear what model type this hybrid is ;-) see model description v1.7 had over 50 percent illoustrus in it.
@freek22 I also find that some Illustrious and SDXL resources can interact well, and when the generator doesn't nuke it outright, I will always try such combinations at least once. ( When it fails, it's often perfect for the Cursed Images section, though. :rofl: )
@zareltgr true i can for example recommend using the https://civitai.com/models/310964?modelVersionId=1220555
with the Illustrious model
@freek22 Yep. That's a great combo. Though for those trying R-XL 13.8, I highly do NOT recommend that LoRA with it... they seem to fight for control of too many things and often make a total catastrophe. But with R-IL 2.3, yep. Totally works.
For some reason, all Ratatoskr models have disappeared from the search results in the generator when selecting a checkpoint, and the "Create" button is missing (at least on the Red side, I haven't checked on the Green side).
still can find all my models in search
@freek22 But I can't. And there is no "Create" button on the Checkpoint/LoRA page. I can find them using the standard search (the one in the site header), but not within the Checkpoint/LoRA selection dialog.

@eXP_dot_Net well this is normal sadly civit host only a a few models for there online generator
