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.

WAN 2.1:

This WAN 2.1 Model is trained based on parts of the Ratatoskr Helheim / Flux Database

its made to animate Ratatoskr image outputs

so the model is better with animate , Animals , Anthro , Furry and Fantasy Creatures than the standard model.

the model can do SFW and NSFW

the model can handle different resolutions between 480p and 720p (even slightly above)

WAN V1.0:

I also recommend using any Ratatoskr based Pictures to generate Videos with it.

WAN 2.2 Hybrid V1.0:

This is an Hybrid model between parts a customized Wan 2.2 (WAN2.2-14B-Rapid-AllInOne T2V V1) and the V1 Version of Ratatoskr WAN 2.1

It's made with specific block merging and for now an wip model i will sure try also train in the future.

Like in the original WAN2.2-14B-Rapid-AllInOne Model the refiner is merged inside the model

so you can generate the image in with one ksampler but it needs 6 Steps instead of the 4 steps of the original Wan 2.2 Custom model and other Settings:

6 -10 Steps

Sampler Recommended: Uni PC BH2

Scheduler: Beta or sgm_uniform

cfg between 1 and 1.2 is tested

• Overall this model is better with anthro and furry creatures than original also better in the nsfw area than standard WAN 2.2

Note: if you like T2V i made a Lora for that you can download and test it here: https://tensor.art/models/872785610920689931/Ratatoskr-WAN-Alpha-T2V-WIP-V0.4-WIP

There is also an Lora that i have build before i trained the model. i recommend to check it out.

the Model is trained at around 2700 pictures and 230 Videos.
