Tips

Use DPM++ SDE sampler for best results at higher CFG and steps.

For creatures, it is highly recommended to use the Furry Enhancer model.

FenrisXL VAE is recommended for the V7.0 and later versions.

Creative artwork versions are available, but NewdawnXL or V8.09 are recommended for art styles.

For the Flux variants, recommended settings include 10 steps, 3.5 CFG with euler/simple or ddim/beta samplers.

CFG ranges vary widely from 1 to 30+, adjust according to desired output detail and creativity.

For SDXL Lightning version, recommended samplers include euler, euler_a, dpm_2_ancestral, dpm_adaptive, dpmpp_sde or gpu versions, ddim, and uni_pc_bh2.

Sampler/CFG grid testing is planned to further optimize use.

Use at your own risk; responsibly control creation content.

Version Highlights

This is the First SDXL Lightning Version of Fenris XL and still experimental: (V1.5)

if you need infos what SDXL Lightning is: you can read here about it:

  • very fast model

  • very detailed

  • better in art styles

  • no lora needed for sdxl [Lightning]

for settings i recommend the following settings:

dpm++ sde/ sgm uniform scheduler ...between 4-15 steps and and around 2-max 4 CFG

(i use for myself most of the time 7 steps )

( see example images and xyz grid)

Note; not every sampler are working: Here a list of working ones:

euler, euler_a, dpm_2_ancestral, dpm_adaptive, dpmpp_sde, dpmpp_sde_gpu,
ddim,uni_pc_bh2, for more infos see settings its contains a huge xyz grid

for a workflow you can use the Mjölnir Workflow or the FenrisXL workflow by afroman4peace

I can highly recommend using the Furry enhancer for creatures ;-)

this model version use parts of following models , Hephaistos Next Gen thanks for your help Afroman4peace, parts of Ratatoskr and of course parts of the original SDXL Lightning Model

please check out also there amazing work !

Fenris ( Fenrisúlfr) , Fenrir or also old norse "Vánagandr" , the First son of Loki it is foretold that he will kill Odin in Ragnarok.....

This model was actually made for animals and creatures but with the further progress of the model it's also good as an general model for all sorts of generations.

    Please Check them also out

    Note:

    The best results I got from CFG 1 to 6 at 40 to 80 steps

    7-11 CFG 70 to 200 steps (for example 10CFG /100-150 steps)

  • or at 12-16 CFG (200-300 at 12) / 400 - 600 steps at 16 CFG

    (DPM++ SDE)

    V7.0 / V7.03

  • refined V5.5 also merged with models (6.xx) that never get released

    merged in XL13 Asmodeus

    I decided to split the model thats the reason for two V7.0 Versions

    V7.0

for creative artwork, anime , comic, drawings, and digital art

7.03

if you need more realistic outcomes.

Note: for 7.0/7.03 i recommend using the "FenrisXL VAE

for the next Versions i will bake this VAE in from the start!

V8.01

  • added more training

  • merged in small amounts of XL6 - HEPHAISTOS V 3.3

  • trained in small amounts of ashrpg loras

  • more realistic, consistent and creative than V7.03

  • it can handle a huge range of CFG from 1-30+

  • Please Check out their amazing work

V8.09

  • Merge between V8.01 and V7.00, V7.02 ,V5.01. , NewdawnV2.2

  • I also added a bit train difference from Yamers Perfect Design

    Model

  • Made for creative stuff (Digital Art, anime, and drawings)

i recommend using V9.22 for photorealistic Images.

V9.22

  • Merged in some small parts of the Thalos Project,

    XL6 3.31

  • Some parts of Fenrisxl 8.09

    and lots of new Training Data!

    • better overall quality

    Version got deleted because it had a bug that let the model overbake sometimes and ruined the image sorry about that

    V10.03

Fixed V9.22

Recommended for Photorealism

V11.12 (Creative Photo)

  • Brings the design back from V8.01 (i also merged in back i huge amount of it back in)

  • added back the posibility for creative stuff did archieved that because i merged in a small amount of newdawnXL

  • merged also in Colossus Project XL v1.0

  • i also switched the merging method a bit thanks to Triple_Headed_Monkey

    there will be no creative artwork Version anymore because i still recommend using NewdawnXL or V8.09 for that

V12.8 (Photorealistic)

  • This Model is the upgrade of V10.03

    • More photorealistic

    • more training overall

    I recomment for Creative Photos V11.12

V14.5 Experimental Version

this is basically Newdawnxl with an fenrisxl picture output

  • more linguistic and intuitive

  • more creative

  • can go from low resolutions from 256x256 (512x512 recommended) to 1200x1200 but can go over this limit too but no guarantee for consistency anymore

  • it can do artworks again but i still recommend newdawnxl for that

There is also an tensor.art only version with an slightly alternative output and some small technical improvements over 14.50 I recommend this version to use online when you have an potato computer or you like generating images on the go

https://tensor.art/models/645967964966858122

V15.8

It been a while since the last update because it was pretty hard to improve FenrisXL

Merged in Gleipnir

and add lots of Extra Training:

  • Visual improvements

  • More versatile and an increased creativity include artworks and drawings but i recommend also looking into Newdawnxl

V16.4

I used some parts of my Bifröst Project model to update this Model this time

  • more Photorealistic

  • more consistent

  • more flexible

Even the results are good I'm always working on the model to make it even better in some way expect lots of updates, experimental stuff ,I'm very creative and have lots of ideas and like trying to break technical limits. That's the reason I'm never done with this model.

FenrisXL [SDXL Lightning]

V1.5 First released Version

euler, euler_a, dpm_2_ancestral, dpm_adaptive, dpmpp_sde, dpmpp_sde_gpu,
ddim,uni_pc_bh2, for more infos i made an xyz grid i will upload it soon.

for creatures i can highly recommend to use the Furry Enhancer

for a workflow you can use the Fenrisxl Workflow made by Afroman4peace

this model version use parts of following models , Hephaistos Next Gen thanks for your help Afroman4peace, parts of Ratatoskr and of course parts of the original SDXL Lightning Model

V18

  • more precision

  • more styles

  • without changing the classic fenrisxl style

    Added elements of my model RatatoskrV7 and Ragnarök inside the model.

    for Release FP32 / Bf16 is available, the FP16 version will follow later.

    for the workflow you can check out

    i recommend for the workflow to use for example the ragnarök workflow

but i will do a full sampler / cfg grid soon on this model soon too.

please check out also out the newer models like Ragnarök for example.

Fenris Flux V1

First Version of the Flux Variant of Fenris this model is based on Ratatoskr Flux (V1)

This model has an Style Lora inside trained on 1200 output Pictures generated by Fenrisxl

(15,8-V18) i recommend the following workflow

I can recommend for settings: 10 steps 3.5 cfg and euler/simple or ddim/ beta

Fenris Flux V2.3

Finally after Month in training i am Done With the new Version of Fenris Flux.

This Version is trained on a mix of Fenris V1 / Helheim Flux Base Model so its an hybrid model.

it also contains an custom trained Clip_L made for this model so i strongly recommend using it in comfy instead of a separate dual clip ( see my workflows embedded in all Gallery pictures)

  • more realistic

  • but can still do art

  • trained on extended database compared to V1

    recommended settings to start with: 16 Steps / Sampler Deis / Scheduler beta

Have fun with the new Model and please give a thumbs up to support my work

Note i will also release the fp16 and the gguf variant stay tuned

please give some feedback if you like ;-) to improve it even further

and if you like buy my buddy a beer that we will then drink together

!!!Use it at your own risk, you a responsible for your own creations!!!

important: for the Flux variant: I got asked if there are parts of dev1 in it the answer is yes a tiny amount if you consider it for commercial use do it on your own risk!

PS: will report every sick photo that is posted here! (CP, brutal Gore, etc)

This disclaimer is not here without reasons. please have in mind this is like a virtual showroom and posting extreme stuff is like 💩 on my desk in real live 😉
