Hephaistos_NextGENXL (LCM_Bf16_hybrid)

https://civitai.com/models/200061/hephaistosnextgenxl-lcmbf16hybrid

Author's comments: This my first full LCM model. Its also the first model of the NextGenXL version of Hephaistos. Its trained on a merge of Hephaistos and Colossus Project XL with a ton of my own pictures. So because its trained on a merged model (already with own Loras inside) I call it a hybrid model. Version 2.0 is merged with Osiris Project XL https://tensor.art/models/668037070301698060

!USE DPM++ SDE/Karras or DPM++ 2Sa/Karras! It doesn't require the LCM Lora! Don't use it with this model! What is LCM? Basically LCM allows models to operate in much lower cfg and steps.. this way this model is about 6x faster than my normal checkpoints. I've tested in with A1111 and comfy.

There are sadly some downsides to it:

Some sampler aren't working anymore..

This is quite a experimental model to be honest. I still need to do more tests with it.

How to use it? Here are some settings I used for the showcase. I am working on a proper tutorial but I wanted to share this model with you early. I will add more in the future.

V2.0: I highly recommend use one of the following samplers: DPM++ SDE Karras, DPM++ SDE, DPM++ 2S a Karras, DPM++ 2S a 3-3,5+ cfg, 5-12+ steps, Clip Skip 2, use a highresfix with 0.2- 0.5 denoise and use this Upscaler https://huggingface.co/FacehugmanIII/4x_foolhardy_Remacri

Euler a: Euler a needs more steps. I used it with 15 step+ with good results.

Other Sampler are NOT working with the model. I have tested this woth A1111, a beta workflow for COMFY UI can be found here :

V1.0: I highly recommend to download version 2.0..

Working settings A1111: ( I have tested)

Euler a, 3cfg, 12 steps

Comfy: I have created some Comfy workflows but its still WIP.

This model is trained on base of a merged model (Colossus Project XL) so I will credit all creators (the stuff I used for Colossus Project XL).
