StabledHSTorY_SD3.5_LoRA_V1

HSTsd3ii

Model trained with AI Toolkit by Ostris <Gallery />

Trigger words

'HST style autochrome photo'

Config Parameters

Dim:16 Alpha:32 Optimizer:Ademamix8bit LR:2e-4 More info below! <br> Fine-tuned using the Google Colab Notebook* of ai-toolkit.<br> I've used A100 via Colab Pro. However, training SD3.5 may potentially work with Free Colab or lower VRAM in general:<br> Especially if one were to use:<br> ...Say, lower rank (try 4 or 8), dataset size (in terms of caching/bucketing/pre-loading impacts), 1 batch size, Adamw8bit optimizer, 512 resolution, maybe adding the /lowvram, true/ argument, and plausibly specifying alternate quantization variants. <br> Generally, VRAM expenditures for fine-tuning SD3.5 tend to be lower than for Flux during training.<br> So, try it!<br> To use on Colab, modify a Flux template Notebook from here with parameters from Ostris' example config for SD3.5 here!

Download model and use it with ComfyUI, AUTOMATIC1111, SD.Next, Invoke AI, etc.

Weights for this model are available in Safetensors format.

Download them in the Files & versions tab.

Use it with the 🧨 diffusers library

from diffusers import AutoPipelineForText2Image
import torch

pipeline = AutoPipelineForText2Image.from_pretrained('stabilityai/stable-diffusion-3.5-large', torch_dtype=torch.float16).to('cuda')
pipeline.load_lora_weights('AlekseyCalvin/HSTsd3iii', weight_name='HSTsd3ii.safetensors')
image = pipeline('HST style communist poster with text "JOIN RCA!", over autochrome color photo of Vladimir Lenin at a Dada cabaret in 1916 Zurich, dancing with red feathered drunken dinosaur, an early conceptual artist. Lenin is full of contageous awe, his blemished skin flushing with anxious excitement, his famous bald spot sweatily glistening under warm lights. In the back, Krupskaya and Inessa Armand laugh.
