🧩 TokenCompose SD21 Model Card

TokenCompose_SD21_A is a latent text-to-image diffusion model finetuned from the Stable-Diffusion-v2-1 checkpoint at resolution 768x768 on the VSR split of COCO image-caption pairs for 32,000 steps with a learning rate of 5e-6. The training objective involves token-level grounding terms in addition to denoising loss for enhanced multi-category instance composition and photorealism. The "_A/B" postfix indicates different finetuning runs of the model using the same above configurations.

🧨Example Usage

We strongly recommend using the 🤗Diffuser library to run our model.

import torch
from diffusers import StableDiffusionPipeline

model_id = "mlpc-lab/TokenCompose_SD21_A"
device = "cuda"

pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float32)
pipe = pipe.to(device)

prompt = "A cat and a wine glass"
image = pipe(prompt).images[0]  
    
image.save("cat_and_wine_glass.png")
