Model Description

A major challenge of using generative artificial intelligence has been the problem of size and speed. Handling text-based language models easily becomes a challenge of loading entire model weights and inference time, it becomes harder for images using stable diffusion. SSD-1B is a distilled 50% smaller version of SDXL with a 60% speedup while maintaining high-quality text-to-image generation capabilities. It is trained on diverse datasets including Grit and Midjourney scrape data, and excels at creating visual content based on words. This was achieved by the strategic distillation of knowledge from expert models (SDXL, ZavyChromaXL, and JuggernautXL). This distillation process, coupled with training on rich datasets, equips SSD-1B to handle a spectrum of commands.

Model Architecture and Training Details

SSD-1B is a 1.3 billion parameter model that distinguishes itself by removing several layers from the SDXL model, optimizing its architecture for efficient text-to-image generation. Key hyperparameters used for training include 251,000 steps, a learning rate of 1e-5, a batch size of 32, an image resolution of 1024, and the implementation of mixed precision with fp16. The model’s adaptability shines as it supports different output resolutions, ranging from 1024×1024 to more unconventional sizes like 1152×896 and 896×1152.

In a notable speed comparison, SSD-1B achieves speeds up to 60% faster than the foundational SDXL model, a performance benchmark observed on A100 80GB and RTX 4090 GPUs. This architectural finesse and optimized training parameters position SSD-1B as a cutting-edge model in text-to-image generation.

Python Code Demo with Segmind SD-1B

To use the SSD-1B model, you can follow these steps. First, make sure to install the necessary libraries. you can find the entire notebook here: https://github.com/inuwamobarak/segmindSD-1B

1: Install Diffusers

# Install diffusers from source:
!pip install git+https://github.com/huggingface/diffusers

# Additionally, install transformers, safetensors, and accelerate:
!pip install transformers accelerate safetensors

2: Import the necessary modules and initialize the model

from diffusers import StableDiffusionXLPipeline
import torch

# Initialize the pipeline using the pre-trained SSD-1B model:
pipe = StableDiffusionXLPipeline.from_pretrained("segmind/SSD-1B", torch_dtype=torch.float16, use_safetensors=True, variant="fp16")

# Set the device to use (set to "cuda" for GPU acceleration):
pipe.to("cuda")

3: Define your prompts

# You can change these to generate different images:
prompt = "An astronaut riding a green horse"
neg_prompt = "ugly, blurry, poor quality"

4: Generate an image based on the provided prompts

image = pipe(prompt=prompt, negative_prompt=neg_prompt).images[0]

# You can now use the 'image' variable to work with the generated image.

5: View Image
