SegMoE-4x2-v0: Segmind Mixture of Diffusion Experts

SegMoE-4x2-v0 is an untrained Segmind Mixture of Diffusion Experts Model generated using segmoe from 4 Expert SDXL models. SegMoE is a powerful framework for dynamically combining Stable Diffusion Models into a Mixture of Experts within minutes without training. The framework allows for creation of larger models on the fly which offer larger knowledge, better adherence and better image quality.

Usage

This model can be used via the segmoe library.

Make sure to install segmoe by running

pip install segmoe

from segmoe import SegMoEPipeline

pipeline = SegMoEPipeline("segmind/SegMoE-4x2-v0", device = "cuda")

prompt = "cosmic canvas, orange city background, painting of a chubby cat"
negative_prompt = "nsfw, bad quality, worse quality"
img = pipeline(
    prompt=prompt,
    negative_prompt=negative_prompt,
    height=1024,
    width=1024,
    num_inference_steps=25,
    guidance_scale=7.5,
).images[0]
img.save("image.png")

Model Description

• Developed by: Segmind
• Developers: Yatharth Gupta and Vishnu Jaddipal.
• Model type: Diffusion-based text-to-image generative mixture of experts model
• License: Apache 2.0

Out-of-Scope Use

The SegMoE-4x2-v0 Model is not suitable for creating factual or accurate representations of people, events, or real-world information. It is not intended for tasks requiring high precision and accuracy.

Advantages

• Benefits from The Knowledge of Several Finetuned Experts
• Training Free
• Better Adaptability to Data
• Model Can be upgraded by using a better finetuned model as one of the experts.

Limitations

• Though the Model improves upon the fidelity of images as well as adherence, it does not be drastically better than any one expert without training and relies on the knowledge of the experts.
• This is not yet optimized for speed.
• The framework is not yet optimized for memory usage.
