Omost: Revolutionary AI Image Synthesis | LLM + Gen Tech

Omost is an innovative project that harnesses the encoding capabilities of large language models (LLMs) and combines them with image generation, creating a groundbreaking image synthesis technology.

Key Features

Omost offers pre-trained LLM models based on Llama3 and Phi3 variants. These models can write code through a specific virtual “Canvas” agent to compose visual content for images, which are then generated by the actual implementation of the image generator.

Training Data

The models are trained using a mix of data, including:

• Real annotations from multiple datasets
• Extracted data from automatically annotated images
• Reinforcement from direct preference optimization (DPO)
• Fine-tuning data from OpenAI GPT4o’s multimodal capabilities

Accessibility

Omost provides an official HuggingFace space[2] as well as local deployment options, making it easy for users to start using the technology quickly.

Detailed Image Generation

Through a series of pre-trained models, Omost can generate highly detailed and dynamic images based on textual descriptions.

Applications

Omost can be used in various image generation scenarios, including but not limited to:

• Artistic creation
• Game design
• Advertising production

It helps users transform textual descriptions into visual images, thereby improving creative efficiency and innovation.

Getting Started

To start using Omost, you can either use the official HuggingFace space[2] or follow these deployment steps:

1. Clone the Omost repository:

   git clone https://github.com/lllyasviel/Omost.git

2. Navigate to the project directory:

   cd Omost

3. Create and activate a Conda environment:

   conda create -n omost python=3.10
   conda activate omost

4. Install PyTorch and torchvision:

   pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121

5. Install project dependencies:

   pip install -r requirements.txt

6. Run the Gradio application:

   python gradio_app.py

Model Variants

Omost offers three pre-trained LLM models and their quantized versions to accommodate different hardware configurations and performance requirements.
