CogVLM
CogVLM is a multimodal large language model designed for visual reasoning and multi-turn dialogue. It functions as a visual grounding model and a quantized vision model, combining text and image processing to perform complex understanding and maintain context across visual inputs.
The project includes capabilities as a GUI automation agent, allowing it to analyze application screenshots, plan operational steps, and return precise screen coordinates for interface interaction. It further supports visual grounding by generating bounding box coordinates to map text descriptions to specific spatial regions within an image.
The system covers multimodal visual reasoning, GPU memory optimization via low-precision weight quantization, and model fine-tuning using low-rank adaptation. It also provides an OpenAI-compatible interface for handling dialogue and image analysis requests.
