MiniGPT 4

MiniGPT-4 is a multimodal AI framework and large language model that integrates vision encoders with language models to process and reason about combined image and text inputs. It functions as a vision-language model capable of image-based conversational AI, visual question answering, and multimodal logical reasoning.

The project utilizes a pretrained vision-language integration strategy that connects a vision encoder to a language model via a linear projection layer. This approach employs frozen-backbone training to align visual representations with linguistic tokens while keeping the primary model weights static.

The framework includes a visual instruction tuning tool for specializing model weights to follow specific prompts based on visual inputs. It also provides an AI model evaluation suite consisting of assessment scripts to measure the accuracy and performance of the system across various vision and language tasks.
