GPT-4 Vision is a multimodal model that integrates computer vision and language understanding to process text and visual inputs. It excels in tasks like Optical Character Recognition (OCR), Visual Question Answering (VQA), and Object Detection, but its limitations and closed-source nature have spurred interest in open-source alternatives. These alternatives offer flexibility and adaptability, making them pivotal for a diverse technological ecosystem. They allow for broader application and customization, especially in fields requiring specific functionalities like OCR, VQA, and Object Detection. Open-source models like Qwen-VL, CogVLM, LLaVA, and BakLLaVA have been developed to address these needs, each with their strengths and weaknesses. The choice of model depends on the specific requirements of the task, such as language support, text extraction accuracy, and image analysis detail. These open-source large multimodal models process diverse data types, enhancing AI accuracy and comprehension, and promise a more human-like understanding of complex queries.
