Vision Language Models (VLMs) merge visual and language skills, enabling them to explain images with a human-like touch.VLMs excel in tasks like image description, video comprehension, question answering, and image generation from text.Their functioning involves a vision system analyzing images and a language system processing text, trained on vast image-text datasets.Chain-of-Thought reasoning in VLMs ensures step-by-step explanations, enhancing transparency and trustworthiness of AI decisions.CoT facilitates tackling complex problems, as seen in healthcare diagnostics and self-driving car decision-making.In industries like healthcare, self-driving cars, geospatial analysis, robotics, and education, VLMs with CoT are revolutionizing processes.In medicine, VLMs like Med-PaLM 2 diagnose based on symptoms, providing detailed reasoning for doctors to follow.Self-driving cars leverage CoT-enhanced VLMs for safer navigation and natural language explanations of actions taken.Google's Gemini model integrates CoT to expedite geospatial analysis for disaster response and decision-making.In robotics, CoT and VLM integration enhances planning and execution of multi-step tasks, boosting adaptability and response clarity.
