AI models are the backbone of artificial intelligence applications, enabling machines to learn from data, recognize patterns, and make intelligent decisions. Popular AI models include neural networks, decision trees, support vector machines, and generative AI models like GPT and GANs. These models power applications in various industries, from self-driving cars and AI chatbots to fraud detection and medical diagnosis. Deep learning models, such as convolutional neural networks (CNNs), are widely used in image and speech recognition. AI models continuously evolve, improving automation, predictive analytics, and personalization. Businesses leveraging AI models gain operational efficiency, data-driven insights, and enhanced customer engagement, making AI an essential tool for innovation in the digital economy.
