🌐 What Are Foundation Models?
Foundation models are large-scale machine learning models trained on broad, diverse datasets, enabling them to perform a wide range of tasks across modalities (e.g., text, image, audio, video). These models are the backbone of generative AI and can be fine-tuned or adapted for specific business applications.
