An LLM, or Large Language Model, is a type of artificial intelligence model designed to understand and generate human-like text. At Apple's WWDC, it was discussed in the context of on-device foundation models. These models are integrated into Apple's operating systems, such as iOS and iPadOS, and are used for various language tasks like summarization, classification, and text composition. The on-device LLMs are optimized to fit within the constraints of mobile devices, typically having around 3 billion parameters, which is smaller compared to server-based models like ChatGPT that have hundreds of billions of parameters.
