Functionality built on top of large language models (LLMs) can be incredibly useful in a multitude of applications. These advanced models have been trained on vast amounts of data, enabling them to generate human-like text that can answer questions, write essays, summarize texts, and even create poetry. They can also simulate conversation, making them useful for tasks like customer service or tutoring. Additionally, they can be used to generate creative content, like stories or marketing copy, and can even help in technical fields by generating code or analyzing data.
