Questions This Video Answers
What are Large Language Models (LLMs) and how do they work?
LLMs are AI models trained on vast amounts of text data to predict the next word in a sequence. They consist of parameters and code, requiring significant computational resources for training.
What is the difference between pre-training and fine-tuning?
Pre-training involves training the model on a large, general dataset, while fine-tuning adapts the model to a specific task or domain using a smaller, more focused dataset.
What are some of the security risks associated with LLMs?
LLMs are vulnerable to attacks like jailbreaking, prompt injection, and data poisoning, which can compromise their intended behavior and security.
How can LLMs be improved in the future?
Future improvements include self-improvement through reward functions, customization for specific tasks, and the integration of tool use and multimodality to enhance their capabilities.
