Introduction to Generative AI and Large Language Models (LLMs)
The course is designed for beginners and is based on an open-source curriculum. The speaker, Carlot Cucho, is a Cloud Advocate at Microsoft specializing in AI technologies.
-
Overview of Large Language Models
LLMs represent a significant advancement in AI, achieving human-like performance in various tasks. They have the potential to revolutionize education by improving accessibility and providing personalized learning experiences.
-
Historical Context
Generative AI has roots dating back to the 1950s and 1960s, starting with simple chatbots. A major turning point occurred in the 1990s with the introduction of statistical approaches and machine learning algorithms. Advancements in hardware and neural networks in the 21st century improved natural language processing.
-
Transformer Architecture
The Transformer model, which uses an attention mechanism, allows LLMs to handle longer text sequences and focus on relevant information. Generative AI models, including LLMs, are built on this architecture.
-
Tokenization
Tokenization is crucial for LLMs, as it breaks text into manageable chunks (tokens) for processing. Tokens are mapped to indices, allowing the model to understand and generate text more efficiently.
-
Predicting Output Tokens
LLMs predict the next token based on the input sequence, incorporating randomness to simulate creative thinking. The model generates coherent and contextually relevant responses by considering the probability of token occurrence.
-
Prompts and Completions
The input to an LLM is called a "prompt," while the generated output is referred to as a "completion." Various types of Prompts can be used, including instructions, questions, and text to complete.
-
Examples of Use in Education
The speaker provided examples of how Prompts can generate educational content, such as assignments and responses to questions.
-
Future Lessons
Upcoming lessons will cover different types of Generative AI models, testing and improving performance, and comparing models for specific use cases.
