3. Intro to LLMs
Scott introduces Large Language Models (LLMs) and explains what they are and how they work. The role of these models in the AR world and the use cases for LLMs, such as writing, content creation, customer support, research, and education, are also discussed.

4. Setup Node & OpenAI API
Scott sets up the project and installs the necessary dependencies. They then explain how to set up the API key using a .env file and demonstrate how to import and use the OpenAI library. They show how to make a chat request to the AI and log the response. The instructor also discusses the concept of tokens and how they affect the cost and response of the AI. They demonstrate how to send messages to the AI and receive responses, and explain the limitations of chat models in terms of memory and non-determinism. Finally, they introduce the concept of a chatbot and explain the difference between the code they have written and a chatbot.

5. Simple AI Chat in Node.js
Scott creates a Node command-line chat interface using the OpenAI GPT-3 model. The readline module reads input from the command line, and a recursive function continuously prompts the user for input and generates responses from the AI model.

7. Search & Langchain Overview
Scott introduces semantic search, which goes beyond simple string matching to understand the meaning and context of words. Scott shares some examples of semantic search in action, such as autocomplete suggestions and recommendation systems. Langchain is introduced, and the semantic search feature in the documentation is demonstrated.

8. Embeddings & Vectors
Scott introduces word embeddings and vectors and describes how embeddings are collections of vectors that represent the meaning behind words. Embeddings are useful for storing and comparing the meanings of words and are essential for semantic search.

9. Creating a Semantic Search
Scott provides an example of how semantic search can be used to find movies with similar themes. A movie recommendation semantic search application is created, and the initial required libraries are imported. A createStore method is written to return an in-memory vector store from a list of movie documents.

10. Performing a Similarity Search
Scott codes the search function, which converts a query into an embedding and uses cosine similarity to compare it with other embeddings. The score of each search result is displayed demonstrating the proximity of each result.

11. Scaling Semantic Search
Scott discusses the challenges and considerations when deploying and scaling semantic search. Challenges include handling large volumes of data, updating and maintaining indexes and embeddings, ensuring query accuracy, optimizing for speed and accuracy, and using caching and feedback loops.

12. Document QA Systems
Scott introduces document QA (Question Answering) and compares it with semantic search. Document QA systems provide direct answers to questions, rather than just returning links like search engines. Use cases for document QA systems are discussed as well as benefits including efficiency, accuracy, and scalability.

15. Document QA Query Function
Scott implements the query function, which performs the similarity search and sends the query to the GPT model. The similarity search determines which source should be used for determining the answer. The context from the source along with the question are then sent to the model for an answer.

17. AI-Driven Function Calling
Scott explains function calling in AI models like GPT. Function calling allows the AI to call specific user-created functions to interact with the outside world and obtain up-to-date information. Significant challenges and considerations are associated with function calling, such as latency, accuracy, reliability, and security concerns.
