Which is needed when you eventually build out more complex Large Language Models. 🚀 Hire me for Data Work: https://ryanandmattdatascience.com/data-freelancing/ 👨‍💻 Mentorships: https://ryanandmattdatascience.com/mentorship/ 📧 Email: [email protected] 🌐 Website & Blog: https://ryanandmattdatascience.com/ 🖥️ Discord: https://discord.com/invite/F7dxbvHUhg 📚 *Practice SQL & Python Interview Questions: https://stratascratch.com/?via=ryan 📖 *SQL and Python Courses: https://datacamp.pxf.io/XYD7Qg 🍿 WATCH NEXT OpenAI/Langchain Playlist: https://www.youtube.com/watch?v=5qP6u-WGSPk&list=PLcQVY5V2UY4Kat6vxC7ESzIIzHWdwlnak&ab_channel=RyanNolanData FAISS Vector Library: https://www.youtube.com/watch?v=ZCSsIkyCZk4&ab_channel=RyanNolanData Langchain Chains: https://www.youtube.com/watch?v=gQnJEjiaHFw&ab_channel=RyanNolanData Streamlit Langchain: https://www.youtube.com/watch?v=qXcMGBj4i3A&feature=youtu.be In this tutorial, I show you how to create OpenAI embeddings using Python and LangChain in just a few lines of code. Embeddings are the foundation of modern AI systems, converting text into vector representations that enable powerful capabilities like semantic search, clustering, recommendations, anomaly detection, and classification. I walk you through everything from basic embedding queries to more advanced document embedding workflows. You'll learn how to use different OpenAI embedding models like text-embedding-3-small and text-embedding-3-large, understand what those floating-point numbers actually mean, and see why vector databases depend on these embeddings. We start simple with single text queries, then move into document loaders and text splitters to handle larger content. I demonstrate how to chunk documents using RecursiveCharacterTextSplitter and create embeddings for each chunk, which is essential when building RAG (Retrieval Augmented Generation) systems. By the end, you'll be able to embed entire documents and prepare them for vector database storage. This beginner-friendly guide includes real code examples in Google Colab, clear explanations of each step, and practical use cases. Whether you're building a chatbot, search engine, or recommendation system, understanding embeddings is crucial for any AI application working with text data.
