LLMs & Generative AI

Production-grade LLM applications with prompt engineering, RAG systems, and modern AI development patterns.

Quick Start

# Production RAG System with LangChain (2024-2025)
from langchain_openai import ChatOpenAI, OpenAIEmbeddings
from langchain_community.vectorstores import Chroma
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain_core.prompts import ChatPromptTemplate
from langchain_core.runnables import RunnablePassthrough
from langchain_core.output_parsers import StrOutputParser

# Initialize components
llm = ChatOpenAI(model="gpt-4-turbo-preview", temperature=0)
embeddings = OpenAIEmbeddings(model="text-embedding-3-small")
