description Overview

Vector Databases (e.g., Pinecone, Weaviate)

As LLMs become central, the need to ground their responses in proprietary, up-to-date, or specific knowledge is critical. Vector databases store and index high-dimensional embeddings (numerical representations of text/images). Proficiency here means implementing Retrieval-Augmented Generation (RAG) pipelines, allowing AI applications to search semantic meaning rather than just keywords, drasticall...

LangGraph

LangGraph is an extension of the LangChain ecosystem designed specifically for building stateful, multi-actor applications. Unlike linear chains, it allows for cycles, making it ideal for complex agents that need to loop back and correct their own mistakes. It provides fine-grained control over the execution flow, persistence for long-running tasks, and native support for human-in-the-loop interac...
