description Overview

Haystack

Haystack is a modular framework for building production-ready search and QA systems. It focuses on creating pipelines where components (retrievers, rankers, generators) can be swapped out easily. Its architecture is highly structured, making it an excellent choice for enterprise environments where predictability and maintainability are paramount. Haystack provides deep support for various retrieva...

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...
