What you'll learn

What makes semantic search work for code?

What's the technical difference between todays semantic search and a "standard" hybrid search + reranker from last year

What is "multi-vector" search and semantic chunking?

Learn the latest architectures and how a "single" vector per chunk is replaced with "multiple" for better search

Why wasn't multi-vector done before?

Learn the challenges of a multi-vector search and how extreme quantization with clustering is done to make it possible

Why this topic matters

Mixedbread showed in their launch how much faster/better semantic search could make Claude code. Cursor also just announced semantic embedding support, and other agents are soon to follow. I got better quality with 1/2 tokens and almost 2x faster with mixedbread search. Learn what changed from the leading researchers in the space.
