EPISODE DESCRIPTION
Jeff Huber, founder of Chroma, shares why building with large language models isn’t just about prompts or RAG—it’s about context. He explains how deciding what goes into the context window shapes reliability, why performance drops with long inputs, and how careful filtering and compaction can make AI systems faster and more useful.
