Pinecone Nexus: The Knowledge Engine for Agents

Introduces Pinecone Nexus, a knowledge engine for agents, which includes a context compiler for creating task-specific knowledge artifacts and a composable retriever for serving them. Introduces KnowQL, a declarative query language for agents with primitives for intent, filter, provenance, output shape, confidence, and budget. Highlights measured impacts like higher task completion rates, faster time-to-completion, and reduced token spend.
