Production AI retrieval fails with semantic search alone — requires filtering, personalization, freshness, and ranking across fragmented vector DBs, rerankers, and feature stores. Tensor-native retrieval unifies multi-dimensional structures in one pass, reducing latency and ops complexity.

Vector search cracked open semantic retrieval for everyone. Embed your data, embed the query, find the nearest neighbors — it works, it scales, and it replaced a lot of brittle keyword matching. But production AI systems have evolved past the point where "similar embedding" is enough.

"Retrieval is evolving from a nearest-neighbor problem into a ranking and decision-making problem."

A GigaOm CxO Decision Brief — The Tensor Advantage in AI Search — makes the case that the gap between prototype retrieval and production retrieval is architectural, not just a matter of scale.

What actually changes in production

A real user query doesn't need just semantic relevance. It needs all of this, simultaneously:
