Beyond Images
Fused Embeddings in Production

One index, every modality
The production payoff of alignment: a single embedding index holding images, text, audio — queried by any of them. 'Search our catalog with a sentence', 'find songs that feel like this clip', 'match this screenshot to its doc' — same infrastructure, one nearest-neighbor lookup.
The economics are why this won: embed each item once at ingest, serve queries at millisecond latency, swap modalities without re-architecting. Joint embeddings turned 'cross-modal search' from a research project into a commodity feature.
insight
A shared embedding space is a universal translator that runs at index-build time. Everything after — the ANN lookup, the ranking — is infrastructure you already own.
