Textbook mechanism diagram for Cohere Embed 5 retrieval architecture: text and image inputs entering two differentiated Pro/Fast embedding paths that converge into one shared vector space; depict a long-context intake ribbon, multilingual streams, Matryoshka nested vector dimensions, and downstream retrieval neighborhoods without inventing benchmark scores.

Summary: Cohere introduced Embed 5 Pro and Fast as multimodal enterprise embedding models that share one vector space while supporting long-context, multilingual and Matryoshka-style retrieval workflows.

Why it matters: A shared embedding space lets teams trade quality and speed without maintaining separate retrieval indexes, making model choice an operational control rather than a data-migration event.
