Cohere Embed v5 Fast

Cohere

Released: September 30, 2026
Data date: October 7, 2026

Access: Cohere Embed API, Microsoft Foundry, Amazon SageMaker, or Model Vault

Cohere Embed v5 Fast shares a vector space with Embed v5 Pro, so documents indexed with Pro can be searched through the lower-latency, higher-throughput Fast variant.

Cohere positions Fast for interactive search and agent loops. It supports text, images, and mixed text-image input.

Sources and data date

Type	Evidence and data date
Research status	Research date October 7, 2026. 2 source URLs checked. This documents the inspected sources, not an exhaustive inventory of every publication.
Unresolved	full linked evaluation workbook and per-row configurations Original wording Cohere links a full-results spreadsheet, but it was inaccessible during this read. The public post omits output dimension, vector precision, sample counts, and in several tables the exact metric mapping.
Unresolved	fused and page-image metric label Original wording The chart headings call these results RCP-nDCG@10, while the nearby prose captions call them nDCG@10. Both labels are retained on each row rather than resolved by assumption.
