How to read this provider report
13 datasets. Values come from the bar labels of the launch headline chart, averaged across the benchmark's datasets. RCP-nDCG@10 scores reordering of a fixed candidate set; it does not measure first-stage retrieval recall.
Cohere reports these results in its Rerank 5 launch. The linked full spreadsheet requires sign-in at capture, so this view includes only exact figures available in the public post. Model snapshots, evaluation dates, candidate-set sizes, and uncertainty intervals are undisclosed.
Each metric retains its own cohort. Rerankers reorder candidates from a first-stage search; these scores do not measure embedding or keyword retrieval on their own. These provider comparisons do not enter weighted model rankings.
The published Cohere Rerank 5 launch: nanoMTEB average snapshot places Cohere Rerank 5 Pro first at 87.3. The third row is 3.4 score units behind. The broader top-10 range is 9.4 score units, so many of the published results sit in a relatively narrow band.
7 configurations are shown for Cohere Rerank 5 launch: nanoMTEB average. The benchmark falls in the Cross-domain category. We keep external benchmark mirrors separate from the weighted global scoring system, so these results remain source-specific evidence. Cohere Rerank 5 launch: nanoMTEB average is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.
