How to read this provider report
Exact launch-table values from Cohere's internal multilingual evaluation suite (six of the 19 non-English languages shown). Dataset membership and per-language dataset counts are not published.
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: Arabic retrieval snapshot places Cohere Rerank 5 Pro first at 89.7. The third row is 2.3 score units behind. The broader top-10 range is 15.1 score units, so the table still separates the published systems.
7 configurations are shown for Cohere Rerank 5 launch: Arabic retrieval. 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: Arabic retrieval is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.
