What the vendor claims, next to what independent boards measured. The two are never mixed in one column.

At a glance

Cohere's Rerank 5 targets agent retrieval costs, from $0.02 per 1M tokens

Cohere says Rerank 5 Pro ranked first on 39 of 46 composite datasets and scores 82.2 on BRIGHT. New Context Focus returns the most relevant passages in each document. Pro costs $0.05 per 1M tokens, Fast $0.02.

Why it matters: Retrieval decides which tokens your LLM pays to read; Cohere pitches passage-level reranking as a way to cut agent token bills.

Cohere releases Rerank 5 Pro and Fast with calibrated relevance scores

Cohere says Pro ranked first on 39 of 46 composite datasets. New Context Focus returns relevant passages; at a 0.4 threshold a search agent used 34% fewer tokens. API: $0.05 per 1M tokens for Pro, $0.02 for Fast.

Why it matters: Cohere says a score of 0.7 now means a 70% chance a document is useful, so one threshold can decide what reaches your LLM.
