Cohere Rerank 4 Fast
Cohere
The latency-optimised variant of Cohere's Rerank 4 family, targeting low-latency and high-throughput reranking where the Pro tier's peak relevance is not required. It shares the generation's 32,000-token context window and multilingual coverage, and is billed per search query.
Strengths
- Tuned for low-latency, high-throughput reranking
- Same 32,000-token context window as the Pro tier
- Multilingual coverage across English and non-English documents
- Billed per search query rather than per token
Caveats
- Proprietary - Cohere API only
- Trades peak relevance for latency - use Rerank 4 Pro for the hardest queries
- Requires a first-stage retriever to produce the candidate set
- Cohere does not publish a release date or per-query price on its model documentation
