Model comparison
Compare Cohere Rerank 4 Pro and Jina Reranker v3.5 using the same provider-sourced reranking & retrieval rubric. No mystery score and no invented benchmark ranking.
Facts checked September 4, 2026
Quick take
Cohere's quality-first reranker for improving search and RAG results across multilingual text and semi-structured JSON.
One billing unit includes up to 100 documents, not the endpoint's full 10,000-document request limit. Long documents can become several billable chunks.
Jina's compact listwise reranker for long, multilingual, structured, legal, financial, and domain-specific candidate sets.
The open-weight license is non-commercial, not Apache or MIT. Provider latency figures use specific A100 test setups and should not be treated as your production SLA.

How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
Cohere enterprise customers can opt out of training; SaaS prompts and generations are generally deleted after 30 days. Approved zero-data-retention accounts and private or third-party deployments offer stronger controls.
Provider and API links
Self-hosted and air-gapped deployments keep request data inside infrastructure you control. The reviewed hosted API pages do not state a complete retention or training-use commitment, so confirm Jina or Elastic terms for sensitive search data.
