Jina Reranker v1 Base English
Jina Reranker v1 Base English is the 137-million-parameter teacher behind the Tiny and Turbo v1 releases. Jina dates the original release to February 2024.
How the model works
The base model uses 12 transformer layers and a 768-wide hidden representation. It scores query-document interactions directly. The smaller v1 models learned from this teacher through knowledge distillation. Multilingual v2 and listwise v3 are later architectures rather than renamed versions of this checkpoint.Jina Reranker v1 Base English model details
Use and access
Jina's catalog lists managed API access. The Tiny and Turbo cards explicitly say Base was not released on Hugging Face, and a public Base weight download was not verified during review. It is therefore listed with API access only. The provider page contains conflicting context descriptions, so no single numerical context limit is asserted here.Jina Reranker v1 Base English model detailsJina Reranker v1 Tiny English model details
