Today we release jina-reranker-v3.5, a 0.6B-parameter listwise reranker that keeps the last but not late interaction of jina-reranker-v3 and makes it faster and far more capable on the data enterprises actually search. It reaches 63.20 nDCG@10 on BEIR, ahead of Qwen3-Reranker-4B with roughly 7× fewer parameters, and it reranks up to 1.56× faster than v3 on long documents.

A security flaw in widely used crime lab equipment exposed digital DNA evidence to undetectable tampering.

Using Antrophic’s Claude to exploit a security flaw that’s existed for decades, researchers successfully added and removed DNA profiles from files, meaning bad actors could theoretically frame an innocent person or erase a suspect.
