Jev-Style Reranker Decision Engine

Han Xiao put a Jev-style API on jina-reranker-v3.5 as a decision engine that always pulls the lever in the trolley problem, whether one person or one billion would die.

I put a Jev-style API on top of jina-reranker-v3.5 to turn it into a "System 1"-like decision engine, and it always pulls the lever in the trolley problem, whether one person dies or one billion 💀 jina-reranker-v3.5 was trained to maximize retrieval relevance, not the rationality of a decision. But at least the I/O part works: a listwise reranker can be dropped in as a "decision maker".

The reranker was trained to maximize retrieval relevance, not decision rationality. Xiao said the I/O works and that a listwise reranker can be used as a decision maker.
