Sakana AI's Japanese-specialized model Sakana Namazu has been adopted by Iris Inc.'s Evidence Finder, a physician-facing evidence-search tool emphasizing citation transparency and hallucination control. A Namazu-based version scored 96.4% (482/500, 100% completion) on Japan's 120th national physician licensing exam (Feb 2026) — reportedly the best among GENIAC-designated domestic base models. The full algorithm (patent pending) combines Iris's retrieval approach with Sakana AI's model, cited as a sovereign-AI deployment in Japanese healthcare.
