Sakana AI announced its Japan-specialized LLM "Sakana Namazu" has been adopted by Evidence Finder, a physician-facing evidence search tool from Tokyo-based medical AI company iris. The tool searches databases like PubMed and generates answers with cited sources, including a Verify feature that checks cited references actually exist; Namazu handles literature comparison, synthesis, and answer generation.
- Benchmark: An evaluation model built on Namazu scored 96.4% on the 120th Japanese national medical licensing exam (Feb 2026) — reportedly the highest publicly known score among METI GENIAC-designated domestic foundation models.
- Approach: Sakana's post-training avoids catastrophic forgetting, preserving base-model math, knowledge, and coding benchmarks while improving Japanese instruction-following, translation, and Japan-specific context.
- Plans: Sakana says it aims to make strong open models usable in Japan and to build domestic inference infrastructure for Japanese enterprises.
