Nejumi.ai: Advancing Japanese LLM Evaluation with Precision and Transparency

Nejumi.ai is a cutting-edge Japanese large language model (LLM) evaluation leaderboard developed and operated by Weights & Biases, designed to assess LLMs across critical dimensions including language understanding, application ability, and alignment. Built with rigorous methodology, it uses a comprehensive taxonomy covering General Language Processing (GLP), Alignment (ALT), and domain-specific performance, ensuring robust and fair comparisons. The platform conducts both zero-shot and few-shot (2-shot) evaluations to minimize data bias, with final scores normalized on a 0–1 scale for clarity and consistency. Specialized benchmarks like JBBQ for bias, JTruthfulQA for truthfulness, and the LINE Yahoo Reliability Evaluation Dataset for toxicity provide deep insights into model reliability and ethical performance. Leveraging Weights & Biases' powerful Table and Report features, Nejumi.ai enables interactive, real-time analysis and experiment tracking, empowering researchers and developers to make data-driven decisions. With publicly available evaluation scripts, users can deploy the leaderboard privately, fostering transparency and reproducibility. Backed by GPU support from MACNICA's AI TRY NOW program, Nejumi.ai stands as a trusted, scalable resource for advancing the quality and integrity of Japanese language models.
