• Conduct Model Testing and Grading (Bilingual): Run prompts through models and assess preliminary outputs against expectations for scientific accuracy, reasoning quality, and clarity, comparing Japanese vs. English where needed.

• Support Benchmarking and Quality Assurance: Collaborate in QA review processes to ensure prompt tasks and rubrics meet scientific rigor, maintaining consistency and reliability across Japanese-language benchmarks before integration into official benchmarks.
