  • Conduct Model Testing and Grading (Bilingual): Run prompts through models and assess preliminary outputs against expectations for scientific accuracy, reasoning quality, and clarity, comparing Spanish 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 Spanish-language benchmarks before integration into official benchmarks.
