The Work

You will test and improve large language models, which are AI systems that generate text. Your work will focus on Python and business analysis, helping identify where model responses are inaccurate, unclear, incomplete, or poorly reasoned.

You will create difficult prompts and test cases, review the responses they produce, and explain your findings in enough detail to guide model improvement.

  • Create complex prompts that test language-model capabilities.
  • Evaluate responses for factual accuracy, reasoning, relevance, and overall quality.
  • Find factual errors, logical inconsistencies, knowledge gaps, and other weaknesses.
  • Design edge cases that expose limitations in model behavior.
  • Provide clear, evidence-based feedback on how responses could improve.
