As an AI Evaluator and Model Response Reviewer, I assessed AI-generated text outputs for factual accuracy, relevance, and clarity. I used rubric-based criteria to rate and provide feedback on model responses, ensuring quality and detecting hallucinations or inconsistencies. My tasks involved giving structured feedback to enhance model performance in remote contract environments. • Applied consistent guidelines for response quality evaluation across diverse subject domains. • Identified errors such as contradictions and hallucinations in AI outputs. • Wrote actionable, detailed feedback on model performance and response limitations. • Utilized strong analytical reasoning and data judgment in remote asynchronous settings.
