Prolific Korean AI Trainer

Text
As a Korean AI Trainer at Prolific, I contributed to the evaluation and improvement of large language models (LLMs). I assessed AI-generated multilingual content in both Korean and English for accuracy and contextual relevance. I provided structured feedback and worked under governed guidelines to enhance LLM outputs. • Evaluated AI-generated text for factual accuracy and language appropriateness • Assessed tone, context, and relevancy of LLM responses • Provided critical and constructive feedback to improve model quality • Utilized a guideline-based evaluation framework for consistency
