As an AI Model Trainer at Mercor, I created and refined high-quality, human-aligned content to train frontier AI models. I developed base prompts on generalist topics and evaluated AI-generated responses for clarity and accuracy. My work included prompt–response iterations with varied lengths, styles, and system prompts. • Applied consistent quality standards to summaries and question-answering tasks. • Identified gaps or failure points in AI responses for benchmarking. • Supported a leading AI research partner in data training tasks. • Worked with text data within content creation software.
