AI Trainer & Model Evaluation Specialist

TextRLHF
As an AI Trainer & Model Evaluation Specialist, I contributed to the critical process of evaluating and training large language models to enhance reasoning, technical accuracy, and safety. My responsibilities included prompt creation, detailed model output evaluation, and the application of RLHF workflows to directly improve model performance. By maintaining high quality assurance and benchmarking the outputs, I ensured reliable and safe advancements in AI capabilities. • Designed and engineered complex prompts for LLM benchmarking and instruction-following tasks. • Conducted careful evaluation of model outputs, flagging hallucinations, bias, and safety issues for further training. • Applied Reinforcement Learning from Human Feedback (RLHF) principles by ranking model responses and providing nuanced fine-tuning feedback. • Maintained top-quality standards in output assessment, contributing to model alignment and reliability.
