Prolific is a platform that provides real human data and can help large AI model manufacturers conduct RLHF (Reinforcement Learning from Human Feedback) training. RLHF combines human guidance with automatic reinforcement learning to optimize the decision-making ability and output content of AI through human evaluation and guidance. Prolific has established a community of over 120,000 people and provides high-quality data for over 3,000 well-known organizations. They ensure the authenticity of the provided data by authenticating participants and filtering data collection tasks. Prolific believes that high-quality training data is very important for large AI models, which can reduce hallucinations and illegal outputs, enhance RLHF capabilities, and avoid data disputes. Through RLHF, AI can quickly improve its content output ability under human supervision. Prolific's data can be used for various tasks. For example, translation models can obtain suggestions from professional translators to make the translated content more natural and closer to reality.
