Golden Finance reported that OpenAI’s 12 consecutive working days of presentations have entered the second day, and today’s introduction is the Reinforcement Fine-Tuning Research Program. It is reported that the project aims to enable developers and machine learning engineers to create fine-tuned expert models. New model customization technology enables developers to customize models with tens to thousands of high-quality tasks and grade the model's response based on provided reference answers. This technique enhances the model's derivation of solutions to similar problems, as well as its accuracy on specific tasks. OpenAI said it encourages research institutions, universities and businesses to apply for use, and expects positive results in fields such as law, insurance, healthcare, finance and engineering, because the model has an objectively "correct" answer (which most experts would agree on). Excellent performance in tasks.
