VibeRL is an AI agent designed to simplify the fine-tuning process of Reinforcement Learning (RL) by automating complex setups, allowing users to merely provide a dataset and a prompt. This innovation eliminates the need for intricate manual adjustments, making RL more accessible. Preliminary tests demonstrate VibeRL's efficacy in diverse tasks such as grade school math and coding challenges, with notable improvements in accuracy. For example, in solving math problems, accuracy increased from 52% to 85%, and for LeetCode challenges, it rose from 34% to 63%. VibeRL's automation of RL workflows holds promise for making model customization easier, with plans to develop it into a product that requires less engineering and more intuitive interaction, enabling users to leverage data effectively without deep technical expertise.
