OpenAI has unveiled CriticGPT, an AI model specifically designed to identify and correct errors in code generated by GPT-4. This new model leverages reinforcement learning from human feedback (RLHF) to enhance code quality, achieving a 63% improvement over ChatGPT in error detection. While still under development, CriticGPT has the potential to revolutionize code review and enhance the reliability of AI-generated code.
