Introducing ChatGPT (2022) (openai.com)

OpenAI has announced the release of ChatGPT, a conversational AI model capable of interactive dialogue, which can handle follow-up questions, admit mistakes, and reject inappropriate requests. This model is fine-tuned from the GPT-3.5 series using advanced techniques like Reinforcement Learning from Human Feedback (RLHF), incorporating insights from previous models like InstructGPT. By employing a blend of supervised training and comparison rankings of model responses, ChatGPT aims to engage users in meaningful conversations while actively soliciting feedback to refine its capabilities. The significance of ChatGPT lies in its potential to enhance user experience in conversational AI, a field that has seen explosive growth. While the model excels in generating human-like dialogue, it still faces challenges such as providing incorrect or nonsensical answers, being sensitive to input variations, and sometimes producing excessive verbosity. OpenAI has built a Moderation API to manage harmful outputs, although it acknowledges the presence of false positives and negatives. By making ChatGPT available for free during its research preview, OpenAI aims to gather user feedback that will drive future improvements and address safety and accuracy concerns, ultimately shaping the next generation of AI systems.
