Introducing ChatGPT
But we also hope that by providing an accessible interface to ChatGPT, we will get valuable user feedback on issues that we are not already aware of. ChatGPT is fine-tuned from a model in the GPT‑3.5 series, which finished training in early 2022. Using these reward models, we can fine-tune the model using Proximal Policy Optimization. We randomly selected a spinalto model-written message, sampled several alternative completions, and had AI trainers rank them. To collect this data, we took conversations that AI trainers had with the chatbot. We mixed this new dialogue dataset with the InstructGPT dataset, which we transformed into a dialogue format. We are excited to introduce ChatGPT to get users’ feedback and learn about its strengths and weaknesses. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. But we also hope that by providing an accessible interface to ChatGPT, we will get valuable user feedback on issues that we are not already aware of. Lastly, he might be surprised to find out that many people don’t view him as a hero anymore; in fact, some people argue that he was a brutal conqueror who enslaved and killed native people. We’ve trained a model called ChatGPT which interacts in a conversational way. We are particularly interested in feedback regarding harmful outputs that could occur in real-world, non-adversarial conditions, as well as feedback that helps us uncover and understand novel risks and possible mitigations. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. Users are encouraged to provide feedback on problematic model outputs through the UI, as well as on false positives/negatives from the external content filter which is also part of the interface. You can choose to enter the ChatGPT Feedback Contest(opens in a new window)3 for a chance to win up to $500 in API credits.A Entries can be submitted via the feedback form that is linked in the ChatGPT interface. To create a reward model for reinforcement learning, we needed to collect comparison data, which consisted of two or more model responses ranked by quality. We trained this model using Reinforcement Learning from Human Feedback (RLHF), using the same methods as InstructGPT, but with slight differences in the data collection setup. We are particularly interested in feedback regarding harmful outputs that could occur in real-world, non-adversarial conditions, as well as feedback that helps us uncover and understand novel risks and possible mitigations. We know that many limitations remain as discussed above and we plan to make regular model updates to improve in such areas.

Today’s research release of ChatGPT is the latest step in OpenAI’s iterative deployment of increasingly safe and useful AI systems. ChatGPT and GPT‑3.5 were trained on an Azure AI supercomputing infrastructure. You can learn more about the 3.5 series here(opens in a new window).

To collect this data, we took conversations that AI trainers had with the chatbot. We gave the trainers access to model-written suggestions to help them compose their responses. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response. We’ve trained a model called ChatGPT which interacts in a conversational way. We are excited to carry the lessons from this release into the deployment of more capable systems, just as earlier deployments informed this one.
