ChatGPT is free to use, though we do have subscription plans available, available on our pricing page.

ChatGPT is fine-tuned from GPT-3.5, a language model trained to produce text. ChatGPT was optimized for dialogue by using Reinforcement Learning with Human Feedback (RLHF) – a method that uses human demonstrations and preference comparisons to guide the model toward desired behavior.

These models were trained on vast amounts of data from the internet written by humans, including conversations, so the responses it provides may sound human-like. It is important to keep in mind that this is a direct result of the system's design (i.e. maximizing the similarity between outputs and the dataset the models were trained on) and that such outputs may be inaccurate, untruthful, and otherwise misleading at times.

ChatGPT is not connected to the internet, and it can occasionally produce incorrect answers. It has limited knowledge of world and events after 2021 and may also occasionally produce harmful instructions or biased content.

We'd recommend checking whether responses from the model are accurate or not. If you find an answer is incorrect, please provide that feedback by using the "Thumbs Down" button.

As part of our commitment to safe and responsible AI, we review conversations to improve our systems and to ensure the content complies with our policies and safety requirements.

When you use our services for individuals such as ChatGPT, we may use your content to train our models. You can opt out of training through our privacy portal by clicking on “do not train on my content,” or to turn off training for your ChatGPT conversations, follow the instructions in our Data Controls FAQ. Once you opt out, new conversations will not be used to train our models.

We don’t use content from our business offerings such as ChatGPT Team or ChatGPT Enterprise to train our models. Please see our Enterprise Privacy page for information on how we handle business data.
