This means the rules governing your use of ChatGPT and other OpenAI services can change significantly, and your continued use — even without reading the update — counts as legal agreement to whatever new terms OpenAI introduces.
OpenAI's Terms of Use give the company a broad license to use content you submit — including your conversations with ChatGPT — to train and improve its AI models, which means your personal inputs could influence future AI behavior at scale. The mandatory arbitration clause and class action waiver significantly limit your ability to seek collective legal remedies if something goes wrong, a provision that may surprise many everyday users. You can opt out of having your data used for model training by going to Settings > Data Controls in your ChatGPT account and disabling 'Improve the model for everyone.'
