OpenAI's ChatGPT now accessible without account, with limitations

OpenAI's ChatGPT no longer requires an account to use. Users can access it immediately without signing up. However, limitations include no chat history saving, sharing, or custom instructions without an account. Users can prevent their conversations from training the model by toggling off an option. OpenAI aims to make AI tools widely available. Safeguards are in place for users without accounts to prevent misuse.
