OpenAI's ChatGPT3.5 now allows users to access without making an account.

Users won't be able to save their chat history without an account.

The change is starting in the US and will gradually roll out worldwide.

Some worry about data scraping abuse without account requirements.

Developers hope this change will lead to newer, better language models.

ChatGPT has over 100 million weekly users, expected to rise with anonymous access.
