OpenAI has announced that it is now available for free and Plus subscribers. Previously, the feature required users to allow OpenAI to use their chat history to train the AI.
Officially, users who do not wish to use the feature can still choose not to turn it on.
After turning on the history chat, the user can continue the chat from the previous terminal, which also means that ChatGPT will remember the conversation that occurred in the previous chat and will reply accordingly based on the content of the previous chat.
On the other hand, OpenAI also says that users can initiate one-time chats that won't be saved in the history.
