What the model can access
The model receives your message and the relevant April information you have enabled. Answers can be incomplete, out of date or wrong. They are not medical advice.
Temporary Chat
Temporary Chat does not use saved memory or previous chats, and it does not appear in your chat history. An encrypted copy of the response may be kept for up to 24 hours to recover interrupted delivery.
Attachments
OpenAI analyses attachments first. Your selected model receives a description of the relevant content, rather than the original file.
Safety
