These habits come from the free ChatGPT lessons. ## Give it the facts - It knows the current chat, its general training and what you set up. Your current prices and policies have to come from you. - Number your facts, so you can match each claim to one. - Add the rule "Don't invent details or promise anything that isn't in the facts." - Start a new chat for a new task. ## Set the format and length - Cover Role, Context, Task and Format: who is writing, the facts, what you want back and how it should look. - Say the length, like "under 120 words", instead of trimming a 300-word reply by hand. - Ask for a table when you need one, with "Not stated" for gaps. - Ask for specific changes, like "a little warmer and under 120 words", not "make it better". ## Check every promise Copy ```text Check that reply against my facts. Make a table of every promise or claim in it and the fact that backs it up. Flag anything the facts don't support. ``` From the Reply Faster lesson. Still compare the table with your own facts. ## Words to know **Hallucination** Something false or made up, stated as fact in the same confident voice as the true parts. **Knowledge cutoff** When its training data ends. It can't know newer prices or offers unless you tell it or a tool looks them up. **Data controls** A section in Settings. Turn off **Improve the model for everyone** so a personal account's chats aren't used for training. **Temporary Chat** A one-off chat with no history or memory, not used for training. Anything you paste still goes to OpenAI. ## Keep private data out - Remove card numbers, account numbers or health details first. Only paste what the task needs. - Training off doesn't mean private: chats are still processed and stored to run the service. **Remember:** Treat every answer as a draft you are responsible for. Read the dates, prices and promises before anything goes out.
