Module 2 · Prompting — getting a real answer Lesson 4 of 15
How Grok reads what you type
Context, instructions and roles. Grok answers from its training data unless live access is on, and it will not always say which it used. Understanding what the model can see — and what it has already forgotten — explains almost every disappointing answer you will get.
The concept
Grok answers from its training data unless live access is on, and it will not always say which it used. This is the machinery. A model does not remember your last conversation the way a person does; it is handed text and asked to continue it well. Everything you want it to know has to be in that text, in the same window.
There is a difference between a system instruction — the standing context, set once — and a message, which is this request. Put your standing context in the standing place. "I am a final-year mechanical engineering student applying for data roles" belongs in your profile, not typed again at the start of every chat.
And there is a hard limit. When a conversation gets long enough, the earliest turns fall out of view. Symptoms: it contradicts an instruction you gave ten messages ago, or forgets the file you uploaded. The fix is a new conversation with a written summary of where you got to, not a longer argument.
Worked example
Ask about something released last week with search off and you may get a fluent answer built from nothing. With it on you get the actual posts.
Your practice task
Ask the same question twice: once on its own, once after a short paragraph of setup about who you are and what you need. Compare the two answers and write down the difference. That gap is the thing you are learning to control.
Do this before moving on. Reading a solution teaches the shape of it; typing it teaches you.
Key takeaway
Grok answers from its training data unless live access is on, and it will not always say which it used.
