Question 1

What is a context window in AI?

Accepted Answer

The context window is how much text an AI can keep in mind at once: your messages, its replies and any files. Anything that doesn't fit is forgotten.

Question 2

What is a real-life example of context window?

Accepted Answer

Like a whiteboard in a meeting: when it's full, the oldest notes are wiped to make room, and nobody remembers them.

Question 3

In a very long chat, the AI forgets something you said at the start. Why?

Accepted Answer

When a chat outgrows the context window, the oldest parts no longer fit, so the AI can't see them any more.

Question 4

What counts toward the context window?

Accepted Answer

Everything in the conversation takes up space: what you write, what the AI writes, and any documents you attach.

Question 5

You need the AI to keep key facts in mind during a long project chat. What helps most?

Accepted Answer

Restating the key facts, or starting a fresh chat with a short summary, puts them back inside the context window.
