Does using more of the context window cost more?
Yes. Every input token is billed, so a request with 500K tokens of context costs far more than one with 5K. And once a prompt is over 262K tokens, its whole input bills at 1.5×. See long-context pricing.
Big windows are great when you need them; most questions don't.
