In plain English
- Reading 1,000 words costs $0.0027
- Writing 1,000 words costs $0.013
- One request (1,500 words in, 400 out) costs $0.0093
- $1 buys about 107 requests
57% of each request's cost is the reply. Output tokens usually cost several times more than input, so shorter replies save more than shorter prompts.
Estimates from list prices, last checked October 2026. Real bills also depend on hidden "thinking" or reasoning tokens (billed as output on most models), chat history resent on every turn, prompt caching and batch discounts (which can cut input costs a lot), and images or files.
