Token economics
| Token type | Price | vs base input |
|---|---|---|
| Standard input | $0.375 | — |
| Cache read | $0.037 | −90% |
| Output | $2.25 | — |
| Web search tool | $10/1k searches | — |
Prompt caching stores repeated context server-side: reads cost far less, but writes carry a one-time premium.
Higher effort = deeper thinking = more reasoning tokens billed as output.
