Cache reads are billed at 0.1× the input rate, so they dominate the token count but barely the cost. Output is the priciest per token.

Where the cache reads go (the prefix, re-read every round)

The system prompt + tool schemas are re-sent (cached) on every tool-loop round. A turn calling N tools does N+1 rounds, so this is the lever for the big token counts — fewer tools sent (tier-aware) and fewer rounds (combined tools) cut it directly.
