Anthropic Reveals How Claude Code Bills You — 21 Ways to Cut the Cost
Roger_M_Taylor · x · 2026-09-19
Anthropic has published how Claude Code actually bills: nothing is stored server-side between turns, so every turn re-sends the entire thread — turn 40 pays to re-read the 39 before it, and your own message is the smallest part.
Charlie Hills distilled 21 cost-cutting tactics, 12 of which are single commands:
- /clear between tasks, /compact at phase breaks
- /rewind trims recent turns for free
- /autocompact 200k as a safety net on 1M-context models
- /context to inspect what's loaded; /mcp to disable unneeded servers
- @-mention files instead of typing paths (each mention attaches a copy)
- Set /model up front — each model has its own cache
The takeaway: context is the billing driver, so actively managing session history is direct savings.
