DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.221

Token usage totals now include cache tokens

You'll notice
Useful4 Signal0
Usage & Limits

Your usage totals now include cache reads and writes, so numbers look higher but accurate.

What

Per-day and per-model usage totals now count cache traffic, so rolled-up figures no longer understate sessions that hit the cache.

Details
  • the accumulated value changed from input+output tokens to input+output+cache-read+cache-creation tokens
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
