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.

Usage stats now count and show cache tokens

Usage & Limits

Usage stats now count cache tokens and show a read/write breakdown per model.

/usage
What

Token totals on the stats screens include cache traffic, which changes the headline number, the favorite-model ordering and each model's share percentage.

Details
  • The per-model scoring helper now sums inputTokens, outputTokens, cacheReadInputTokens and cacheCreationInputTokens; previously it was input plus output only.
  • A breakdown line is appended to the text summary in the form Input … · Output … · Cache read … · Cache write …, assembled at runtime from fixed fragments.
  • Each of the top three models gains a second dim line built from the fragments Cache: , read \xB7 and write.
  • Neither the summary line nor the per-model line exists in 2.1.220.
Evidence

Cache read ${od(n)} \xB7 Cache write ${od(o)}

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