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.
