Harnesses

Same model, different drivers. ChatGPT is not OpenCode. $ / MU is only set when every official task passed. $ / pass still shows on a partial run; it does not rank. Time is output tokens at 80 tok/s, not wall clock.

Official jobs

Pass or fail on each sealed job. Attempts include retries. Failed tries stay in the bill.

Tokens by job

Billed tokens on each official job, including retries. Cache reads drop out of this count.

Where the bill goes

Failed attempts stay in the bill. Cache hits are a discount, shown separately.

Retry tax

Attempts are harness calls, including failed hidden-verifier retries. Extra tries stay in the bill.

Qwenmax3 attempts / 3 jobs

Cache hits

Hits divided by uncached input plus hits. No cache means the harness did not report a discount.

Encoding by slice

Native tokens per MU on the same frozen basket. Tool schemas are where fertility often doubles.
