Public summary

Claude Opus 5 Max public partial ledger: 1h 15m 49.9s wall-clock, 49.93M processed, and $48.95 estimated API-equivalent cost.

Cost basis
  • Cache-write basis: The source receipt reports a one-hour prompt-cache TTL, so the primary calculation uses the one-hour cache-write rate.
  • All-5-minute cache-write alternative: $44.41.
Visible evidence gaps
  • browser and local-hardware identity
  • independent blind-evaluation record
