Public summary
Claude Opus 5 Max public partial ledger: 1h 23m 18.7s wall-clock, ≥138.89M processed, and ≥$104.53 estimated API-list-price equivalent (lower bound).
Cost basis
- Transcript usage.cache_creation reports ephemeral_1h_input_tokens = 2,182,711 and ephemeral_5m_input_tokens = 0, i.e. 100% one-hour writes, billed at 2x base input.
- The token snapshot was taken while the session was still growing (401 of an eventual 409 assistant turns).
- The committed ledger qualifies this cost as a lower bound.
Visible evidence gaps
- blind-evaluation record
- standardized FPS and hitch receipt under sustained play
- scored side-by-side against the reference run's judging anchors
