Public summary

GPT-5.6 Luna Max partial_token_timing_source_and_build_ledger ledger: 22m 48s wall-clock, 7.05M processed, and $0.25 API-equivalent estimate, not a subscription invoice.

Run identity and stack
  • Result ID: space-flight-game-gpt-5.6-luna-max
  • Technical model: gpt-5.6-luna
  • Provider: OpenAI Codex
  • Stack: OpenAI Codex
  • Stack: Technical model/configuration: gpt-5.6-luna
  • Stack: Three.js / Vite game
  • Stack: Generated spaceship assets
  • Stack: Harness v1 space-flight prompt
Cost basis
  • Cache-creation is zero because the Codex transcript schema did not expose a cache-write field; no cache-write amount was inferred.
  • Default service-tier pricing.
  • Prompts with more than 272,000 input tokens use long-context pricing; all 82 supplied calls were short-context.
  • No cache-write amount was inferred from the supplied transcript schema.
  • Separately priced tools and non-token services are excluded.
Primary artifact integrity
  • Kind: interactive-threejs-space-flight-game
  • Path: artifacts/space-flight-game-gpt-5.6-luna-max/source/app/page.tsx
  • SHA-256: ae64b2a75324215ee2d9e821e5211a4d4109be07791bdfd5eececf6050836db3
Recorded caveats
  • Wall-clock is end-to-end workflow latency, not model-only compute; it includes tool time and idle gaps between user turns.
  • Output tokens include hidden reasoning, visible prose/code, and tool-call JSON.
  • Cached input is deeply discounted, so total processed tokens overstate cost.
  • This is an API-equivalent default-tier estimate rather than the actual charge for a subscription-backed Codex session.
  • Separately priced tools and non-token services are excluded.
  • The archive build check does not establish interactive frame rate or visual quality.
Visible evidence gaps
  • browser and local-hardware identity
  • local FPS
  • final capture
  • blind-evaluation record
