Public summary

GPT-5.6 Sol Ultra partial_token_timing_and_source_ledger ledger: 23:08.4 wall-clock, 8.72M processed, and $6.86 API-equivalent estimate, not a subscription invoice.

Run identity and stack
  • Result ID: campfire-threejs-gpt-5.6-sol-ultra
  • Technical model: gpt-5.6-sol
  • Provider: OpenAI Codex
  • Stack: OpenAI Codex
  • Stack: Technical model/configuration: gpt-5.6-sol
  • Stack: Three.js interactive scene
  • Stack: Harness v1 campfire prompt
Cost basis
  • Requests with more than 272,000 input tokens use long-context pricing; all 106 supplied calls were short-context.
  • Separately priced tools and non-token services are excluded.
Primary artifact integrity
  • Kind: threejs-campfire-primary-source
  • Path: artifacts/campfire-threejs-gpt-5.6-sol-ultra/source/app/CampfireScene.tsx
  • SHA-256: d4ff395b603ba22047b748e7f607b32df2efa411069f963a73006178d0ecf72f
Recorded caveats
  • Wall-clock is end-to-end 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 estimate rather than the actual charge for a subscription-backed Codex session.
  • Separately priced tools and non-token services are excluded.
  • Cache-creation tokens are zero because the Codex transcript schema does not expose a cache-write field.
  • Subagent logs are excluded to avoid double-counting inherited parent context.
Visible evidence gaps
  • browser and hardware environment
  • local FPS
  • final capture
  • blind-evaluation record
