Public summary

GPT-5.6 Terra Ultra partial_token_timing_and_artifact_ledger ledger: 16:43.2 wall-clock, 1.34M processed, and $1.20 API-equivalent estimate, not a subscription invoice.

Run identity and stack
  • Result ID: jungle-temple-gpt-5.6-terra-ultra
  • Technical model: gpt-5.6-terra
  • Provider: OpenAI Codex
  • Stack: OpenAI Codex
  • Stack: Technical model/configuration: gpt-5.6-terra
  • Stack: Blender MCP
  • Stack: 0.05-unit voxel grid
  • Stack: Inspectable .blend artifact
Cost basis
  • Requests with more than 272,000 input tokens use long-context pricing; all 19 supplied calls were short-context.
  • Separately priced tools and non-token services are excluded.
Primary artifact integrity
  • Kind: blender-scene
  • Path: artifacts/jungle-temple-gpt-5.6-terra-ultra/jungle_temple_diorama.blend
  • SHA-256: 022461495e61ff3cf63f108f69f3d9a6bba799f9b4f8d40cb9dc0a6515a26c54
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
  • Blender and render environment
  • final capture metadata
  • blind-evaluation record
