Public summary

GPT-5.6 Terra Ultra partial_token_timing_and_artifact_ledger ledger: 16:35.1 wall-clock, 5.76M processed, and $3.27 API-equivalent estimate, not a subscription invoice.

Run identity and stack
  • Result ID: neo-gothic-storm-city-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: TWIGL fragment shader
  • Stack: Harness v1 neo-gothic storm city prompt
Cost basis
  • Requests with more than 272,000 input tokens use long-context pricing; all 46 supplied calls were short-context.
  • Separately priced tools and non-token services are excluded.
Primary artifact integrity
  • Kind: twigl-classic-fragment-shader
  • Path: artifacts/neo-gothic-storm-city-gpt-5.6-terra-ultra/shader.frag
  • SHA-256: ef652dc1b3587a781c03b29f09d70b6bf4aae3a32fc69a1b3d2c5b1e0e7736e4
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.
