Public summary
GPT-5.6 Luna xhigh partial_token_timing_and_artifact_ledger ledger: 8:46.5 wall-clock, 526K processed, and $0.21 API-equivalent estimate, not a subscription invoice.
Run identity and stack
- Result ID: neo-gothic-storm-city-gpt-5.6-luna-xhigh
- Technical model: gpt-5.6-luna
- Provider: OpenAI Codex
- Stack: OpenAI Codex
- Stack: Technical model/configuration: gpt-5.6-luna
- 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 14 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-luna-xhigh/shader.frag
- SHA-256: 2ee245fd6fb7442cb30135524e56e2cda20a4082a6c231e591c8e7f4c2087659
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
- initial local FPS
- optimized local FPS
- RTX Pro 6000 1080p60 final capture
- blind-evaluation record
