Observed Codex adapter elapsed time and estimated token cost stay distinct
Time is observed Codex adapter elapsed time. Cost is a versioned estimate from covered token aggregate usage and the official OpenAI API pricing documentation, accessed 2026-08-02. It is not actual Codex subscription billing or necessarily an exact API invoice.

- Formula
- Uncached input = total input − cache-read input − cache-write input. Multiply uncached input, cache-read input, cache-write input, and output by their versioned standard per-token rates, then sum them. Reasoning tokens are nested within output and are not added twice.
- Coverage
- Raw token counters are provider-reported. The verifier recomputes aggregates and the exact cost estimate from those counters when token coverage is complete. Prompts above 272,000 input tokens use 2× input and 1.5× output rates. Aggregate counters cannot identify which requests crossed that threshold, so AIQ displays a published-rate range: all-standard rates as the lower bound and the full long-context uplift as the upper bound. The range is not an exact invoice. Missing, invalid, or JCS-overflowed aggregate usage remains unavailable, never zero.
- Observed Codex adapter elapsed time
- Sum, median, and p95 of Codex adapter elapsed time: model plus allowed tools. It excludes workspace setup, artifact sealing, and evaluator replay. Runtime-issue tasks consume time; missing or non-invoked cells do not. Full-matrix timings are operational resource-profile evidence under the recorded node, execution order, and concurrency shown with each run. Model, tool, network, and local contention vary. This is not pure task latency or an isolated API-frontier latency test. Cell durations can overlap under concurrency. Signed matrix-stage start and finish times provide the full batch wall-clock, which is counted once across the 17 configurations. TTFT and TPS are unavailable and are not inferred.
- Interpretation
- AIQ, observed adapter elapsed time, and estimated API-equivalent USD remain separate. Scatter and Pareto context do not create a combined ranking.
