Review the inputs, then run to create a readable result and complete export. Editing cancels active work and clears stale results.
Formula, sources and limits
Step input = initial + (step−1) × added. Added must include any retained assistant output and tool results. Each step bills its entire input and output; no prompt cache or context truncation. Rates, limits, subscriptions and latency defaults are illustrative custom assumptions, not current vendor quotes or benchmarks. Check official sources and replace them. Each text field ≤32,768 UTF-16 units, total input ≤128 KiB, output ≤1 MiB; local job timeout 30s.
