Cost Model Based on Slot Time for Free AI Lanes
A simulation shows that queue time dominates over token cost in free AI lanes.

01Summary
Slot seconds, not tokens, are the true cost metric. Retries increase slot overhead and risk data duplication. Key thresholds include success rate, retry overhead, and p90 wait time. A gate should be placed before dispatch to prevent queue buildup.
Summarised from the original article by an open-source model, then checked automatically: every number and English name must appear in the source. The original article is authoritative.
02Key points
- Queue time dominates over token cost in free lanes
- Retries double slot overhead and cause data duplication
- p90 wait exceeds deadline slack: free lane is unsuitable
- Gate before dispatch to control queue growth
