The prompt (verbatim, sent to every lane)
A meetup lands on the third Wednesday of September 2026. What is the date? Reply in YYYY-MM-DD format only.
Live runs are switched off right now — replays (recorded 2026-07-12) are the whole show today.
How scoring works
Exactly one YYYY-MM-DD token in the output, equal to 2026-09-16. Two candidate dates, or none in ISO format, fail. Scoring strips leading/trailing whitespace and one wrapping pair of code fences or quotes before it judges — content over ceremony. Winner rule: correct → cheapest → fastest.
Prices as listed by OpenAI and Anthropic, July 2026. Costs come from provider usage fields × list prices — nothing is invented.
