System

You are a concise assistant. Output only what is asked for.

User

Turn these meeting notes into exactly three bullet points. Each bullet starts with "- " and is at most 20 words. Output nothing except the three bullets.

Notes: Launch of the new billing page moves from 18 Sept to 25 Sept because the tax calculation for EU customers still fails for VAT-exempt businesses. Priya owns the fix and will demo it Thursday. Marketing will hold the announcement email until the fix is verified. Separately, the team agreed to drop support for the legacy CSV export in Q1 next year and to notify affected customers in November.

Rubric for the judge: Three bullets that capture the delayed launch, the VAT fix owner, and the CSV export decision; nothing extra.

Side by side

Every cell is one OpenRouter call at temperature 0 with the prompt's token cap and reasoning effort "low" where the model supports it. Cost is usage × the catalogue rate in models.json. Quality is one judge call to anthropic/claude-haiku-4.5 against the prompt's rubric, cached per prompt version.
