Rewrite this paragraph so a 12-year-old would understand it. Keep it under 70 words and do not use the words "leverage", "synergy" or "paradigm". Output only the rewritten paragraph. Paragraph: Our next-generation battery architecture leverages a solid-state electrolyte paradigm to achieve synergy between energy density and thermal stability, enabling a 40% increase in range while mitigating the combustion risk profile associated with legacy lithium-ion chemistries.
Rubric for the judge: Simple vocabulary, keeps the 40% range gain and the safety point, under 70 words, banned words absent.
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.
