🏆 Quality winner: openrouter:deepseek/deepseek-v4-pro
2eb734 combines the most precise, mechanism-matched analogies (Cold War Tu-4 reverse-engineering directly parallels distillation that copies but doesn't fully match), a complete and polished four-paragraph reading passage, a full 10-question set with correct evidence-pairing, and the richest accurate glossary. 0313fc is comparably strong but its rewritten passage is cut off mid-sentence, and a0132a offers only 3 quiz questions and a shorter passage.
💰 Best value: openrouter:deepseek/deepseek-v4-pro
— quality 9/10 at 0.62¢ → value 8.7/10
Value = 0.7·quality + 0.3·cheapness. Quality stays dominant, so a cheap-but-weak output can't win on price alone.

Excellent mechanism-matched analogies (Tu-4/B-29 reverse-engineering, term-paper paraphrasing, open-source forking). Ten well-constructed SAT-style questions including proper evidence-pairing. Rich glossary and a polished, accurate, multi-paragraph passage. Facts carefully grounded with dates. |

Very strong, faithful, and well-organized with good analogies (arms race, doping scandal) and 10 fair questions with evidence-pairing. Passage appears truncated at the end ('respon'). Slightly behind the winner on analogy depth and passage completeness. |

Solid and faithful with good analogies (chef's recipe, generic drug). Only 3 quiz questions where competitors offer 10 with evidence-pairing; Q2 answer 'replicate' vs 'condense' is a bit arguable. Passage is accurate and engaging but compresses heavily. |
