🏆 Quality winner: anthropic:claude-opus-4-8

Run 83ff29 is far more faithful to the source—it hedges attribution to Bhalla, uses verifiable figures, and its analogies map tightly onto the reform-complacency mechanism. Run 705590 invents concrete facts (West Bengal win, 2015 exit clauses, 8th-place ranking, quiz explanations citing nonexistent lines) and its reading passage is barely more than a fragment, whereas 83ff29's is fuller and more engaging despite its own truncation.

💰 Best value: anthropic:claude-opus-4-8 — quality 8/10 at 17.06¢ → value 5.9/10

Value = 0.7·quality + 0.3·cheapness. Quality stays dominant, so a cheap-but-weak output can't win on price alone.

Quality ranking

#	Model	Facts	Analogy	Age-fit	Clarity	Quiz	Glossary	Passage	Overall	Cost	Value	Notes
🥇	`anthropic:claude-opus-4-8` view ↗	8	8	9	9	8	9	7	8	17.06¢	5.9	Strong grounding with specific figures (12% rupee fall, QCOs 14→765, Feb 2025 BIT review) that align well and are used consistently. The restaurant/kitchen and 'complain to the chef's own family' analogies genuinely share the topic's mechanism. Reading passage is engaging but appears cut off mid-sentence ('inflation is contained') with the 'agents' field oddly split, hurting passage coherence.
🥈	`anthropic:claude-haiku-4-5-20251001` view ↗	4	7	8	8	5	8	3	5	3.02¢	4.7	Introduces several likely-invented specifics: a 'West Bengal victory,' a '2015 BIT revision with exit clauses,' and a precise 'per capita GDP ranks 8th' figure that don't clearly derive from the other candidate's shared facts and read as fabricated. Analogies (student president, football team) are decent. The rewritten_passage is truncated to a single fragment, and several quiz explanations quote passage text that doesn't appear, undermining fairness.
