      summary: Compare models side by side
      description: 'An N-model comparison matrix across lifecycle, cost, and performance. Lifecycle and cost fields are available to every key; performance fields (capability class, speed, latency) are benchmark-derived and included only for paid keys. Free keys receive `performanceUnlocked: false` and null performance fields. Each entry may be a canonical id, an alias, or the bare API model string; references that resolve to the same model collapse into one column, and unmatched references are omitted.'
