Key implications
Insufficient shared-metric coverage. Each finding is tied to a published metric, price, context, or modality fact.
- Input API price: Gemini 3.1 Pro has the lower verified rate ($2 / 1M tokens vs $2.5 / 1M tokens).
- Output API price: Gemini 3.1 Pro has the lower verified rate ($12 / 1M tokens vs $15 / 1M tokens).
- Context window: GPT-5.6 Terra has the larger published context window (1,050,000 tokens vs 1,000,000 tokens).
Shared metric view
A radar is shown only when at least four compatible supported score metrics are published.
