Key implications
Insufficient shared-metric coverage. Each finding is tied to a published metric, price, context, or modality fact.
- Input API price: GLM-5.2 has the lower verified rate ($1.4 / 1M tokens vs $5 / 1M tokens).
- Output API price: GLM-5.2 has the lower verified rate ($4.4 / 1M tokens vs $30 / 1M tokens).
Shared metric view
A radar is shown only when at least four compatible supported score metrics are published.
