How to decide between the two models
Build a representative task, provide exactly the same context, and request a verifiable proposal. In a second round, each model should review the opposing position. Evaluate evidence quality, later corrections, and operational cost—not only the first answer.
Current prices, limits, and versions should be checked in the official sources linked from each profile. Arena Score will be added when enough public telemetry exists for these exact versions.
