Frequently Asked Questions

Practical checks before selecting a production model.

Is Gemini 1.5 Pro better than Claude 3.7 Sonnet?

It depends on the workload. Gemini 1.5 Pro and Claude 3.7 Sonnet differ in pricing, context window, and capability mix — see the side-by-side table above for the breakdown.

What's the price difference between Gemini 1.5 Pro and Claude 3.7 Sonnet?

Gemini 1.5 Pro: N/A per 1M input tokens. Claude 3.7 Sonnet: $3.00 per 1M input tokens. Output token pricing typically runs 2-5x higher.

Which model is better for coding?

Coding preference depends on your stack and tool-calling needs. Compare the coding signal row, test with your repository tasks, and validate latency in your target region.

Which model is cheaper at scale?

Input and output token pricing can diverge by workload profile. Use the estimator with your monthly request count and token mix to get a realistic cost difference.

Are these official benchmark numbers?

Pricing is live from OpenRouter. Benchmark rows are ModelsAtlas metadata-based signals and should be treated as directional guidance, not official leaderboard scores.
