Gemini
Gemini 3.1 Pro
The reasoning tier — reach for it when the task is hard, not just long.
最适合
- Multi-step research that separates facts, inferences, and unknowns
- Multi-file code changes, reviews, and root-cause debugging
- Comparisons that weigh several criteria against real constraints
在以下情况使用它
- The answer depends on careful reasoning, not just recall.
- A mistake is expensive and you want the model to slow down.
- You need structured output (decision tables, comparison matrices).
在以下情况考虑其他档位
- The task is short and well-scoped — Flash is faster and cheaper.
- You are doing high-volume, low-stakes drafting.
搭配得当的提示词
- Turn a broad question into a cited decision brief
- Ship a feature without losing the existing architecture
- Get a code review that ranks issues by severity
