Comparison summary

How to choose first

This is a cross-provider comparison. Start with the job boundary, then verify what your key can actually see.

On the listed price snapshot, Yi Lightning is cheaper on combined input and output, but real routing, discounts, and limits still matter.

Gemini 2.5 Pro has the larger context window, which helps with long documents, knowledge bases, logs, and multi-turn workflows.

Decision boundary

Do not start with which model is absolutely stronger. Start with the boundary: cost, context, speed, quality, ecosystem, or supply stability.

  • Gemini 2.5 Pro is worth checking first when the Gemini family, 1M context, and text+image+file->text capability match the job.
  • Yi Lightning is worth checking first when the Yi family, 200K context, and text->text capability match the job.

Key checking route

If you already hold a key, the valuable check is provider identity, callable models, and whether balance, limits, or subscription status are visible.

  • Google: Gemini 2.5 Pro, Gemini, text+image+file->text
  • 01.AI / Yi: Yi Lightning, Yi, text->text

Commercial fit

Commercially, do not look at model names alone. Combine price, limits, region, upstream stability, and ongoing monitoring.

  • Gemini 2.5 Pro: 企业多模态和搜索增强场景常用型号。
  • Yi Lightning: 适合“国产高性价比模型”这类长尾入口。
