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, Kimi K2 is cheaper on combined input and output, but real routing, discounts, and limits still matter.

Kimi K2 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.

  • Kimi K2 is worth checking first when the Kimi family, 200K context, and text->text capability match the job.
  • GLM 4.6 Air is worth checking first when the GLM family, 128K 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.

  • Moonshot AI: Kimi K2, Kimi, text->text
  • Zhipu AI (GLM): GLM 4.6 Air, GLM, text->text

  • GLM 4.6 Air: 更适合高频调用和渠道场景。
