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.
- GLM 4.5V is worth checking first when the GLM Vision family, 128K context, and text+image->text capability match the job.
