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, Llama 4 Scout is cheaper on combined input and output, but real routing, discounts, and limits still matter.

When context is similar, compare output quality, API stability, limits, and actually callable models first.

Decision boundary

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

  • Gemini 3.1 Pro Preview is worth checking first when the Gemini family, 1M context, and text+image+file+audio+video->text capability match the job.
  • Llama 4 Scout is worth checking first when the Llama family, 1M context, and text+image->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.

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