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, ERNIE 4.5 300B A47B is cheaper on combined input and output, but real routing, discounts, and limits still matter.

Step-2 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.

  • ERNIE 4.5 300B A47B is worth checking first when the ERNIE family, 123K context, and text->text capability match the job.
  • Step-2 is worth checking first when the Step family, 256K 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.
