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

o4-mini 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.

  • o4-mini is worth checking first when the o-series family, 200K context, and text+image->text capability match the job.
  • ERNIE 4.5 Turbo is worth checking first when the ERNIE 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.

  • OpenAI: o4-mini, o-series, text+image->text
  • Baidu Wenxin: ERNIE 4.5 Turbo, ERNIE, text->text

Commercial fit

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

  • o4-mini: 适合推理型产品化调用和代理场景。
  • ERNIE 4.5 Turbo: 适合高频问答和中国企业助手场景。
