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, DeepSeek R1 0528 is cheaper on combined input and output, but real routing, discounts, and limits still matter.

GPT-5.4 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.

  • GPT-5.4 Mini is worth checking first when the GPT-5.4 family, 400K context, and text+image+file->text capability match the job.
  • DeepSeek R1 0528 is worth checking first when the R1 family, 163.8K 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: GPT-5.4 Mini, GPT-5.4, text+image+file->text
  • DeepSeek: DeepSeek R1 0528, R1, text->text

Commercial fit

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

  • GPT-5.4 Mini: 高性价比主力通用模型,适合规模化生产环境。
  • DeepSeek R1 0528: 推理能力强,是中国站高热度推理模型入口之一。
