GPT-5.5 vs GPT-5.4: Which Should You Use?

Описание: GPT-5.5 vs GPT-5.4 is not just a benchmark question. It is a workbench decision about cost, quality, and the job in front of you.

In this visual guide, we compare GPT-5.5 and GPT-5.4 using OpenAI's release data, API pricing, and practical routing rules. The point is not to crown the newest model for every task. The point is to know when GPT-5.4 is the economical professional default, and when GPT-5.5 is worth the upgrade for coding, research, documents, tool use, and high-stakes workflows.

You'll learn why sticker price is not always job price, why short everyday prompts may not reveal the difference, and how to think about GPT-5.5 Pro for maximum-care work.
