We've streamlined the GPT Action experience for the latest GPT 5 model family by OpenAI

What Changed

When using any of the newer models mentioned below , the Advanced Options section with temperature is now hidden:

GPT-5

GPT-5 mini

GPT-5 nano

GPT-5.1

Why This Matters

These models have a hardcoded temperature value of 1 set by OpenAI, they simply don't support custom temperature settings. We've updated the UI to reflect this, giving you a cleaner configuration experience with only the options that apply to your selected model.

For all other models, Advanced Options with temperature control remain available as usual.
