Workflow Update: GPT Action Enhancement

We’ve streamlined the GPT Action experience for the latest GPT-5 model family by OpenAI.

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

These models have a hardcoded temperature value of 1 set by OpenAI, meaning they do not support custom temperature settings. We’ve updated the UI to reflect this, providing you with a cleaner configuration experience featuring only the options applicable to your selected model.

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