Properties

Name	Required	Description
Title	No	The title of the action.
Connection	Yes	Defines the connection to OpenAI.
Model Id	Yes	The id of the model to be used, such as gpt-5.5, gpt-5.6, etc. This determines the capabilities and cost of the model.
Temperature	No	Temperature in models controls the randomness and creativity of the generated responses. Lower temperatures (e.g., 0.2) produce more focused, predictable text, ideal for tasks that require precision. Higher temperatures (e.g., 1.5) increase creativity and variability, but may risk generating less coherent or relevant content, making it important to adjust based on your desired outcome.
Max Tokens	No	Sets a limit on the number of tokens (words, characters, or pieces of text) in the model’s response.
Reasoning effort	No	Guides the model on how much to think when performing a task.
API type	No	Specifies which API type to use for the selected AI model. Valid values are Completions and Responses . You should not specify this property unless you want to change the default which is Responses
Description	No	Additional details or notes.
