PromptToExpressionBehavior.Temperature Property

Gets or sets the balance between creativity and consistency in AI responses. This is a dependency property.

Namespace: DevExpress.AIIntegration.Wpf

Assembly: DevExpress.AIIntegration.Wpf.v26.1.dll

Declaration

C#

public float? Temperature { get; set; }

VB.NET

Public Property Temperature As Single?

Property Value

Type	Description
Nullable<Single>	The balance between creativity (1.0) and consistency (0) in AI responses.

Remarks

The Temperature property controls the randomness of the output. The lower the temperature (starting with 0), the more predictably and focused the output is generated; higher temperatures (up to 1) result in more diverse and creative responses.

Note

Set the Temperature property to 1 for models (for example, GPT-5, o1, and o3 series) that ignore this parameter to avoid compatibility errors.

The following example sets the Temperature property to 0.3, so the AI generates more focused and deterministic responses (compared to the default temperature at 0):
