# Inference Parameters
Different from `LLamaModel`, when using an exeuctor, `InferenceParams` is passed to the `Infer` method instead of constructor. This is because executors only define the ways to run the model, therefore in each run, you can change the settings for this time inference.
# InferenceParams
Namespace: LLama.Common
```csharp
public class InferenceParams
```
Inheritance [Object](https://docs.microsoft.com/en-us/dotnet/api/system.object) → [InferenceParams]()
