Get

Gets a model by name

function : Get(model_name:String, key:String) ~ Model

Parameters

Name	Type	Description
model_name	String	model name
key	String	API key

Return

Type	Description
Model	available models

GetDescription

Get the model's description

method : public : GetDescription() ~ String

Return

Type	Description
String	model's description

GetDisplayName

Get the model's display name

method : public : GetDisplayName() ~ String

Return

Type	Description
String	model's display name

GetGenerationMethods

The model's supported generation methods.

method : public : GetGenerationMethods() ~ Vector<String>

Return

Type	Description
Vector<String>	generation methods

GetInputTokenLimit

Get the model's input token limit

method : public : GetInputTokenLimit() ~ Int

Return

Type	Description
Int	model's input token limit

GetName

Get the model's name

method : public : GetName() ~ String

Return

Type	Description
String	model's name

GetOutputTokenLimit

Maximum number of output tokens available for this model

method : public : GetOutputTokenLimit() ~ Int

Return

Type	Description
Int	maximum number of output tokens

GetTemperature

Controls the randomness of the output. Values can range over [0.0,1.0], inclusive. A value closer to 1.0 will produce responses that are more varied, while a value closer to 0.0 will typically result in less surprising responses from the model.
