Is this feature from Open AI supported by Semantic Kernel - force the model to always call one or more functions, you can set tool_choice: "required".

Is the below feature supported by Semantic Kernel?

To force the model to always call one or more functions, you can set tool_choice: "required". The model will then select which function(s) to call.

Thanks

@EVENFLOW212 Yes, it is supported by using ToolCallBehavior.RequireFunction() in execution settings:

semantic-kernel/dotnet/samples/Concepts/Filtering/AutoFunctionInvocationFiltering.cs

Lines 30 to 33 in d2bc3a8

	var executionSettings = new OpenAIPromptExecutionSettings
	{
	ToolCallBehavior = ToolCallBehavior.RequireFunction(function.Metadata.ToOpenAIFunction(), autoInvoke: true)
	};

As for now it accepts only one function, but we are working on new function calling abstractions that will accept multiple required functions to call.

Thank you!

Hi @dmytrostruk

We have multiple plugins and multiple functions for our client facing app.

Would you know what the timeline would be for the implementation of multiple required function calls?

Thanks

@EVENFLOW212, as @dmytrostruk said, we are currently working on the new function calling model - #6083 - and plan to go live with it around the second half of July.

Hi @dmytrostruk

Please let us know when this is implemented. We are using gpt-4o and does not seem that the azure open ai we are using supports this functionality yet.

Thanks

@EVENFLOW212 Multiple required function calls are now supported in latest version of Semantic Kernel. Here is an example, where the configuration accepts an array of functions:

semantic-kernel/dotnet/samples/Concepts/Filtering/AutoFunctionInvocationFiltering.cs

Lines 30 to 33 in f08cf3c

	var executionSettings = new OpenAIPromptExecutionSettings
	{
	FunctionChoiceBehavior = FunctionChoiceBehavior.Required([function], autoInvoke: true)
	};
