});

OpenAIAgent agent = factory.CreateAgent(new OpenAIAgentOptionsForResponseApiWithReasoning
{
    Model = "gpt-5",
    ReasoningEffort = ResponseReasoningEffortLevel.High,
    ReasoningSummaryVerbosity = ResponseReasoningSummaryVerbosity.Detailed,    
});

Google

GoogleAgentFactory factory = new(new GoogleConnection
{
    ApiKey = configuration.GoogleGeminiApiKey
});

GoogleAgent agent = factory.CreateAgent(new GoogleAgentOptions
{
    Model = GenerativeAI.GoogleAIModels.Gemini25Pro,
    Tools = [AIFunctionFactory.Create(GetWeather)]
});

Anthropic

AnthropicAgentFactory factory = new AnthropicAgentFactory("<AnthropicApiKey">);

factory.CreateAgent(new AnthropicAgentOptions
{
    Model = "claude-sonnet-4-5",
    MaxOutputTokens = 10000, // <-- Force the MaxToken property I always forget
    BudgetTokens = 5000

});

XAIAgent agent = factory.CreateAgent(new OpenAIAgentOptionsForChatClientWithoutReasoning
{
    Model = "grok-4-fast-non-reasoning",

MistralAgent mistralAgent = mistralAgentFactory.CreateAgent(new MistralAgentOptions
{
    Model = Mistral.SDK.ModelDefinitions.MistralSmall
});

Azure AI (with every optional setting added for demonstration)

    Model = "gpt-5-mini",
    ReasoningEffort = ResponseReasoningEffortLevel.Low,
    ReasoningSummaryVerbosity = ResponseReasoningSummaryVerbosity.Detailed,
    Tools = [AIFunctionFactory.Create(GetWeather)],
    RawToolCallDetails = details => { Console.WriteLine(details.ToString()); },
    RawHttpCallDetails = details =>
    {
        Console.WriteLine($"URL: {details.RequestUrl}");
        Console.WriteLine($"Request: {details.RequestJson}");
        Console.WriteLine($"Response: {details.ResponseJson}");
