Google Gêmeos

O Google Gemini pode apoiar um agente Agent Framework através da Gemini Developer API ou da Vertex AI. O cliente específico do fornecedor gere as opções de autenticação e pedidos Gemini, enquanto o Agent Framework detém a definição e orquestração do agente.

Importante

O Google Gemini e o Vertex AI são sistemas de terceiros. Revise os termos do serviço, o tratamento dos dados, os limites regionais, o acesso ao modelo e os custos de utilização antes de enviar os dados da aplicação.

Instalar um Gemini IChatClient

O exemplo .NET demonstra o cliente oficial Google GenAI e a implementação da comunidadeMscc.GenerativeAI.Microsoft.

dotnet add package Google.GenAI
dotnet add package Mscc.GenerativeAI.Microsoft
dotnet add package Microsoft.Agents.AI --prerelease

Configuration

GOOGLE_GENAI_API_KEY="<google-ai-studio-api-key>"
GOOGLE_GENAI_MODEL="gemini-2.5-flash"

const string JokerInstructions = "You are good at telling jokes.";
const string JokerName = "JokerAgent";

string apiKey = Environment.GetEnvironmentVariable("GOOGLE_GENAI_API_KEY") ?? throw new InvalidOperationException("Please set the GOOGLE_GENAI_API_KEY environment variable.");
string model = Environment.GetEnvironmentVariable("GOOGLE_GENAI_MODEL") ?? "gemini-2.5-flash";

// Using a Google GenAI IChatClient implementation

ChatClientAgent agentGenAI = new(
    new Client(vertexAI: false, apiKey: apiKey).AsIChatClient(model),
    name: JokerName,
    instructions: JokerInstructions);

AgentResponse response = await agentGenAI.RunAsync("Tell me a joke about a pirate.");
Console.WriteLine($"Google GenAI client based agent response:\n{response}");

// Using a community driven Mscc.GenerativeAI.Microsoft package

ChatClientAgent agentCommunity = new(
    new GeminiChatClient(apiKey: apiKey, model: model),
    name: JokerName,
    instructions: JokerInstructions);

response = await agentCommunity.RunAsync("Tell me a joke about a pirate.");
Console.WriteLine($"Community client based agent response:\n{response}");

Escolha uma IChatClient implementação e configure a sua API de Desenvolvimento Gemini ou a autenticação Vertex AI.

Instale o pacote

pip install agent-framework-gemini --pre

Configuration

Use a API de Desenvolvedores Gemini:

GEMINI_API_KEY="<api-key>"
GEMINI_MODEL="gemini-2.5-flash"
# GOOGLE_API_KEY and GOOGLE_MODEL are also supported.

Ou configurar o Vertex AI:

GOOGLE_GENAI_USE_VERTEXAI="true"
GOOGLE_CLOUD_PROJECT="<project-id>"
GOOGLE_CLOUD_LOCATION="us-central1"
GOOGLE_MODEL="gemini-2.5-flash"

GeminiChatClient Suporta streaming, ferramentas funcionais, output estruturado, pensamento alargado e ferramentas alojadas pelo fornecedor.

async def non_streaming_example() -> None:
    """Runs the agent and waits for the complete response before printing it."""
    print("=== Non-streaming ===")

    # 1. Create the agent with the Gemini chat client and local weather tool.
    agent = Agent(

        instructions="You are a helpful weather agent.",

    query = "What's the weather like in Karlsruhe, Germany?"

    # 2. Ask a multi-location question and stream the model output as it arrives.
    query = "What's the weather like in Portland and in Paris?"
    print(f"User: {query}")
    print("Agent: ", end="", flush=True)
