快速入門

這份指南將協助您在專案中開始使用 Koog。

先決條件

確保您的環境與專案符合以下需求:

  • JDK 17+

  • Kotlin 2.2.0+

  • Gradle 8.0+ 或 Maven 3.8+

安裝 Koog

Koog 軟件包 新增為相依性:


dependencies {

    // 穩定版

    implementation("ai.koog:koog-agents:1.2.0")

    // Beta

    implementation("ai.koog:koog-agents-additions:1.2.0-beta")

}

dependencies {

    // 穩定版

    implementation 'ai.koog:koog-agents:1.2.0'

    // Beta

    implementation 'ai.koog:koog-agents-additions:1.2.0-beta'

}
xml

<dependency>

    <!-- 穩定版 -->

    <dependency>

        <groupId>ai.koog</groupId>

        <artifactId>koog-agents-jvm</artifactId>

        <version>1.2.0</version>

    </dependency>

    <!-- Beta -->

    <dependency>

        <groupId>ai.koog</groupId>

        <artifactId>koog-agents-additions-jvm</artifactId>

        <version>1.2.0-beta</version>

    </dependency>

</dependency>
模組版本控制

Koog 遵循語義化版本(Semantic Versioning,X.Y.Z)。穩定模組(例如 1.0.0)保證 API 的穩定性,而 Beta 模組(例如 1.0.0-beta)是實驗性的,在不同版本之間可能會發生變化。

詳情請參閱 模組版本控制

Nightly 版本

來自 develop 分支的 Nightly 版本會發佈到 JetBrains Grazie Maven 存儲庫。

若要使用 Nightly 版本,請將以下存儲庫新增到您的組建組態: https://packages.jetbrains.team/maven/p/grazi/grazie-platform-public

接著將您的 Koog 相依性更新為所需的 Nightly 版本。Nightly 版本遵循以下模式: [next-major-version]-develop-[date]-[time]

您可以在這裡瀏覽可用的 Nightly 版本。

設定 API 金鑰

Koog 需要來自受支援的 LLM 提供者的 API 金鑰,或是本機執行的 LLM。

Warning

避免在原始碼中硬編碼 API 金鑰。 請使用環境變數來儲存 API 金鑰。

取得您的 OpenAI API 金鑰 並將其指派給 OPENAI_API_KEY 環境變數。

shell
export OPENAI_API_KEY=your-api-key
cmd
setx OPENAI_API_KEY "your-api-key"

取得您的 Anthropic API 金鑰 並將其指派給 ANTHROPIC_API_KEY 環境變數。

shell
export ANTHROPIC_API_KEY=your-api-key
cmd
setx ANTHROPIC_API_KEY "your-api-key"

取得您的 Gemini API 金鑰 並將其指派給 GOOGLE_API_KEY 環境變數。

shell
export GOOGLE_API_KEY=your-api-key
cmd
setx GOOGLE_API_KEY "your-api-key"

取得您的 DeepSeek API 金鑰 並將其指派給 DEEPSEEK_API_KEY 環境變數。

shell
export DEEPSEEK_API_KEY=your-api-key
cmd
setx DEEPSEEK_API_KEY "your-api-key"

取得您的 OpenRouter API 金鑰 並將其指派給 OPENROUTER_API_KEY 環境變數。

shell
export OPENROUTER_API_KEY=your-api-key
cmd
setx OPENROUTER_API_KEY "your-api-key"

產生 Amazon Bedrock API 金鑰 並將其指派給 BEDROCK_API_KEY 環境變數。

shell
export BEDROCK_API_KEY=your-api-key
cmd
setx BEDROCK_API_KEY "your-api-key"

取得您的 Mistral API 金鑰 並將其指派給 MISTRAL_API_KEY 環境變數。

shell
export MISTRAL_API_KEY=your-api-key
cmd
setx MISTRAL_API_KEY "your-api-key"

按照 Ollama 文件中的說明,在 Ollama 中執行本機 LLM。

建立您的第一個 Koog Agent

以下範例透過 OpenAI API,使用 GPT-4o 模型建立並執行一個簡單的 Koog Agent。

kotlin
fun main() = runBlocking {
    // 從 OPENAI_API_KEY 環境變數取得 OpenAI API 金鑰
    val apiKey = System.getenv("OPENAI_API_KEY")
        ?: error("The API key is not set.")

    // 建立 Agent
    val agent = AIAgent(
        promptExecutor = MultiLLMPromptExecutor(OpenAILLMClient(apiKey)),
        llmModel = OpenAIModels.Chat.GPT4o
    )

    // 執行 Agent
    val result = agent.run("Hello! How can you help me?")
    println(result)
}
java
// 從 OPENAI_API_KEY 環境變數取得 OpenAI API 金鑰
String apiKey = System.getenv("OPENAI_API_KEY");
if (apiKey == null) {
    throw new RuntimeException("The API key is not set.");
}

// 建立 Agent
AIAgent<String, String> agent = AIAgent.builder()
    .promptExecutor(new MultiLLMPromptExecutor(openAIClient(apiKey)))
    .llmModel(OpenAIModels.Chat.GPT4o)
    .build();

// 執行 Agent
String result = agent.run("Hello! How can you help me?");
System.out.println(result);

該範例可能會產生以下輸出:

AIAgent<String, String> agent = AIAgent.builder()
    .promptExecutor(new MultiLLMPromptExecutor(anthropicClient(apiKey)))
    .llmModel(AnthropicModels.Opus_4_1)
    .build();

// 執行 Agent
String result = agent.run("Hello! How can you help me?");
System.out.println(result);

該範例可能會產生以下輸出:
