⚡ Quick Start

1️⃣ Add Dependencies (Maven)

<dependency>
    <groupId>com.agentsflex</groupId>
    <artifactId>agents-flex-core</artifactId>
    <version>2.1.1</version>
</dependency>
<!-- Optional: Add extension modules as needed -->
<dependency>
    <groupId>com.agentsflex</groupId>
    <artifactId>agents-flex-mcp</artifactId>
    <version>2.1.1</version>
</dependency>

2️⃣ Hello World

public class QuickStart {
    public static void main(String[] args) {
        // 1. Configure the model (supports GiteeAI / OpenAI / Ollama, etc.)
        OpenAIChatModel chatModel = OpenAIChatConfig.builder()
            .provider("GiteeAI")
            .endpoint("https://ai.gitee.com")
            .requestPath("/v1/chat/completions")
            .apiKey(System.getenv("GITEE_AI_KEY")) // ✅ Recommended: load from environment variable
            .model("Qwen3-32B")
            .buildModel();

        // 2. Start a conversation (sync/streaming/async all supported)
        String response = chatModel.chat("Explain what humor is in a way that Java developers can understand?");

        // 3. Output the result
        System.out.println("🤖 Agents-Flex: " + response);
    }
}

Console Output Example:

[Agents-Flex] >>> [GiteeAI/Qwen3-32B] Request: {"model":"Qwen3-32B","messages":[...]}
[Agents-Flex] <<< [GiteeAI/Qwen3-32B] Response: 200 OK (1.2s)
🤖 Agents-Flex: Humor is like elegant exception handling in code—seemingly unexpected, yet meticulously designed...

📝 The [Agents-Flex] log prefix can be customized or disabled via application.properties. For production environments, SLF4J integration is recommended.

✅ Production-Ready Recommendations:

• Use agents-flex-spring-boot-starter with a configuration center for API key management in production
• Inject sensitive information (API Keys / DB passwords) via @Value("${xxx}") + encrypted configuration
• Enable management.endpoints.web.exposure.include=metrics,trace for monitoring integration
• For RAG scenarios, combine: data + embedding + store + rerank modules
