Pixiu AI 网关将输入统一为openai格式，通过一个适配器filter转换成对应的供应商的格式

```mermaid
graph TD
    subgraph "客户端 (Client)"
        UserRequest("👤 用户/客户端")
    end

    subgraph "AI 网关 (AI Gateway)"
        A["入口: 接收标准OpenAI格式请求"]
        B{"选择对应的适配器"}
        
        subgraph "适配层 (Adapter Layer)"
            C1["适配器: OpenAI (透传)"]
            C2["适配器: Anthropic Claude"]
            C3["适配器: Google Gemini"]
            C4["适配器: ...更多"]
        end

        A --> B
        B -- "model: 'gpt-4o'" --> C1
        B -- "model: 'claude-3-opus-20240229'" --> C2
        B -- "model: 'gemini-1.5-pro'" --> C3
    end

    subgraph "LLM 供应商 (LLM Providers)"
        D1[☁️ OpenAI API]
        D2[☁️ Anthropic API]
        D3[☁️ Google AI API]
    end

    C1 --> D1
    C2 --> D2
    C3 --> D3
