🚀 Quick Start

Installation

Add to your Go project:

go get github.com/helixagent/toolkit/SiliconFlow/providers/siliconflow

Basic Usage

package main

import (
    "context"
    "log"

    "github.com/helixagent/toolkit/SiliconFlow/providers/siliconflow"
    "github.com/helixagent/toolkit/pkg/toolkit"
)

func main() {
    // Create provider configuration
    config := map[string]interface{}{
        "api_key": "your-siliconflow-api-key",
        "base_url": "https://api.siliconflow.com/v1",
        "timeout": 30000,
    }

    // Create provider instance
    provider, err := siliconflow.NewProvider(config)
    if err != nil {
        log.Fatal(err)
    }

    // Discover available models
    ctx := context.Background()
    models, err := provider.DiscoverModels(ctx)
    if err != nil {
        log.Fatal(err)
    }

    log.Printf("Discovered %d models", len(models))

    // Perform chat completion
    req := toolkit.ChatRequest{
        Model: "Qwen/Qwen2.5-7B-Instruct",
        Messages: []toolkit.ChatMessage{
            {Role: "user", Content: "Hello, how are you?"},
        },
        MaxTokens:   1000,
        Temperature: 0.7,
    }

    resp, err := provider.Chat(ctx, req)
    if err != nil {
        log.Fatal(err)
    }

    log.Printf("Response: %s", resp.Content)
}

API Client Features

The SiliconFlowProvider implements the full HelixAgent Toolkit Provider interface:

Chat Completions

req := toolkit.ChatRequest{
    Model: "Qwen/Qwen2.5-7B-Instruct",
    Messages: []toolkit.ChatMessage{
        {Role: "user", Content: "Explain quantum computing"},
    },
    MaxTokens:   2000,
    Temperature: 0.7,
}

resp, err := provider.Chat(ctx, req)

Embeddings

req := toolkit.EmbeddingRequest{
    Model: "text-embedding-ada-002",
    Input: []string{"Hello world", "How are you?"},
}

resp, err := provider.Embed(ctx, req)

Image Generation

// Note: Image generation support depends on available models
req := toolkit.ImageGenerationRequest{
    Model: "black-forest-labs/FLUX.1-dev",
    Prompt: "A beautiful sunset over mountains",
    Size: "1024x1024",
}

resp, err := provider.CreateImage(ctx, req)

Dynamic Model Discovery

The provider automatically discovers and categorizes models:

models, err := provider.DiscoverModels(ctx)
if err != nil {
    log.Fatal(err)
}

for _, model := range models {
    log.Printf("Model: %s (%s) - %s", model.Name, model.ID, model.Category)
    log.Printf("  Context Window: %d", model.Capabilities.ContextWindow)
    log.Printf("  Supports Vision: %v", model.Capabilities.SupportsVision)
}

🔧 Configuration

Provider Configuration

config := map[string]interface{}{
    "api_key":    "your-siliconflow-api-key",     // Required
    "base_url":   "https://api.siliconflow.com/v1", // Optional, defaults to SiliconFlow API
    "timeout":    30000,                          // Optional, milliseconds
    "retries":    3,                              // Optional
    "rate_limit": 60,                             // Optional, requests per minute
}

Integration with HelixAgent Toolkit

Register the provider with the toolkit:

tk := toolkit.NewToolkit()

// Register SiliconFlow provider factory
if err := siliconflow.Register(tk.GetProviderFactoryRegistry()); err != nil {
    log.Fatal(err)
}

// Create provider instance
provider, err := tk.CreateProvider("siliconflow", config)
if err != nil {
    log.Fatal(err)
}

🧪 Testing

🔒 Security

• API Key Protection: Keys handled securely, never logged
• HTTPS Only: All API calls use HTTPS
• Input Validation: Comprehensive validation of all inputs
• Error Sanitization: Sensitive information removed from errors

📈 Performance

• Smart Caching: Model discovery results cached to reduce API calls
• Connection Pooling: HTTP client reuses connections
• Concurrent Safety: Thread-safe implementation
• Memory Optimized: Efficient JSON processing and streaming support

🐛 Troubleshooting

Common Issues

1. API Key Not Found

   export SILICONFLOW_API_KEY=your-key
   

2. Timeout Errors

   • Increase timeout in configuration
   • Check network connectivity

3. Rate Limiting

   • Implement retry logic with backoff
   • Check rate limit configuration

4. Model Not Found

   • Verify model ID is correct
   • Run model discovery to see available models

Debug Mode

Enable detailed logging:

import "log"

log.SetFlags(log.LstdFlags | log.Lshortfile)
// Provider will log detailed information
