- Add custom parameters directly in the settings UI
- No need to modify code or configuration files
- All changes take effect immediately

### 📋 **Flexible Parameter Management**

- Add custom parameters for any AI provider
- Support for different parameter types:
  - **String**: API keys, model names, custom instructions
  - **Float/Integer**: Temperature, max tokens, top-k values
  - **Boolean**: Enable/disable features like thinking mode
  - **Array**: JSON arrays for list-based configurations

### ⚡ **Real-Time Validation**

- Live parameter validation as you type
- Clear error messages with helpful suggestions
- Color-coded status indicators (green = valid, red = error, yellow = warning)

### 🌍 **Full Internationalization Support**

- Complete Chinese (简体中文) and English UI support
- Localized dialog descriptions and parameter labels
- Automatic language detection based on system settings
- Consistent terminology across all custom parameter interfaces

### 🎯 **Intelligent Parameter Organization**

- **Headers Tab**: HTTP headers (authentication, API versions)
- **Body Tab**: Request parameters (model behavior, limits)

## 🎁 **What This Means for You**

### **Content Creators**

- Fine-tune AI translation quality for your specific content
- Optimize speed vs accuracy based on your workflow
- Save different configurations for different content types

### **Advanced Users**

- Full control over AI model behavior
- Access to provider-specific features
- Custom configurations for specialized use cases

### **Teams & Organizations**

- Share parameter configurations across team members
- Standardize AI settings for consistent results
- Export/import configurations for backup and sharing

## 🔄 **Seamless Migration**

**Nothing changes for existing users!** All your current provider settings continue to work exactly as before. The new custom parameter system is completely optional and backward-compatible.

**Language Support**: The interface automatically adapts to your system language (Chinese/English) with no additional configuration needed.

## 📖 **Quick Start Guide**

1. **Open Settings** → Navigate to your AI provider configuration
2. **Find Custom Parameters** → Look for the new "Custom Parameters" section
3. **Add Parameters** → Use the interface to add custom headers or body parameters
4. **Configure Values** → Set parameter values using appropriate input types
5. **Save & Test** → Changed configuration will be auto saved
6. **Test Translation** → Added more detailed info feedback when click the botton

## 🎯 **Popular Use Cases**

### **Disable Thinking Mode for Faster Processing**

- Add parameter: `thinking = disabled` in body parameters
- Result: 30-50% faster translations with `doubao-seed-1-6-250615` models

### **Custom API Headers**

- Add custom headers like `anthropic-version` for Claude API
- Result: Access to specific API versions and features

### **Temperature Control**

- Add parameter: `temperature = 0.5` for more consistent translations
- Result: More predictable and consistent translation results

### **Token Limit Optimization**

- Add parameter: `max_tokens = 1000` to control response length
- Result: Better cost control and faster responses

## 🛡️ **Safety & Security**

- **Parameter Validation**: Prevents invalid configurations that could break translations
- **Secure Storage**: API keys and sensitive data remain encrypted
- **Graceful Fallbacks**: Invalid parameters won't crash the application
- **Export Safety**: Sensitive information automatically filtered when sharing configurations

## 💡 **Pro Tips**

- **Start Simple**: Begin with basic parameters like temperature or max_tokens
- **Test with Small Files**: Try new parameter configurations on small files first
- **Export Your Settings**: Back up your parameter configurations
- **Use the Help System**: Check parameter documentation for detailed explanations and examples
