Anthropic (Claude)

Anthropic is the company behind the Claude family of large language models, known for their strong reasoning capabilities, long context windows, and robust tool-calling support.

Setup

To use Claude models with MyCoder, you need an Anthropic API key:

1. Create an account at Anthropic Console
2. Navigate to the API Keys section and create a new API key
3. Set the API key as an environment variable or in your configuration file

Environment Variables

You can set the Anthropic API key as an environment variable:

export ANTHROPIC_API_KEY=your_api_key_here

Configuration

Configure MyCoder to use Anthropic's Claude in your mycoder.config.js file:

export default {
  // Provider selection
  provider: 'anthropic',
  model: 'claude-3-7-sonnet-20250219',
  
  // Optional: Set API key directly (environment variable is preferred)
  // anthropicApiKey: 'your_api_key_here',
  
  // Other MyCoder settings
  maxTokens: 4096,
  temperature: 0.7,
  // ...
};

Supported Models

Anthropic offers several Claude models with different capabilities and price points:

• claude-3-7-sonnet-20250219 (recommended) - Strong reasoning and tool-calling capabilities with 200K context
• claude-3-5-sonnet-20240620 - Balanced performance and cost with 200K context
• claude-3-opus-20240229 - Most capable model with 200K context
• claude-3-haiku-20240307 - Fastest and most cost-effective with 200K context

Best Practices

• Claude models excel at complex reasoning tasks and multi-step planning
• They have strong tool-calling capabilities, making them ideal for MyCoder workflows
• Claude models have a 200K token context window, allowing for large codebases to be processed
• For cost-sensitive applications, consider using Claude Haiku for simpler tasks

Token Caching

MyCoder implements token caching for Anthropic's Claude models to optimize performance and reduce API costs:

• Token caching stores and reuses parts of the conversation history
• The Anthropic provider uses Claude's native cache control mechanisms
• This significantly reduces token usage for repeated or similar queries
• Cache efficiency is automatically optimized based on conversation context

You can enable or disable token caching in your configuration:

export default {
  provider: 'anthropic',
  model: 'claude-3-7-sonnet-20250219',
  tokenCache: true, // Enable token caching (default is true)
};

Troubleshooting

If you encounter issues with Anthropic's Claude:

• Verify your API key is correct and has sufficient quota
• Check that you're using a supported model name
• For tool-calling issues, ensure your functions are properly formatted
• Monitor your token usage to avoid unexpected costs
