Anthropic Provider

Provider for integrating with Anthropic's Claude models. Supports various models like Claude, Claude Instant, etc.

Features

• Support for Claude models (claude-3-opus, claude-3-sonnet, etc.)
• Function calling (Tool Use) support
• Streaming response support
• High-quality reasoning and safety mechanisms

Installation

npm install @robota-sdk/anthropic

Usage

Basic Usage

import { Robota, AnthropicProvider } from 'robota';
import Anthropic from '@anthropic-ai/sdk';

// Create Anthropic client
const anthropicClient = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY
});

// Initialize Anthropic provider
const provider = new AnthropicProvider({
  model: 'claude-3-opus',
  temperature: 0.7,
  client: anthropicClient
});

// Connect provider to Robota instance
const robota = new Robota({ provider });

// Execute
const result = await robota.run('Hello! How is the weather today?');
console.log(result);

Using Function Calling

import { Robota, AnthropicProvider } from 'robota';
import Anthropic from '@anthropic-ai/sdk';

// Create Anthropic client
const anthropicClient = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY
});

// Initialize Anthropic provider
const provider = new AnthropicProvider({
  model: 'claude-3-opus',
  client: anthropicClient
});

// Create Robota instance
const robota = new Robota({ provider });

// Register functions
robota.registerFunctions({
  getWeather: async (location: string) => {
    // Weather lookup logic
    return { temperature: 22, condition: 'Clear', location };
  }
});

// Execute
const result = await robota.run('What is the weather in Seoul?');
console.log(result);

Handling Streaming Responses

import { Robota, AnthropicProvider } from 'robota';
import Anthropic from '@anthropic-ai/sdk';

// Create Anthropic client
const anthropicClient = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY
});

// Initialize Anthropic provider
const provider = new AnthropicProvider({
  model: 'claude-3-opus',
  client: anthropicClient
});

// Create Robota instance
const robota = new Robota({ provider });

// Handle streaming response
const stream = await robota.stream('Tell me a long story.');

for await (const chunk of stream) {
  process.stdout.write(chunk.content || '');
}

Provider Options

Anthropic provider supports the following options:

interface AnthropicProviderOptions extends ProviderOptions {
  // Required options
  model: string;       // Model name to use (e.g., 'claude-3-opus')
  client: Anthropic;   // Anthropic client instance

  // Optional options
  temperature?: number;  // Randomness/creativity of the response (0~1)
  maxTokens?: number;    // Maximum number of tokens to generate
  stopSequences?: string[]; // Stop sequences during generation
  topP?: number;         // Top-p sampling (0~1)
  topK?: number;         // Top-k sampling
}

Model Selection Guide

Model	Features	Recommended Use Cases
claude-3-opus	Highest performance, complex reasoning	High-quality content generation, complex problem solving
claude-3-sonnet	Balanced performance and speed	General conversation, medium complexity tasks
claude-3-haiku	Fast speed, economical	Simple tasks, when high volume is needed

Notes

• Always manage your Anthropic API key through environment variables or a secure secret management system.
• Claude models use a different function calling mechanism (Tool Use) than OpenAI. Robota abstracts these differences, but there may be model-specific limitations for certain features.
• Content safety filtering may be stricter than other models.
