Anthropic Module

Overview

The Anthropic module provides integration with Anthropic's Claude language models. This module configures and manages connections to Claude models for AI-powered functionality within the BidScript application.

Configuration

The Anthropic integration is configured in anthropic.config.ts, which includes:

• API key management
• Model configuration (Claude 3.5 Sonnet, Claude 3.7 Sonnet)
• Error handling and logging

Key Components

AnthropicConfigService

The AnthropicConfigService is the main service responsible for:

• Loading and validating Anthropic API credentials
• Providing model-specific configurations
• Managing deployment keys

export type DeploymentKey =
  | ModelType.CLAUDE_3_7_SONNET
  | ModelType.CLAUDE_3_5_SONNET;

@Injectable()
export class AnthropicConfigService {
  private readonly logger = new Logger(AnthropicConfigService.name);
  private readonly anthropicApiConfig: Record<DeploymentKey, AnthropicConfig>;

  constructor(private configService: ConfigService) {
    // Load configuration from environment variables
    const anthropic_key = this.configService.get<string>("ANTHROPIC_API_KEY");

    this.anthropicApiConfig = {
      [ModelType.CLAUDE_3_7_SONNET]: {
        apiKey: anthropic_key || "",
      },
      [ModelType.CLAUDE_3_5_SONNET]: {
        apiKey: anthropic_key || "",
      },
    };
  }

  // Methods to access and validate configurations
}

Integration with Other Modules

The Anthropic module integrates with:

• Chat Module: For generating responses in chat contexts
• RAG Module: For retrieval-augmented generation with Claude models
• LangChain Module: For chaining together LLM operations

Environment Variables

The module requires the following environment variables:

• ANTHROPIC_API_KEY: API key for accessing Anthropic's Claude API

Usage Example

// Example of using the Anthropic module for generating text
import { AnthropicConfigService } from "./anthropic/anthropic.config";
import { ModelType } from "./config/model.config";
import { Anthropic } from "@langchain/anthropic";

// In a service that uses Anthropic
@Injectable()
export class SomeService {
  constructor(private anthropicConfigService: AnthropicConfigService) {}

  async generateText(prompt: string): Promise<string> {
    const config = this.anthropicConfigService.getConfig(
      ModelType.CLAUDE_3_5_SONNET
    );

    const model = new Anthropic({
      apiKey: config.apiKey,
    });

    const response = await model.invoke(prompt);
    return response;
  }
}
