Anthropic

The @gensx/anthropic package provides a pre-wrapped version of the Anthropic SDK for GenSX, making it easy to use Anthropic’s API with GenSX functionality.

Installation

To install the package, run the following command:


npm install @gensx/anthropic @anthropic-ai/sdk

Usage

You can use this package in two ways:

1. Drop-in Replacement (Recommended)

Simply replace your Anthropic import with the GenSX version:


// Instead of:
// import { Anthropic } from '@anthropic-ai/sdk';
 
// Use:
import { Anthropic } from "@gensx/anthropic";
 
// Create a client as usual
const client = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
});
 
// All methods are automatically wrapped with GenSX functionality
const completion = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
});
 
// Use streaming
const stream = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
  stream: true,
});

2. Wrap an Existing Instance

If you already have an Anthropic instance, you can wrap it with GenSX functionality:


import { Anthropic } from "@anthropic-ai/sdk";
import { wrapAnthropic } from "@gensx/anthropic";
 
// Create your Anthropic instance as usual
const client = wrapAnthropic(
  new Anthropic({
    apiKey: process.env.ANTHROPIC_API_KEY,
  }),
);
 
// Now all methods are wrapped with GenSX functionality
const completion = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
});
