What's New?

🔥 Anthropic Integration

Introducing the new langchain_anthropic package, which provides support for the ChatAnthropic chat model wrapper to consume the Anthropic's Messages API. This integration gives you access to cutting-edge models such as Claude 3.5 Sonnet, which sets new standards in reasoning, knowledge and coding, while offering enhanced capabilities in image understanding, data analysis and writing.

final chatModel = ChatAnthropic(
  apiKey: 'yourApiKey',
  defaultOptions: ChatAnthropicOptions(
    model: 'claude-3-5-sonnet-20240620',
  ),
);

ChatAnthropic supports streaming and tool calling. For more information, check out the docs.

  • TavilySearchResultsTool: returns a list of real-time, accurate, and factual search results for a query.
