public class AnthropicChatModel
extends ChatModelBase

Anthropic Chat Model implementation using the official Anthropic Java SDK.

This implementation provides complete integration with Anthropic's Messages API, including tool calling, streaming support, and extended thinking features.

Important notes:

• System messages are handled via the system parameter, not as messages
• Tool results must be in separate user messages
• Supports Claude models (claude-3-*, claude-sonnet-*, etc.)
