AnthropicChatModel
public class AnthropicChatModel extends ChatModelBaseio/agentscope/extensions/model/anthropic/AnthropicChatModel.java:63–460Anthropic 聊天模型，与模型服务通信并返回生成或向量化结果。位于 io.agentscope.extensions.model.anthropic 包，继承自 ChatModelBase。核心成员包括 doStream、getModelName、builder、AnthropicChatModel。
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.)
