Claude 工具调用功能正式全面可用

Anthropic 于 2024 年 5 月 30 日宣布，Claude 的工具调用功能正式全面可用，覆盖 Claude 3 全模型家族，并支持 Anthropic Messages API、Amazon Bedrock 和 Google Cloud Vertex AI。通过该功能，Claude 可连接外部工具与 API，执行任务、操作数据并提升回答准确性。典型场景包括从发票中提取结构化数据、将自然语言请求转为 API 调用、检索数据库回答问题以及自动化数据录入等。Anthropic 同时改善了开发者体验。

推荐理由：工具调用是构建 Data Agent 的关键基础能力，让 Claude 能直接连接数据库和 API 执行数据操作，数据从业者应关注其对 ChatBI 与分析 Agent 的推动。

Tool use, which enables Claude to interact with external tools and APIs, is now generally available across the entire Claude 3 model family on the Anthropic Messages API, Amazon Bedrock, and Google Cloud's Vertex AI. With tool use, Claude can perform tasks, manipulate data, and provide more dynamic—and accurate—responses.

Tool use

Define a toolset for Claude and specify your request in natural language. Claude will then select the appropriate tool to fulfill the task and, when appropriate, execute the corresponding action:

Extract structured data from unstructured text: Pull names, dates, and amounts from invoices to reduce manual data entry.
Convert natural language requests into structured API calls: Enable teams to self-serve common actions (e.g., "cancel subscription") with simple commands.
Answer questions by searching databases or using web APIs: Provide instant, accurate responses to customer inquiries in support chatbots.
Automate simple tasks through software APIs: Save time and minimize errors in data entry or file management.
Orchestrate multiple fast Claude subagents for granular tasks: Automatically find the optimal meeting time based on attendee availability.

Improved developer experience

To make it easier to leverage the intelligence of the Claude 3 models with tools, we’ve also built in features that help developers further customize the end-user experience.

Tool use with streaming reduces wait times to create more engaging interactions: Streaming enables real-time responses in applications like customer support chatbots for smoother, more natural conversations.
Forced tool use allows developers to instruct Claude on tool selection: Developers can specify which tools Claude should use or leave the choice with Claude, helping create more targeted and efficient applications.
Tools also work with images: Claude can incorporate image inputs in live applications.

During our beta many developers used Opus to build sophisticated user-facing assistants. To further enhance this experience, Opus will now include <thinking> tags in its outputs, clarifying Claude’s reasoning and simplifying the debugging process for developers. Our Claude 3 models are currently unable to support parallel tool calls.
