Google 推出 A2A 协议：智能体互操作的新时代
Google Introduces A2A Protocol: A New Era of Agent Interoperability
Google 宣布推出 A2A（Agent-to-Agent）协议，这是一个开放协议，为智能体之间的协作提供了标准方式，无论底层框架或供应商如何。这标志着智能体互操作新时代的开始。
A2A 的设计遵循五项关键原则：
- 拥抱智能体能力：A2A 专注于使智能体能够以自然的、非结构化的方式协作，即使它们不共享内存、工具和上下文。
- 基于现有标准构建：该协议建立在 HTTP、SSE、JSON-RPC 等流行的现有标准之上，意味着更容易与企业日常使用的现有 IT 堆栈集成。
- 默认安全：A2A 设计支持企业级身份验证和授权，在发布时即与 OpenAPI 的身份验证方案保持一致。
- 支持长时间运行的任务：A2A 设计灵活，支持从快速任务到可能需要数小时甚至数天的深度研究场景。
- 模态无关：智能体世界不仅限于文本，A2A 支持各种模态，包括音频和视频流。
Google 与 50 多个合作伙伴共同推动这一协议的发展，包括 Atlassian、Box、Cohere、LangChain、MongoDB、Salesforce、ServiceNow 等。

Google announced the A2A (Agent-to-Agent) protocol, an open protocol that provides a standard way for agents to collaborate with each other, regardless of the underlying framework or vendor. This marks the beginning of a new era of agent interoperability.
A2A follows five key design principles:
- Embrace agentic capabilities: A2A focuses on enabling agents to collaborate in their natural, unstructured modalities, even when they don't share memory, tools and context.
- Build on existing standards: The protocol is built on top of existing, popular standards including HTTP, SSE, JSON-RPC, making it easier to integrate with existing IT stacks.
- Secure by default: A2A is designed to support enterprise-grade authentication and authorization, with parity to OpenAPI's authentication schemes at launch.
- Support for long-running tasks: A2A is designed to be flexible and support scenarios from quick tasks to deep research that may take hours or even days.
- Modality agnostic: The agentic world isn't limited to just text, which is why A2A supports various modalities, including audio and video streaming.
Google is working with over 50 partners to advance this protocol, including Atlassian, Box, Cohere, LangChain, MongoDB, Salesforce, ServiceNow, and more.
