Google Antigravity Python SDK (github.com)

Google has launched the Antigravity Python SDK, designed for developing AI agents utilizing the powerful Antigravity and Gemini frameworks. This SDK includes a secure, scalable, and stateful infrastructure that simplifies the creation of AI agents by abstracting complex processes and allowing developers to focus on agent functionality. Users can start by installing the SDK via PyPI and employing the provided examples, such as a simple "Hello, World!" application, to get acquainted with its operation. The significance of this SDK lies in its comprehensive support for asynchronous programming and real-time interaction, enabling conversational agents to deliver outputs as they are generated, which can enhance user experience in applications. Key features include the ability to attach multimedia files to prompts, register Python functions as callable tools, and implement a policy-based system to control agent behavior. The SDK adopts a three-layer architecture, maintaining a clear separation of concerns between agent functionality, session management, and backend abstraction. This structure not only streamlines development but also integrates seamlessly with external tools and services.
