// como funciona

Como funciona

  1. Clarify your goal

    Decide the first concrete outcome you want from it, so you can pick the right example, template or mode instead of exploring everything at once.

  2. Get the project

    Clone the repository (or install the published package) and skim its README quick start for the requirements for your platform.

  3. Install and configure

    Run the documented install step and set any required configuration — such as provider keys, data sources or local services — before the first run.

  4. Run your first task

    Execute the smallest documented example end to end, confirm the output is what you expected, then adapt it to your real data or workflow.

Por que as pessoas gostam tanto

One-class agents

The Agent class handles lifecycle, tool wiring, hook registration and policy defaults behind an async context manager.

Streaming everywhere

Stream responses, reasoning/thinking deltas and strongly-typed ToolCall events without blocking.

Custom tools and MCP

Define custom tools and connect MCP servers to extend what agents can do.

Multimodal ingestion

Send mixed text and content objects — filesystem paths resolve automatically to document types.

Hooks, policies and triggers

Control agent behaviour with hooks and policies, and react to triggers.

Local models too

Run agents against locally imported LiteRT-LM models by pointing at the model path.

Execute você mesmo

  1. Clone the repository

    Get the source so you can inspect, configure and run it locally.

    git clone https://github.com/google-antigravity/antigravity-sdk-python.git
    cd antigravity-sdk-python
  2. Install the SDK

    Install the package from PyPI.

    pip install google-antigravity
  3. Set your key and run the quickstart

    Export a Gemini API key for express mode (or use ADC project/location for Vertex standard mode), then run the quickstart Agent example.

    export GEMINI_API_KEY=your-key  # see README quickstart for the agent code

Perguntas frequentes

Who maintains antigravity-sdk-python?

It is maintained by google-antigravity on GitHub (google-antigravity/antigravity-sdk-python), where the source, issues and releases live.

Is it free to use?

Yes — it is free and open source under Apache-2.0, which permits use, modification and commercial redistribution, with licence/notice retention.

Does it need a paid API key?

Express mode uses a Gemini API key (usage is billed by Google); standard mode routes through a Google Cloud project with ADC, and local LiteRT-LM models avoid API calls.

How does it compare to Google's genai SDK used directly, or frameworks like LangGraph?

Compared with Google's genai SDK used directly, or frameworks like LangGraph, antigravity-sdk-python's distinguishing focus is: google's Python SDK for building AI agents on the Antigravity platform and Gemini models. Pick it when that focus matches your need; the alternative may suit you better if its broader or different scope is the priority.

How do I get started?

Clone https://github.com/google-antigravity/antigravity-sdk-python (or install its published package), follow the README quick start to install and configure it, then run the smallest documented example — the Run section on this page mirrors those steps.
