Google Antigravity

Google's agentic IDE and SDK. The IDE uses Google's own model list; the Antigravity SDK can talk to any OpenAI-compatible endpoint.

Step by step

01
Get your key
Redeem a voucher at /redeem and copy the key.
02
Install the SDK
pip install google-antigravity
03
Set the key
Export OPENAI_API_KEY="lxc_live_YOUR_KEY".
04
Run the agent
Use the snippet below; model is any id from the /models page.
Protocol
OpenAI Chat Completions
Configured in
LocalOpenAIAgentConfig
Base URL
https://api.luxechain.si/v1

antigravity
import asyncio
import os

os.environ["OPENAI_API_KEY"] = "lxc_live_YOUR_KEY"   # the SDK's OpenAI client reads this

from google.antigravity import Agent, LocalOpenAIAgentConfig


async def main():
    config = LocalOpenAIAgentConfig(
        model="YOUR_MODEL_ID",                 # any model id from the /models page
        base_url="https://api.luxechain.si/v1",
    )
    async with Agent(config) as agent:
        response = await agent.chat("Hello")
        async for token in response:
            print(token, end="", flush=True)


asyncio.run(main())
The Antigravity IDE cannot be repointed to a custom provider. This guide uses the Antigravity Python SDK, whose LocalOpenAIAgentConfig connects to any OpenAI-compatible base URL. The SDK's OpenAI client takes the key from OPENAI_API_KEY.
