Antigravity (Interactions)

Run the Antigravity managed agent through the Gemini Interactions API. Antigravity is a general-purpose autonomous agent (Gemini 3.5 Flash) that plans, runs code, browses the web, and produces artifacts (PDFs, HTML, slides) inside a managed Linux sandbox.

The environment parameter selects the sandbox:

Value	Behavior
`"remote"`	Fresh remote Linux sandbox.
`"env_<id>"`	Reuse a previously provisioned sandbox.
`dict`	Full `EnvironmentConfig` (sources, network rules).

Unlike Deep Research, Antigravity runs in the foreground. The model still forces store=True so the interaction is retrievable.

Code

1from kern.agent import Agent
2from kern.models.google import GeminiInteractions

4agent = Agent(
5    model=GeminiInteractions(
6        agent="antigravity-preview-05-2026",
7        environment="remote",
8    ),
