Introducing Support for Local AI Models in the Antigravity SDK

Today, we’re announcing that the Antigravity SDK supports local workflows across a wide range of local models and execution options, featuring initial support for Gemma 4 26B A4B using Google AI Edge’s LiteRT.

The Antigravity SDK enables developers to build with the same agentic capabilities that power Google Antigravity. With this new support you can enable agentic assistance via local models completely offline. We’ve optimized this workflow for LiteRT and Gemma 4 26B, efficiently using the local GPU and RAM in order to further amplify what your local machine is capable of delivering!

Why run agents locally?

Local model execution offers several advantages for agentic experiences:

Cost efficiency: Execute local agentic workflows without API costs or rate limits.

Privacy: Keep your code and requests entirely on your local machine, ideal for developers navigating strict data privacy requirements or compliance-restricted corporate environments.

Offline resiliency: Execute your agentic workflows seamlessly, even in environments where a consistent or stable internet connection is unavailable.

Hybrid workflows: Combine token-efficient local processes with cloud-based ones to maximize efficiency while retaining access to larger, more powerful models when needed.
