Google Antigravity SDK Adds Local AI Model Support with Gemma 4

On September 24, Google announced via its developer blog and official channels including DynamicWebPaige that the Antigravity SDK (v0.1.18) now supports local AI models, letting developers run open models on-device instead of relying entirely on the cloud — addressing offline development, privacy-sensitive scenarios, and cost control.

Confirmed

Antigravity SDK v0.1.18 adds local model execution: private agent workflows can run fully offline, with cloud-local hybrid orchestration supported.
First supported model is Gemma 4 26B A4B, built on and optimized for Google AI Edge's LiteRT runtime, running directly on local GPUs without network access.
Key selling points: zero API/token cost, full data privacy, no internet required.
Per prajdabre, developers can build fully local or hybrid multi-agent workflows combining cloud frontier models with local Gemma 4 for code auditing, patching and testing, keeping all data on-device; CurieuxExplorer noted Gemma 4 can act as an on-device workforce.
sachinmaya1980 confirmed Gemma 4 is live in the Antigravity SDK for direct testing.

Why it matters

Local agent execution lowers the barrier for budget-constrained, network-restricted, or compliance-sensitive developers.
Hybrid orchestration lets teams use cloud models for performance-critical steps and local Gemma 4 for routine ones, balancing cost and quality.
The LiteRT + Gemma 4 pairing strengthens Google's edge deployment story for its open models.
