   Google adds local model support to Antigravity SDK

   Google added local model support to its Antigravity SDK, letting developers run agent workflows on-device while still calling cloud models for high-level planning. In a demo auditing three Python modules for vulnerabilities, only about 95 of roughly 3,400 tokens were used for cloud planning and no source code left the machine. The SDK also works with local inference servers such as Ollama, LM Studio and vLLM.
