Google announced that the Antigravity SDK now supports local AI model execution, allowing developers to build agentic applications that run entirely offline. The update features initial support for the Gemma 4 26B A4B model using Google AI Edge’s LiteRT runtime. This enables the use of local GPU and RAM resources for agentic tasks, such as code auditing and utility generation, without relying on cloud connectivity. The SDK also includes plug-and-play support for OpenAI-compatible local servers like Ollama, LM Studio, and vLLM.
Google has introduced support for local AI models in the Antigravity SDK, a tool that enables developers to build applications with the same agentic capabilities that power Google Antigravity. This update allows for the execution of agentic workflows completely offline, utilizing local hardware resources such as GPU and RAM.
The initial implementation features support for the Gemma 4 26B A4B model, optimized for Google AI Edge’s LiteRT runtime. Google states that this optimization efficiently leverages local machine capabilities to enhance what can be delivered on-device. The announcement includes a sample Python script, agy_sample.py, to help developers get started with this local workflow.
The SDK also provides seamless support for any OpenAI-compatible server, including Ollama, LM Studio, and vLLM, through a LocalOpenAIAgentConfig. This flexibility allows developers to experiment with different local backends while maintaining consistent agent orchestration, tools, and workflows.
Google demonstrated the utility of this setup through a hybrid demo where a cloud-based architect model (Gemini 3.8 Flash) acted as a planner, while a local swarm of Gemma 4 26B instances handled code auditing and patching tasks. Another example showed the local agent autonomously building a live-updating terminal resource monitor using Python libraries like psutil and rich, all without internet access.

Por qué es importante
This update lowers the barrier for developers to deploy AI agents in environments where data privacy, latency, or internet connectivity are critical constraints. By supporting local execution, the SDK allows for hybrid architectures where cloud models handle high-level planning while local models perform heavy computational lifting on-device. This approach can reduce token costs and ensure sensitive data remains on the user's machine. The specific optimization for LiteRT and Gemma 4 26B provides a concrete, tested pathway for edge AI development, moving beyond theoretical local AI concepts to practical, integrated tooling within a major tech company's developer ecosystem.
The ability to run agentic AI locally addresses significant concerns regarding data privacy and security, as sensitive code and data do not need to be transmitted to external cloud servers. This is particularly relevant for enterprise environments or individual developers working with proprietary or confidential information.
By supporting a hybrid Architect-Builder pattern, the SDK offers a practical solution for balancing the scale of cloud models with the privacy and cost-efficiency of local models. This architecture allows for complex planning tasks to be handled by powerful cloud models while routine or heavy-lifting tasks are executed locally, optimizing token utilization and reducing latency.
The specific recommendation for hardware with over 24GB of VRAM or unified memory sets a clear technical baseline for users. While this limits immediate accessibility to high-end machines, it provides a concrete target for developers and hardware manufacturers aiming to support advanced local AI workloads.
The integration of LiteRT and support for standard local servers like Ollama and vLLM reduces the friction for developers already familiar with these tools. This standardization helps consolidate the fragmented landscape of local AI development, offering a unified interface for agent orchestration regardless of the underlying local model backend.

Developers should monitor the Antigravity Python SDK GitHub repository for updates to the local model configuration and performance benchmarks. The practical viability of the recommended hardware requirements, specifically machines with over 24GB of VRAM or unified memory, will determine the accessibility of these features for a broader developer base. Additionally, the adoption of the Architect-Builder pattern, which combines cloud planning with local execution, may influence how hybrid AI systems are designed in enterprise and consumer applications.
The performance and stability of the Gemma 4 26B A4B model when running on consumer-grade hardware with the recommended 24GB+ VRAM will be a key indicator of the 's practical utility. Early adopters may report on latency, memory management, and the quality of agentic outputs in real-world scenarios.
The evolution of the Antigravity SDK's support for other local models and backends will determine its long-term relevance. If Google expands support to smaller or more efficient models, the hardware requirements may decrease, broadening the potential user base.
The adoption of the hybrid cloud-local workflow in enterprise settings will be a significant trend to monitor. If this pattern proves effective for maintaining data privacy while leveraging cloud intelligence, it could become a standard architecture for AI-driven development tools.
Community feedback on the Antigravity Python SDK GitHub Issue Tracker will provide insights into common challenges and requests. This feedback loop is crucial for understanding the real-world limitations of the current implementation and guiding future updates.
