Technical Specifications
| Feature | Google Antigravity | Tabnine |
|---|---|---|
| Core AI Model(s) | Powered by Google's Gemini 3 Pro model as default, with support for Anthropic's Claude Sonnet 4.5 and OpenAI's GPT-OSS for flexible model selection. | Tabnine uses its own proprietary, private AI models for code completion and chat. It also allows users to switch to third-party models from providers like Anthropic (Claude), OpenAI (GPT), Cohere, and Mistral. |
| Context Window | Supports large context windows through Gemini 3 Pro's advanced architecture, with multimodal processing of code, images, and design mocks. | Tabnine is context-aware, analyzing your local IDE environment and project files to provide relevant suggestions. The Enterprise plan allows connecting to an organization's entire codebase (GitHub, GitLab, Bitbucket) for more deeply personalized, context-aware recommendations. |
| Deployment Options | Available as a downloadable desktop application for Windows, macOS, and Linux. Currently in public preview with enterprise features planned. | Tabnine offers flexible deployment. It is available as a secure multi-tenant SaaS for all users. For Enterprise customers, it offers fully private deployments on-premises, in a Virtual Private Cloud (VPC), or in a completely air-gapped environment. |
| Offline Mode | Limited offline capabilities; core agentic features require cloud connectivity for AI model inference and agent orchestration. | Yes, Tabnine's AI can run locally on a developer's machine, on a server behind a firewall, or in the cloud, supporting offline use cases. |

Google Antigravity vs Tabnine: Agentic vs Completion Focus
Google Antigravity and Tabnine represent two different generations of AI coding tools—autonomous agents vs intelligent autocomplete:
Autonomous Agents vs Autocomplete
Google Antigravity deploys AI agents that independently complete multi-step coding tasks. Tabnine focuses on line-by-line code suggestions as you type.
Privacy-First Architecture
Tabnine offers local processing and strict privacy controls, ideal for sensitive codebases. Antigravity processes code through Google's cloud infrastructure.
Scope of Assistance
Antigravity can architect features, refactor systems, and coordinate multiple files autonomously. Tabnine excels at completing the current line or function you're writing.
Personalization Approach
Tabnine learns your personal coding patterns for highly personalized suggestions. Antigravity uses general-purpose frontier models with self-improvement from feedback.
Integration Model
Tabnine integrates as a lightweight extension in your existing IDE. Antigravity is a standalone IDE with its own interface and workflow.
Enterprise Security
Tabnine offers on-premises deployment and SOC 2 compliance for enterprise security requirements. Antigravity is cloud-based with Google's security model.
Choose Google Antigravity for complex agentic workflows, autonomous multi-file development, and when you want AI to handle entire features independently.
The Bottom Line
Google Antigravity and Tabnine each serve different needs. Google Antigravity scores higher (92/100 vs 86/100) and tends to excel in Agentic Workflows and AI-Native Development. The right pick depends on your workflow, team size, and technical constraints.
Choose Google Antigravity if: you prioritize Agentic Workflows and AI-Native Development and want the higher-rated option (92/100 vs 86/100).
Choose Tabnine if: you prioritize Code Completion and Privacy-conscious Development and accept a slightly lower headline score for its specialized fit.
