Google Antigravity with Gemini 3: What Google launched in November 2025 and what changed since
Updated: Sep 16
Google launched Antigravity on November 18, 2025 as an agentic development platform built around Gemini 3 and a familiar AI-powered IDE. The original product combined direct access to editor, terminal, and browser tools with a second Agent Manager surface for supervising autonomous work across multiple workspaces.
This page now preserves that launch context rather than presenting late-2025 preview conditions as current product behavior. Current Antigravity access, pricing, and product surfaces have changed materially since launch.

GOOGLE LAUNCHED ANTIGRAVITY ON NOVEMBER 18, 2025
The first Antigravity release was a public preview for macOS, Windows, and Linux. Google positioned it as an agent-first development environment where agents could plan and execute longer software tasks instead of limiting AI assistance to code completion or isolated chat interactions.
At launch, access was available at no charge. Usage limits were work-based and refreshed every five hours, meaning a short task and a long autonomous workflow did not consume capacity in the same way.

Launch dimension | November 2025 state | How to read it today |
Release status | Public preview | Historical launch condition |
Platforms | macOS, Windows, Linux | Desktop availability established at launch |
Core surfaces | Editor + Agent Manager | Predecessor to the later split between IDE and standalone Antigravity |
Tool access | Editor, terminal, browser | Foundation of the current agent runtime |
Access model | No-charge preview with work-based limits | Do not treat as current pricing or quota policy |

THE ORIGINAL PRODUCT COMBINED AN EDITOR AND AN AGENT MANAGER
The 2025 design used two complementary surfaces. Editor View looked like an AI-powered IDE and allowed an agent to inspect files, modify code, run commands, and interact with the browser. Agent Manager acted as a higher-level mission-control surface for spawning, observing, and coordinating agents working across separate workspaces.
That division is important historically because Google later separated these ideas more cleanly: the IDE remained a coding environment, while Antigravity 2.0 became a standalone agent command center.

ARTIFACTS WERE BUILT AS A TRUST LAYER
Antigravity did not rely only on a stream of model messages to explain what an agent had done. The launch product generated Artifacts such as task lists, implementation plans, walkthroughs, screenshots, and browser recordings so that the user could inspect the work product and the execution path.
The design paired greater autonomy with evidence that could be reviewed and corrected. Users could also provide inline feedback on Artifacts, turning review into part of the agent workflow rather than a separate final step.

GEMINI 3 WAS THE LAUNCH FOUNDATION, NOT THE WHOLE PRODUCT
Gemini 3 Pro was the flagship model associated with the November 2025 launch, but Antigravity was not architected as a single-model shell. Google also offered access to Claude Sonnet 4.5 and OpenAI GPT-OSS in the launch environment, subject to capacity.
The model layer has continued to change since then. For SEO and product accuracy, the durable part of Antigravity is the agent platform and its tools, not the assumption that one November 2025 model remains the permanent default.

THE PUBLIC PREVIEW HAD A DIFFERENT ACCESS MODEL
The original preview was deliberately generous to accelerate experimentation. Google's launch documentation described rate limits that refreshed every five hours and were correlated with the amount of work completed by the agent rather than a fixed message count.
Historical fact: the launch access model belongs to November 2025. Current free access, subscriptions, and top-ups are covered separately so this article does not compete with current pricing pages.

WHAT CHANGED AFTER THE 2025 LAUNCH
By Google I/O 2026, Antigravity had expanded from one development product into an ecosystem. Antigravity 2.0 became a standalone desktop application, the IDE continued separately, a CLI arrived for terminal-first work, and Google exposed the same agent through an SDK and API for programmatic use.
The core capabilities also expanded to subagents, hooks, scheduled tasks, richer agent management, and other asynchronous workflows. Later 2026 releases added more model options and additional integrations, further reducing the usefulness of treating the November 2025 configuration as the current product definition.
