Gemini 4 Argon was introduced in Google Antigravity, featuring a 1-million-token context window, tunable reasoning, and native sub-agent orchestration. The update upleveled the Teamwork multi-agent framework, enabling specialized sub-agents to handle deep systems tasks like C++ RDMA networking and custom TPU kernel development. Google's Graph Mining and Graph Learning teams used it to compress months of low-level engineering work into hours.

Antigravity custom agents can now be packaged and distributed directly inside official Google plugins available through the Build with Google ecosystem. Three Google-partnered plugins (Flutter Accessibility, Firebase Security Rules, and Android Play Release Auditor) have already shipped with native custom agent support, enabling specialized, domain-aware AI agents to run within developer workflows. This marks a platform-level expansion of where and how Antigravity custom agents can be deployed and discovered.

Gemini 3.8 Flash is now available inside Google Antigravity, marking the third Flash release in six weeks. It delivers improvements across agentic development workflows at the familiar speed and cost of Flash, with gains over 3.7 Flash often approaching higher-cost frontier models. Developers can adjust thinking levels to control reasoning depth and latency per task.

Antigravity announced updates to Teamwork, a multi-agent orchestration framework that organizes agents into teams that actively challenge each other's work, look for flaws, and combine the strongest pieces into working solutions autonomously over hours or days. Teamwork ships specialized patterns selected automatically based on task type, including distributed coding, long proof, and others. It is available as /teamwork-preview in Antigravity on all paid plans, powered by Gemini 3.7 Flash.

Antigravity agents can now create, render, and iterate on rich visual components, dynamic dashboards, interactive artifacts, and design mockups in real time directly within the agent interface. This Generative UI capability allows agents to produce interactive HTML/CSS/JS components, live charts, and diagrams without requiring users to switch between screens. The feature reduces context-switching by delivering visual representations of data — such as dependency graphs, simulations, and dashboards — inline in the agent manager.

Antigravity 2.0 introduced Git Version Control System (VCS) Controls directly in the right-side panel, providing a first-class UI for version control operations. The agent sidebar was updated to show all working directory changes (not just agent edits), including changes from Python scripts, separate text editors, and Bash scripts. An embedded terminal tab was also added, allowing users to run tests, linters, build tools, and other command-line utilities without leaving the application.

Antigravity launched lightweight IDE extensions for Visual Studio Code, Visual Studio, Zed, JetBrains, and Xcode. The extensions provide access to conversations, customizations, and multi-agent orchestration that shares context with the rest of the Antigravity ecosystem. Enterprise support for JetBrains and Zed is currently in Preview.

Google Antigravity introduced Gemini 3.7 Flash as its most intelligent workhorse model yet for coding and agents. The model delivers improved performance across coding, knowledge work, and web development with advanced reasoning and better multi-step planning and tool calls. It shows strong gains over 3.6 Flash in first-pass code accuracy, production-ready code generation (DeepSWE v1.1: 65.3% vs 49.0%), and web development (1588 Elo on WebDev Arena).

Google Antigravity has been updated to use Gemini 3.6 Flash as its underlying model. This is the most recent update announced on July 21, 2026, following the previous Gemini 3.5 Flash integration from May 2026.
