Google has taken the IDE off Antigravity. What is left, announced at I/O 2026, is a standalone desktop app built around agents rather than a code editor with AI bolted on.It is the company's most direct response yet to Claude Code and OpenAI Codex, the two tools that have built strong followings among developers over the past year.
Antigravity 2.0 is out today on macOS, Linux, and Windows, running on a new model called Gemini 3.5 Flash.
The headline number Google is leaning on: 289 output tokens per second on Artificial Analysis, against 67 for Claude Opus 4.7 and 71 for GPT-5.5. Speed is the easy pitch. The more useful claim is that 3.5 Flash also beats Google's own Gemini 3.1 Pro on coding and agentic benchmarks.
What is new inside Antigravity 2.0’s agent layer
The main agent can now spin off subagents it defines on the fly, run them in parallel, and keep its own context window from getting cluttered.
Tasks run asynchronously, so the agent does not stall while something compiles in the background. JSON hooks let you intercept and shape agent behaviour without writing wrappers. A new Scheduled Tasks layer adds cron, so agents can fire on a timer instead of waiting to be invoked.To make the pitch concrete on stage, Antigravity head Varun Mohan said the team had the agents build an operating system from scratch for under $1,000 in tokens—then coded a Doom clone to run on top of it.
The new slash commands say a lot about how Google wants this used. /goal runs to completion without checking in. /grill-me makes the agent ask clarifying questions before it touches a file. /browser is an explicit on-switch, because Google concedes its agents still cannot reliably decide when to open a webpage on their own. Voice input transcribes live instead of shipping audio to the model. Agents are also no longer tied to a single repo—conversations now live inside "projects" that span folders and carry their own permissions.
Antigravity 2.0 brings a new CLI, an SDK, and a rejigged price list
Around the app, Google is pushing a wider Antigravity stack. A new Antigravity CLI replaces the Gemini CLI outright, so existing terminal workflows will need migrating. An SDK lets developers build custom agents on top, and there are deeper hooks into AI Studio, Firebase, and Android, plus a dedicated AI Studio Android app.Pricing got redrawn around the middle. A new $100 AI Ultra tier slots between the $20 Pro plan and the top one, with 5x the Antigravity limits of Pro. The flagship Ultra drops from $250 to $200 with 20x Pro limits. New and existing Ultra subscribers get $100 in bonus credits through May 25.Existing Antigravity IDE users will roll over to 2.0 on their next update.
