Rabbit releases OS3 agentic operating system without R1

Rabbit Releases OS3 Agentic Operating System

Rabbit Inc. announced the general release of OS3 on September 22, 2026, an agentic operating system running across Windows, Mac, Linux, cloud instances, and its own devices.

The company said OS3 became generally available on September 22, 2026, and does not require the R1 gadget to use. Users can also access OS3 through a desktop browser, Telegram, iMessage, RCS, SMS, or Rabbit's orange R1 handheld device today.

Chief Executive Officer Jesse Lyu said the company spent two and a half years building a system users simply tell the outcome rather than operate themselves.

OS3 runs primarily in the cloud but connects to local devices through a Rabbit agent that installs with one command on Windows, Mac, or Linux machines.

Users can connect up to five devices to one account and choose their preferred AI models for different tasks securely. OS3 fully automatically determines which devices, files, applications, and AI models it needs to complete each request on its own.

Large Action Model Powers Cross-Platform Automation

OS3 relies on Rabbit's Large Action Model for understanding user intent and translating it into actions across various web services. The Direct Large Action Model extends that capability to direct desktop control without developer-built plugins or separate integrations per service.

Rabbit calls these abilities universal skills because they work across platforms without being rebuilt for each operating system, allowing tasks to move seamlessly between different devices.

OS3 can directly click buttons, fill out forms, and navigate local desktop or web interfaces on a user's personal behalf. It can also write, debug, and run software workflows autonomously on local connected devices using the Direct Large Action Model.

Rabbit argues no major platform incumbent will build a truly platform-agnostic agent as Microsoft primarily favors Windows and Apple primarily favors macOS for their own commercial interests.

OS3 offers Bring Your Own Key flexibility, letting users power it with API keys from frontier AI labs or local models. Users can freely swap models without affecting their context, memory, or installed skills in the system, Rabbit said on Tuesday.

R1 Hardware History and Financial Details

Rabbit launched its R1 hardware in January 2024 at a price of $199 as a dedicated AI companion designed to bypass the traditional smartphone app ecosystem entirely.

Chief Executive Officer Jesse Lyu told WIRED the company delivered more than 100,000 orange-red R1 units worldwide since its launch. He said return rates stayed below 5 percent, and Rabbit earned a 45 to 50 percent margin on the hardware.

Rabbit has raised around $60 million in total, employs only 15 people, and Lyu said there are no current issues with the company's overall financial health.

After early poor reviews at launch, the company chose to stay lean and did not expand its team significantly further. A planned India launch was stymied by regulations, causing financial strain and a strike by some employees over unpaid wages.

Rabbit stopped manufacturing R1 devices, later secured more funding, plans a vibe-coding cyberdeck, and publicly launched OS3 without independent public reviews or detailed analyst assessments yet.
