Rabbit launches OS3 agentic operating system for multiple platforms

Rabbit Launches OS3 Agentic Operating System

Rabbit announced its new OS3 on September 22, 2026, a standalone agentic operating system that runs across multiple screens and beyond the company's handheld R1 gadget.

The system arrives as a software update for the existing R1 and also as a service usable without R1 hardware. Users can also reach it through a desktop browser, through Telegram on a mobile phone, or directly through Apple's iMessage application.

OS3 also runs on Windows, Mac, and Linux personal computers, on cloud instances, and on Rabbit's own devices, including the r1 and an upcoming cyberdeck product.

The company described OS3 as a chat-based system that abandons the traditional app grid, allowing users to simply describe the outcome and let the software act.

Rabbit said OS3 represents two and a half years of foundational work toward a platform that responds to plain-language commands. Chief Executive Officer Jesse Lyu framed the release as the culmination of years spent building a system users now simply instruct.

CEO Cites R1 Sales Success And Company Recovery

Jesse Lyu, chief executive and founder of Rabbit, said the handheld R1 gadget was tremendously successful from a monetary perspective. He claimed the company delivered more than 100,000 orange-red hardware units worldwide, with overall return rates of less than five percent.

Lyu said Rabbit has raised approximately 60 million dollars in total funding and currently employs just 15 full-time people on its lean software and hardware team.

He attributed internal challenges to being extremely limited in resources compared with other AI studios that raised billions of dollars. The R1 faced scathing reviews after its early January 2024 launch, and a planned India release was stymied by regulatory obstacles.

Around this time last year, Rabbit faced serious financial strain, and a handful of employees went on strike claiming they were not being paid their wages.

In a public statement, Lyu said he respected the striking employees' decision and, after securing additional funding, sees no issues with the company's overall current health.

Cross-Platform Bet Targets Rival Ecosystem Gaps

Under the hood, OS3 relies on two core technologies: the Large Action Model, which translates user intent into sequences of actions, and the Direct Large Action Model.

The Direct Large Action Model extends that capability to direct desktop control, allowing OS3 to click buttons, fill out forms, and navigate software interfaces on a user's behalf.

Rabbit calls these capabilities universal skills, which work across platforms without needing to be rebuilt for every individual operating system. A task that starts on a Mac can be continued on a Windows machine or handed off to a cloud instance.

Rabbit's bet is that no major platform incumbent, such as Microsoft or Apple, will build a truly seamless platform-agnostic agent, leaving a broad gap for a cross-platform layer.

OS3 arrives as a striking pivot for a company that once championed handheld hardware, and it launched without independent reviews. Rabbit has deployed roughly 50 software updates over the past year and a half to polish the R1 experience for users.
