Rabbit has launched Rabbit OS3, a cloud-based AI agent app that can operate Windows, Mac and Linux computers without requiring a Rabbit R1. The service is available through a desktop or mobile browser, Telegram, iMessage/RCS/SMS or Rabbit’s orange handheld, giving the company a software-first answer to the hardware-first pitch that made the R1 famous for reasons both good and otherwise.
Rabbit says OS3 connects up to five devices to one account and decides where a task should run. A user can ask it to work across a local computer, cloud virtual machine or dedicated AI machine, with the system moving files, applications and skills between those environments when needed. The local Rabbit agent installs with a single command.
Rabbit OS3 moves beyond the R1
The company announced the general release on 22 September, describing OS3 as an agentic operating system built around one continuous chat rather than separate sessions. Rabbit says the service can remember earlier instructions and operate connected devices in the background.
The bigger change is that the R1 is now one endpoint among several. WIRED’s report says Rabbit has delivered more than 100,000 R1 units, despite the device receiving a 3/10 review from the outlet at launch. Rabbit founder Jesse Lyu told WIRED the company has raised around $60 million and employs 15 people.
Rabbit is also making the service deliberately open. Users can bring API keys from major AI labs, cloud routers or locally hosted models, then swap models without changing their context, memory or installed skills. Skills can be installed by pasting a public URL into the chat, while the local agent can control desktop software, files and web pages and run coding workflows.
What Rabbit’s AI agent can actually use
Rabbit’s official announcement via PR Newswire says OS3 is available now and will also ship as the default operating system on the company’s upcoming Cyberdeck. The announcement does not list a subscription price, and it does not confirm UAE-specific availability.
The move puts Rabbit into a busier category that already includes products such as OpenClaw’s shared browser sessions and ChatGPT Agent. Rabbit’s difference is the attempt to keep one agent identity across local computers, cloud machines and messaging apps. Whether that is useful depends on how reliably it handles the boring parts: permissions, logins and tasks that stop being clever once a website changes its layout.
Do you need a Rabbit R1 to use Rabbit OS3?
No. Rabbit says OS3 can be accessed through a desktop or mobile browser, Telegram and iMessage/RCS/SMS. The R1 is one supported endpoint, not a requirement.
Which computers can Rabbit OS3 control?
Rabbit says the local agent can connect Windows, Mac and Linux PCs, cloud virtual machines and dedicated AI machines. It can operate desktop software, files and web pages.
Can you use your own AI model with Rabbit OS3?
Yes. Rabbit says users can bring API keys from frontier AI labs, cloud router platforms or locally hosted models, then change models without losing context, memory or skills.
