Rabbit launched OS3 on 22 September 2026 as a standalone AI agent for Windows, Mac and Linux that does not require its R1 device, The Verge reported. Rabbit calls it an “agentic operating system”: the company says it runs in the cloud, operates locally on connected computers and chooses the devices, files, apps and AI models it needs for a task.
Key points
- OS3 can be used on Windows, Mac and Linux without buying Rabbit hardware.
- Rabbit says one account can connect up to five devices and use preferred AI models.
- Rabbit has stopped manufacturing the R1 and is focusing on a new OS3 cyberdeck.
- Rabbit says it will retain OS3 chats and associated memories on its servers.
OS3 reaches Windows, Mac and Linux
The shift places Rabbit’s agent on computers people already have rather than making the R1 a condition of using it. Two years earlier, Rabbit had tried to sidestep mobile apps with dedicated AI hardware, Wired reported on 22 September. OS3 is also accessible through the R1, so the new route to the software sits alongside the existing device rather than replacing its means of access.
Rabbit says OS3 lives in the cloud while performing operations locally across Windows, Mac and Linux devices. That distinction matters for an agent intended to work with files and apps: Rabbit describes a system that can draw on connected computers to carry out a task, while its account of OS3 places the system itself in the cloud. The company also says people can reach it through a dedicated desktop site or paired messaging apps such as Telegram and iMessage.
The desktop site, messaging apps and R1 offer different ways to reach the same agent. For a company building a service around OS3, the consequential change is the removal of the hardware purchase from that starting point. The company’s account of the system still depends on computers being connected to an OS3 account for it to select among their files and apps.
Five devices on one OS3 account
Rabbit says an OS3 account can include up to five devices and a person’s preferred AI models. It says the agent then determines which connected devices, files, apps and models a task calls for. The idea is closer to a switchboard choosing where to send a call than to a single assistant confined to one screen: OS3 is meant to make those selections as part of carrying out the request.
Finding a file for a task could, if OS3 works as Rabbit describes, involve the system choosing among connected devices and files rather than requiring that choice at the outset. The proposed convenience rests on the agent identifying the right material and selecting the appropriate model and app for the work.
That selection is the central technical promise in Rabbit’s description of OS3. A person can specify preferred AI models, but Rabbit says the system decides which model a particular task needs, along with the relevant files, apps and devices. For services built on the agent, this would put those choices inside OS3 rather than requiring each request to name every component in advance.
Rabbit stops making the R1
Rabbit founder Jesse Lyu told Wired that the company has stopped manufacturing R1 devices, according to The Verge. The change concerns production of the original hardware, while OS3 remains accessible through R1 devices. Rabbit is instead concentrating its hardware work on a “cyberdeck” for vibe-coding that is intended to run OS3.
The R1 had drawn criticism for bugs and limited functionality, SecNews reported. OS3 changes how Rabbit can distribute its agent, because its Windows, Mac and Linux access no longer depends on ownership of that device. The company is pursuing software that can be used without Rabbit hardware while developing a different piece of hardware for the same system.
OS3 keeps chats on Rabbit servers
Rabbit says OS3 will not store, copy, use or sell user data. It also says chats and memories derived from them will be kept on its servers. Those two parts of Rabbit’s account matter together for anyone deciding what to put into a task: an exchange with the agent can leave a stored conversation and associated memories even under the company’s stated data policy.
OS3 can also use AI models selected for an account, while Rabbit says the agent will choose among models when completing a task. Data handled by other AI providers connected to OS3 will be subject to those providers’ own privacy rules.
