Rabbit, the startup that released the R1 device, has announced a new AI agent. The agent runs in the cloud but works locally on Windows, Mac, and Linux. It does not require Rabbit’s R1 hardware.
The new system, called OS3, is an agentic operating system. It is designed to give users a virtual assistant that can run on any computer. The company says the agent can be accessed through a lightweight client, making it easier to use than the R1’s bulky hardware. The move follows criticism of the R1, which many reviewers found underwhelming.
OS3 uses a lightweight client that communicates with Rabbit’s servers. The client handles voice input, displays results, and stores local data. All heavy processing, such as natural‑language understanding and generation, happens in the cloud. This architecture eliminates the need for a custom R1 device. Users can simply install the client on any Windows, macOS, or Linux machine.
The company’s decision signals a shift toward software‑first products. By removing the hardware barrier, Rabbit can reach a broader audience. It also reduces manufacturing costs and supply‑chain complexity. The new agent could compete with established AI assistants by offering a more flexible, cross‑platform experience. Early adopters will test the system’s performance and integration with existing workflows.
Rabbit’s launch may reshape the AI assistant market. If the agent proves reliable, it could replace the need for specialized hardware. The company will likely focus on improving the cloud service, adding new features, and expanding platform support. The success of OS3 will determine whether Rabbit can recover from the R1’s lukewarm reception.
Does OS3 require an internet connection? Yes. The agent relies on cloud servers for processing, so a stable internet connection is necessary.
Will my data stay private? Rabbit states that local data is stored on the user’s machine, while only anonymized information is sent to the cloud.
Can I use OS3 on older computers? Yes. The lightweight client works on older Windows, macOS, and Linux systems, as long as they meet minimal hardware requirements.
