Rabbit’s new OS3 lets AI work across your computer, phone, and chats

Rabbit has launched OS3, a cloud based AI agent system that can connect to software, files, and web pages on users’ Windows, Mac, and Linux computers. Julian Chokkattu reports for WIRED that the system also works through a web browser, Telegram, iMessage, and the company’s Rabbit R1 device.

OS3 marks a shift for Rabbit, which became known for the R1, a dedicated AI device released in 2024. Reviews criticized the gadget’s early ability to carry out tasks in apps. Rabbit founder Jesse Lyu tells WIRED the company is now prioritizing software rather than planning a direct R1 successor.

The platform runs in the cloud but requires users to install a local agent on their computer. That agent can access desktop applications and files to complete tasks requested from another device. Rabbit says one OS3 account can connect up to five machines, with the system selecting the appropriate device for each job.

How Rabbit OS3 works

Users interact with OS3 through one ongoing chat rather than separate conversations. They can ask the agent to perform routine work, such as transferring data from a sales spreadsheet into a master file. Lyu says he has also used the system to have an agent represent him in a Slack discussion. In that case, the agent identified itself to the other participant.

Rabbit uses a bring your own key model. The company does not charge a monthly subscription, but users need API keys from providers such as OpenAI or Anthropic, or must connect a local open source model. OS3 can also install third party agent skills when users paste a public link into the chat, according to Rabbit.

Rabbit says its local software does not copy or sell file contents. However, prompts needed for AI reasoning pass through Rabbit’s servers to the chosen model provider. Conversations and memory logs are stored on Rabbit’s servers.
