Rabbit launches OS3, a cloud agentic operating system that drives up to five user devices

Rabbit released OS3, a cloud-based agentic OS whose one-command local agent controls Windows, Mac, and Linux machines — up to five per account — while task content and prompts are processed on Rabbit's servers.

Rabbit announced OS3, an 'agentic operating system' that runs in Rabbit's cloud but controls users' machines through a local agent installed with a single command (The Verge, 2026-09-22; Help Net Security, 2026-09-23). One account can link up to five devices, including Windows, Mac, and Linux PCs, cloud VMs, dedicated AI computers, and the R1, with the agent able to operate desktop software, local files, web pages, and code to complete a stated goal. OS3 is reachable via a desktop site, Telegram, iMessage, or the R1, and is live at os3.rabbit.tech. Users choose their own AI models, supply their own API keys, can switch models without losing memory or skills, and can add skills by pasting a URL. On privacy, the reports are framed differently but compatible: Rabbit says files stay on the device and that it does not retain data forwarded to the user-chosen model provider, yet chats, derived memories, task content, and prompts are processed on Rabbit's servers. Sensitive actions supposedly require user confirmation, but Rabbit did not define which actions qualify. Separately, Rabbit has discontinued manufacturing the R1 and plans a 'vibe-coding' cyberdeck running OS3 within months. The two outlets do not materially disagree on any fact.

• Rabbit released OS3, an agentic operating system hosted in Rabbit's cloud, live at os3.rabbit.tech (The Verge, 2026-09-22; Help Net Security, 2026-09-23).
• A local agent, installed with one command, carries out tasks on the user's machines.
• One account can link up to five devices, including Windows, Mac, and Linux PCs, cloud VMs, dedicated AI computers, and the R1.
• The agent can operate desktop software, local files, web pages, and code to complete a stated goal, choosing devices, files, apps, and models for a task.
• Access is via a desktop site, Telegram, iMessage, or the R1.
• Users supply their own API keys, choose their AI model provider, and can switch models without losing memory or skills.
• Skills can be added by pasting a URL.
• Rabbit says files stay on the device, but task content and prompts are processed on Rabbit's servers and forwarded to the user-chosen model provider, which Rabbit says it does not retain; chats and memories remain on Rabbit's servers.
