Rabbit OS3 Goes Standalone, No R1 Required
Rabbit released OS3 on September 22, 2026 as a standalone system that works without its R1 hardware. The launch positions Rabbit as a software platform vendor rather than a single-device company. The Verge
OS3 is an agentic operating system, meaning software designed to carry out multi-step tasks on its own. It runs in the cloud but operates locally across Windows, Mac and Linux devices. One account can link up to five devices along with the user's preferred AI models. For each request, OS3 decides which devices, files, apps and models are needed to finish the task and then coordinates the work across them. The local machines are the working surface. The cloud service acts as the coordinator.
Access is not tied to one app. OS3 is available through a dedicated desktop site, through paired messaging apps including Telegram and iMessage, and through the existing R1 device. Rabbit describes the web workspace as the full surface of OS3. Users connect their computers so OS3 can work with the files and tools already there, rather than uploading work into a separate sandbox. Rabbit
The model policy is the most specific part. OS3 supports bring-your-own-model choice, which means users pick which AI engine handles a task from the supported list. Rabbit's OS3 page lists Claude variants including claude-opus-5, claude-sonnet-5, claude-fable-5 and claude-haiku-4-5 versions, GPT variants including gpt-6-astra, gpt-5.6 series and gpt-5.4 series, plus OpenRouter, Ollama, Z.ai, local models and custom endpoints. A custom endpoint is a user-supplied address where a model runs. Rabbit says OS3 provides one conversational place for working with supported models, skills and connected computers, with memory. Users describe what they want to understand, make or finish, and OS3 brings together the models and skills to handle the steps.
The hardware change is direct. Founder Jesse Lyu says the company has stopped manufacturing R1 devices. Existing R1 stock is dwindling as the company focuses on the OS3 platform, according to concurrent reporting. WIRED Rabbit is developing a new vibe-coding focused device described as a cyberdeck, where vibe-coding means describing software in plain language while AI writes the code. It will run OS3 and is expected to launch within months. That device is a plan, not a shipped product.
On data handling, Rabbit says OS3 will not store, copy, use, or sell user data, but will retain chats and resulting memories on its servers. Short-lived task files and long-term memory are treated differently. Chats and the memories derived from them remain server-side. That storage is what allows continuity and personalization across the five connected machines.
Rabbit's own wording is plain. Its site describes OS3 as "say what you want to make, find or finish" and states that OS3 works through the steps so users do not have to work through them all themselves.
The broader context here is familiar to readers who have followed assistant platforms over the years. Dedicated AI hardware drew attention, but steady use stayed with the computers and messaging tools people already operated. By separating OS3 from R1, adding coordination across several machines, and letting users select models and endpoints including local models, Rabbit is trading device lock-in for a closer fit with existing work. In my view, that is the pragmatic bet. The open questions are practical, not theoretical, and center on permissions, clear records of actions, reliable file handling, and how memory is scoped and revoked. If OS3 can make model choice, skill use and local actions easy to check without adding friction, small teams and individual power users will gain a steady operator that follows them from desktop to phone chat without rebuilding context each time.
