rabbit Ships OS3, an Agentic Operating System That Runs Across Up to Five Devices at Once

rabbit has released OS3, which it describes as an agentic operating system built around a single chat interface as its primary entry point. In an announcement on its own newsroom, the Santa Monica, California company says the shift changes how people work with their devices: a user states an outcome, and OS3 works out the rest by reasoning with connected AI models and whatever else the task calls for, including the web, services already in use, or connected devices. rabbit says OS3 runs in the cloud but connects to and operates devices through the rabbit agent, which installs with a single command, and that one account can be connected to up to five devices.

According to rabbit, OS3 decides where each task runs, on a single device or across several, moving work between them as the task requires and pulling any needed files, applications and skills along with it. The company says the whole system is built on a unified user identity that replaces isolated accounts and fragmented chat threads. rabbit lists two properties it says follow from that: multi-device orchestration, where OS3 determines the optimal device or combination of devices automatically instead of forcing users to choose between a local PC, a cloud VM or a dedicated AI computer, and one continuous conversation, with no session list or individual threads to manage, a single linear conversation that keeps track of past outputs and recalls what the user has told it before while continuing to work in the background.

rabbit says OS3 is open at the layers that matter to it: the model it runs on, the skills it can use, and the devices it can reach. The company describes three capabilities. First, bring-your-own-key flexibility, where users can power OS3 interchangeably with API keys from the latest models of frontier AI labs, cloud router platforms or locally hosted models, and swap models without affecting context, memory or skills. Second, universal skill compatibility, where rabbit says every skill published anywhere becomes something OS3 can do by copying the skill's URL and pasting it into chat, with no command line prompts or additional configuration files required. Third, direct computer control and autonomous coding, where rabbit says OS3 fuses the capabilities of an LLM with coding and personal agents, using its DLAM technology together with a local agent to operate desktop software, local files and web pages directly on a user's behalf, in addition to writing, debugging and running software workflows autonomously.

On data privacy and security, rabbit says OS3 can act on a user's behalf without giving up control of their data, and it lists three safeguards. The rabbit agent runs locally on the user's machine and does not copy, store, use or sell data, rabbit says, noting that as with any cloud-based assistant, conversations with OS3 and the memory built from them are stored on rabbit's servers but the files on the computer are not. Context is handled through the model provider, with relevant content sent to a connected model provider of the user's choice, which handles the data under its own terms; rabbit says that before this handoff the data is first processed through rabbit's servers along with any prompts needed to complete the task, and that rabbit does not keep a copy of this data while the files remain on the user's computer. OS3 also only takes user-initiated actions, rabbit says, does not run tasks on its own, requires confirmation for sensitive actions, requests system-level permissions locally from the operating system, and lets users revoke permission at any time.

rabbit frames OS3 as the capstone of work it says has run since its founding, pointing to the LAM behind r1 and to twelve consecutive months of upgrades delivered for rabbit devices, including rabbitOS 2, terminal mode and a move to bring-your-own-key support for DLAM. Jesse Lyu, Founder and CEO of rabbit, is quoted in the announcement saying that the company has spent two and a half years building toward a system you do not operate but instead just tell the outcome, and that by combining open skill compatibility with direct computer control, OS3 turns human intent into complex, multi-device action. On availability, rabbit says users can get started by visiting os3.rabbit.tech via desktop to log in or create a rabbit account and finish onboarding in a single conversation, then talk to OS3 through the web portal on desktop or mobile, a paired Telegram, iMessage, RCS or SMS, or rabbit's own r1, with additional input methods coming soon. rabbit says any device running the local rabbit agent can be controlled by OS3, naming Windows, Mac and Linux local PCs, cloud VMs, dedicated AI machines and the r1 today, with more device types to follow, and that its upcoming cyberdeck will ship with OS3 as its default operating system.
