Rabbit makes its agentic system OS3 available in the cloud without requiring R1 hardware
Rabbit now offers the agentic OS3 without an R1 device — it runs in the cloud on Windows, Mac and Linux, through Telegram and iMessage, with up to five devices per account. It is also preparing a new “cyberdeck" device for vibe coding.
Rabbit has made its agentic operating system OS3 available independently of R1 hardware. According to the company, the system runs in the cloud but connects locally to Windows, Mac or Linux devices; up to five devices can be added to one account, each with its own preferred AI models. According to the company, OS3 is designed to automatically determine which devices, files, applications and models are needed to complete a task. Access is also possible through Telegram, iMessage or directly through an R1 device if the user owns one.
Rabbit does not charge a monthly subscription for OS3; users instead supply their own API keys from providers such as OpenAI or Anthropic, or connect local open-source models. According to the company, OS3 does not store, copy, use or sell data, but it retains chats and the “memories" derived from them on its servers; other AI providers connected to OS3 handle data according to their own policies.
Founder Jesse Lyu confirmed to Wired that production of the R1 device has ended, but the company is not giving up on hardware entirely — it is preparing a new device referred to as a “cyberdeck" focused on vibe coding, which is expected to arrive alongside the launch of OS3 within months. As context for the original R1 device, the company says that over 100 000 units have been sold with a return rate below 5 %, that it employs 15 people and that it has raised approximately 60 million dollars to date.
Why it matters
With this move, Rabbit is ending its dependence on its own hardware and opening OS3 to anyone with a standard computer or messaging app, expanding the potential user base compared with the previous model tied to the R1 device. The subscription-free model (BYOK) also shifts operating costs to users based on their own API usage, resulting in different economics from competing agentic assistants that charge a flat fee.

Two audiences, two different impacts
What this means
For individuals
Users can now try the OS3 agent without buying R1 hardware — all they need is a Windows, Mac or Linux computer, or Telegram or iMessage, and they can connect up to five devices under one account.
For a business
The company offers OS3 without a subscription (BYOK) — companies or teams that deploy the tool pay for API keys from model providers themselves, which changes the cost structure compared with standard AI assistants that charge a flat monthly fee.
