Rabbit launches OS3, an agentic AI platform for desktop, Telegram, and iMessage

Rabbit, the company behind the R1 AI device, has unveiled OS3, an agentic AI platform designed for desktop computers, Telegram, and iMessage messaging services. OS3 can interact with desktop programs, files, and web pages, and can write and debug code using its Direct Large Action Model (DLAM) technology. The platform is accessible through a browser, Telegram, iMessage, and works on the R1 device, which Rabbit is no longer manufacturing.

Users can connect up to five computers to a single OS3 account, and the system determines which machine should handle a request. Rabbit positions OS3 as a single, ongoing workspace rather than multiple chat windows. The service operates on a bring-your-own-key model, requiring users to provide API keys from companies like OpenAI or Anthropic, or use local open-source models.

Rabbit does not charge a subscription fee for OS3, but users must provide their own keys. The platform can install third-party agent skills from public URLs, aligning with Rabbit's goal of reducing its dependence on its own models and services. Rabbit has spent the past year and a half refining the R1, adding about 50 updates and opening the device to third-party agents, including OpenClaw and Hermes AI.

Despite initial excitement, the R1's agent features often failed to function as expected, leading to criticism. However, Rabbit shipped over 100,000 R1 units worldwide, maintaining a return rate below 5% and achieving gross margins of 45% to 50% on hardware. Founder and CEO Jesse Lyu emphasizes Rabbit's shift towards software, noting that the company raised $60 million and now employs 15 people.

The company faces financial pressure but is stable. Rabbit will continue selling the R1 while supplies last and plans to release a new device, the Cyberdeck, within months, which will also run OS3. OS3 does not store, copy, or sell user data from local files, keeping files on the user's computer. When a task requires AI-model reasoning, prompts are routed through Rabbit's systems to the user's chosen model provider.

Lyu has used OS3 for tasks like moving sales data from Excel to a master spreadsheet and representing himself in a Slack conversation with an engineer while unavailable. OS3 is now available to the public, allowing Rabbit to test whether its idea works better as software than as a standalone gadget.
