Overview
- OS3 became generally available on Tuesday, Sept. 22, 2026, and Rabbit is offering it as a cloud‑coordinated agent that users can access from a desktop site, Telegram, iMessage or an existing R1 device.
- The system uses local agent nodes on Windows, macOS and Linux to execute actions and relies on two company technologies called the Large Action Model (LAM) for intent and the Direct Large Action Model (DLAM) for direct control of software interfaces.
- Rabbit uses a bring‑your‑own‑key model so users supply API keys from providers like OpenAI or Anthropic or link local models, and the company says there is no monthly subscription fee.
- Rabbit says chats and memory logs are stored on its servers while file contents remain on users' machines, but it routes prompts through its servers to external model providers, a design that raises open questions about real‑world privacy and security.
- The company has stopped manufacturing the R1 and has no R2 planned, plans to ship a cyberdeck running OS3 within months, and independent testing of OS3's reliability and safety has not yet been published, leaving regulators and users to watch for performance and data‑handling issues.
