OS3 is an agentic operating system by rabbit inc. that executes tasks on connected devices through a central chat interface instead of classic apps. It runs on the cloud, controls up to five devices (Windows, Mac, Linux, Cloud-VMs, AI compute, and the r1 device) via a locally installed agent, and uses Direct Large Action Model (DLAM) technology for direct screen and application control. The product is based on a bring-your-own-key (BYOK) model, supports any "universal Skills" that can be integrated via URL, and is available without a subscription fee as long as users provide their own API keys. General availability began on September 22, 2026.
