About AIOS
AIOS is listed in our frameworks category and is aimed at builders. Research AI agent operating system that handles scheduling, context switching, memory, storage and tool management for LLM-based agents. Pricing, as the maker states it: Free to download on GitHub; no licence declared (empty LICENSE file). Maturity: Mature. We last checked the official link on 2026-10-21.
What is AIOS?
AIOS, from the AGI Research group, is an 'AI agent operating system' that embeds a language model into the operating system layer. Its kernel manages what agents need, such as LLM access, scheduling, context switching, memory, storage and tools, while the separate Cerebrum SDK is used to build and run agents on top.
It offers a web UI and a terminal UI, and a computer-use variant extends the kernel with a VM controller and an MCP server so agents can operate a desktop safely. It is a research project with accompanying papers rather than a commercial product.
