Lake
Version models, datasets, papers, and static/WASM Apps with Git, Git LFS, immutable releases, repository cards, local runners, and explicit access controls.
OSAII Platform catalog
Choose the space
for the work.
API and Studio are the focused entry points. These optional products share the Platform’s accounts, safety, and model infrastructure while retaining their own purpose and data boundaries.
Masque
Create, discover, and talk with enduring AI characters. Masque is an immersion-first product with its own profiles, sessions, memory, sharing, and moderation controls.
Cosaii
Cosaii, pronounced “cozy,” is a local-first developer agent — a downstream fork of Nous Research’s Hermes Agent with OSAII device login, scoped Platform inference, strict approvals, and the Agent Skill Repository. Conversations and files stay on your computer.
MythOS
A Debian-based desktop for people who want a computer, not a Linux hobby. OSAII web apps are optional and never required for MythOS to be useful.
Platform API
The shared OpenAI-compatible gateway for apps and scripts. Keys are optional for getting started and improve attribution and capacity when you use them.
Cosaii installation
Install the local agent.
The installer sets up Python tooling and the agent together. Then run cosaii login to authorize this computer with your Platform account.
