What makes it different
Persistent filesystem across pause/resume without duplicating data
Pay only for compute time used; paused sandboxes have zero compute charges
Automatic filesystem growth so agents can install and persist unlimited tools
Same API for both human users and AI agents
Byte-verified hosted mirror with SHA-256 hashes for all open-source AI model files
Zero-account public access to catalog search and model downloads
Seamless integration across ChatGPT, Claude, Cursor, VS Code and other agent platforms via standardized MCP
