Compute: $0.015 per GiB-hour (approximately $0.000004167 per GiB-second, billed by the second). Storage: $0.02 per GiB-month for retained incremental RootFS data and memory checkpoints. Network ingress and egress currently free. Object-store GET and PUT requests free. New users receive $5 free credi
Key features
Local LLM support with llama.cpp and MLX
Real-time voice transcription
Document creation and editing with auto-save
Coding tasks and automations
Cloud inference with frontier models
Web search and page extraction
Multi-language voice support
LM Link for device sharing
Automatic filesystem growth as storage fills
Pause compute without losing work or paying compute charges
Resume to same environment on demand
Access files while paused without waking compute
Public HTTP services with auto-resume capability
Command-line interface (s0 CLI) for agent-native workflows
Incremental checkpoints to avoid full filesystem copies
Scoped API keys and team-based access controls
On-demand file reads without downloading entire filesystem
What makes it different
Natively local processing with privacy guarantees
Zero Data Retention across all cloud services
Access to frontier open models
Agentic capabilities for work and code
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
