Pricing
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
Free in test mode with 2 hours of computer time per day. Live mode: computers $0.0000556 per second ($0.20 per hour), billed by the second while awake. Claude Sonnet 5.5 (default): $1.92 per million input tokens, $9.60 per million output tokens. Language models from $0.096 to $9.60 per million input
Key features
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
Run agents from Claude Code, Codex, pi or Ugoko's own agent
Language models from Claude, Kimi, GLM, Grok and GPT
Image, video, audio and speech generation
Per-end-user budgets and metering
Computer sleeps free after 5 idle minutes
Command-line interface with one-command setup
Test mode free with real computer time
No failed generation charges
Webhooks and event streaming
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
Pay only for computer time while awake, with sleep cost-free
One project balance for all: computers, all language models and all media models
Includes Claude Code, Codex and preview harnesses with no separate gateway to build
Failed jobs are free; pay only for successful generations
