LithosAI launches LithosBox: millisecond snapshot-and-fork sandboxes for AI agents
JiaZhihao · x · 2026-10-03
LithosAI has released a public preview of LithosBox, an ultra-fast versioned sandbox system built for AI agents, supporting snapshotting, forking, and restoring environments in milliseconds.
- The company previously focused on ultra-low-latency inference for open models like Kimi K3, DeepSeek V4.1, and GLM 5.3 Flash, and is now extending to agent runtime and post-training environments with Git-like version control
- Agents can spin up thousands of environments to explore parallel paths, pick a winner, rebuild the winning state, and discard the rest — all in milliseconds
- The team built an agent-vs-agent Doom showdown to demonstrate the co-designed low-latency serving infrastructure, claiming up to 5x faster agent runs
