“Stateful systems are incredibly hard to build”: How Perplexity thinks about AI agent sandboxes
The New Stack Frederic Lardinois
Perplexity launched SPACE, a sandbox platform for its Computer AI agent service, focusing on managing persistent state across long-running agent sessions rather than just isolation. The system uses Btrfs filesystem for cheap snapshots and can pause, resume, and fork sessions that run for days or weeks, with snapshots taken as frequently as every minute and ability to rewind up to a week. This approach delivers 3x performance improvements and significant cost savings compared to existing sandbox providers, while establishing a new constraint on CPU resources alongside GPU demands as agents take on longer workloads.
Why it matters
Sandboxes for AI agents may feel like a solved problem. After all, projects like Firecracker, the open-source microVM technology AWS built The post “Stateful systems are incredibly hard to build”: How Perplexity thinks about AI agent sandboxes appeared first on The New Stack.
