Perplexity open-sources SPACE, its sandbox platform for running AI agent code

Perplexity has released SPACE, the sandbox platform that has run its Computer agent's sessions since July, as open source under the Apache 2.0 license on GitHub. Each sandbox is a Firecracker microVM with its own operating system, managed by a central control plane that handles creating, pausing, resuming and removing them. Network access and credentials are kept outside the sandbox so agents can reach authorized services without storing keys in their workspace. Perplexity says the platform supports millions of sandbox creations daily and that creation ran 3 to 5 times faster than its previous provider. A prior security report found that while the virtual machines held up against escape attempts, four models bypassed the network egress policy in some runs, a weakness Perplexity says it has since fixed.
