[Digital Today reporter Chi-gyu Hwang (황치규)] Perplexity has unveiled Space, a sandbox platform designed to enhance the security and long-running task processing performance of its AI agent service, Computer.

On July 15 (local time), SiliconANGLE reported that Space is an isolated execution environment designed to let agents use full functionality while keeping sensitive information under user control. Perplexity Computer is a digital worker service that runs on Perplexity’s AI search engine. When users enter a goal in natural language, it breaks the task into multiple steps and combines more than 19 models, including Claude, Gemini and Grok, to carry out work such as web searches, email, Notion, Slack and data organization.

The service can remember past tasks and each user’s style. It can also continue working on its own after a user steps away, run on a schedule, or be set to operate based on changes in data.

Perplexity designed Space to address both security and session persistence issues in long-running tasks. Space groups sessions by sandbox and supports pausing, resuming and branched execution. It also manages each session’s credentials separately.

Each task runs inside an Amazon Web Services open-source virtual machine, the Firecracker microVM instance. Perplexity explained that this integrates pausing and resuming, session branching, separating and passing credentials by session, and orchestration functions into a single platform.

It does not store sensitive information such as passwords and keys inside the sandbox. This information is kept under a user’s own password and key management system and accessed only when needed. Information stored in the sandbox is also protected with encryption keys brought by the user, and if the user revokes the encryption keys, new sandboxes cannot read the data.
