TL;DR
- AI agents require deterministic execution for tasks like data analysis, chart generation, and calculations.
- Perplexity's Sandbox API offers isolated code execution environments, previously used internally by Perplexity Computer, Finance Agent, and Deep Research.
- Sessions are stateful, running in isolated Kubernetes pods with persistent filesystems via FUSE, supporting Python, JavaScript, and SQL.
- The system operates on a zero-trust security model, with no direct network access for sandboxes and traffic routed through an egress proxy.
- Sandbox API will be integrated as a tool within Agent API, allowing agents to delegate computations and maintain their reasoning loop.
- A private beta for Sandbox API is opening soon, with documentation available at docs.perplexity.ai.
