Vercel 針對其沙盒（Sandbox）環境的快照（Snapshot）技術進行了重大優化。透過改進記憶體狀態保存與恢復機制，新技術能顯著縮短微型虛擬機（microVM）的冷啟動時間。這項改進將直接惠及 v0 等 AI 程式碼生成工具的即時預覽功能，以及 Vercel 平台上的無伺服器與邊緣運算服務，為開發者提供更流暢的部署與測試體驗。
Vercel has recently conducted deep optimization of the snapshot technology for its sandbox environments, aiming to address the common "cold start" latency problem in server-side execution environments. In modern cloud and AI application architectures, sandbox environments (typically based on microVMs such as Firecracker) are widely used to securely isolate and execute user code. However, starting a new sandbox from scratch each time takes several seconds — a significant pain point for applications that require immediate feedback (such as the real-time preview in Vercel's AI web generation tool v0, or dynamic server-side rendering).
