As AI agents increasingly generate and execute code in real-time, the infrastructure layer that runs this code is becoming competitive—sandbox providers are optimizing for near-instant environment initialization rather than traditional container startup delays. Agent-generated code's value depends on rapid iteration cycles; slower sandboxes make AI coding assistants feel laggy and unreliable, while millisecond starts enable interactive development experiences. The winners in this race will embed themselves in enterprise AI coding pipelines, making sandbox performance a critical component of AI productivity.
