Cloudflare’s new Dynamic Workers ditch containers to run AI agent code 100x faster

Web infrastructure giant Cloudflare is seeking to transform the way enterprises deploy AI agents with the open beta release of Dynamic Workers, a new lightweight, isolate-based sandboxing system that it says starts in milliseconds, uses only a few megabytes of memory, and can run on the same machine — even the same thread — as the request that created it. Compared with traditional Linux containers, the company says that makes Dynamic Workers roughly 100x faster to start and between 10x and 100x more memory efficient.Cloudflare has spent months pushing what it calls “Code Mode,” the idea that large language models often perform better when they are given an API and asked to write code against it, rather than being forced into one tool call after another.
