Built on Cloudflare’s existing Workers platform, Dynamic Workers uses V8 isolates to execute code generated at runtime, often by LLMs, without requiring a full container or virtual machine.
“An isolate takes a few milliseconds to start and uses a few megabytes of memory,” Cloudflare said in a blog post. “That’s around 100x faster and 10x-100x more memory efficient than a typical container. That means that if you want to start a new isolate for every user request, on-demand, to run one snippet of code, then throw it away, you can.”
Cloudflare is pairing the runtime with its “Code Mode” approach, which encourages models to write short TypeScript functions against defined APIs instead of relying on multiple tool calls, a method the company says can reduce token usage and latency.
