Story

The open beta lets agents execute code in V8 isolates that start in milliseconds, roughly 100x faster to boot and 10-100x more memory efficient than containers. JavaScript-first with Python and WASM support. If you're running AI-generated code in Docker containers, this is cheaper and more secure. The pricing is negligible compared to inference costs.
