MicroVM sandboxes with 25ms suspend/resume
Blaxel built isolated microVM sandboxes for agents, enabling safe code execution and state persistence. They suspend and resume in 25 milliseconds—up to 5× faster than other sandbox products—and can remain idle for months at near-zero cost while retaining state.

Original excerpt
Every agent gets its own microVM. We made them extremely fast: suspend and resume in 25 milliseconds, up to 5x faster than other sandbox products. A sandbox can sit idle for months at close to zero cost and come back before the model finishes its next sentence, so state persists without paying for compute you aren't using.
Context
Sandboxes came first because nothing else works without them. Agents write and run code, call tools, and carry state across long tasks, and you can't do that safely in a shared process.
