Prime Intellect has open-sourced Prime Sandboxes, a set of MicroVM sandboxes purpose-built for RL training, now available publicly.
- Training runs often require tens of thousands of concurrent sandboxes, leading to complex and costly configuration; the team built this system for their own research team before releasing it.
- A researcher noted the sandboxes were battle-tested extensively before launch.
- The product targets a core infrastructure pain point in RL training at scale.
