Prime Intellect open-sources Prime Sandboxes: microVMs purpose-built for agentic RL training

Prime Intellect launched Prime Sandboxes, microVM sandboxes purpose-built for large-scale agentic RL training, now available publicly.
The team couldn't find sandboxes that could handle the scale of their RL training — model training requires running tens of thousands of concurrent sandboxes, leading to complex and costly configuration — so they built their own and are releasing it.
