Isolated environments for reinforcement learning, agent tool use, and model evaluation on GPU infrastructure.
CoreWeave Sandboxes provides secure, isolated execution environments for running reinforcement learning, agent tool use, and model evaluation at scale. Available in preview, it supports both dedicated infrastructure through CKS and fully managed serverless runtime via Weights and Biases.
Teams can run hundreds of concurrent sandboxes with namespace isolation, configurable network policies, and controlled resource limits. The Python client enables launching, managing, and parallelizing sandbox workloads for ML and agent workflows with minimal overhead.
