Polyaxon

Polyaxon is an AI control plane that schedules, runs, and governs machine learning workloads and agent sessions on Kubernetes infrastructure.

Polyaxon acts as an open-source AI control plane designed to manage training, fine-tuning, inference, and interactive notebooks on your own Kubernetes clusters. It allows teams to orchestrate complex workflows, manage resources, and enforce governance without moving data outside controlled environments. The platform integrates with popular frameworks like PyTorch, TensorFlow, JAX, and XGBoost, supporting distributed jobs and multi-node execution. It provides a unified interface for tracking experiments, capturing lineage, and handling logs and artifacts across cloud and on-premise setups. Engineers can interact with the system using a dedicated command-line interface, SDKs, and REST or gRPC APIs.
