About Polyaxon
Polyaxon is an open-source AI control plane designed to run on Kubernetes. It enables scheduling, tracking, and governance of AI/ML workloads, including GPU training, agent sessions, and sandboxes, all within self-hosted deployments. The platform supports training, services, and sandboxes using shared specs, queues, governance, and data connections.
It provides a unified interface for training and fine-tuning models, serving inference, running notebooks, and managing interactive sessions. Polyaxon integrates with various frameworks, clients, and APIs, and offers governance features such as organizations, teams, authentication, audit logs, and policies. It is suitable for teams that need to manage AI workloads on their own clusters and storage backends.
