What is Polyaxon?
Polyaxon schedules, tracks and governs machine learning work on your own Kubernetes clusters, from GPU training and fine-tuning to model serving and agent sandboxes. It is an open-source platform with paid tiers for teams that need more seats and controls.
Jobs are described in Polyaxonfiles written in YAML, JSON, Python, Go or TypeScript, and cover fine-tuning with LoRA, RL, hyperparameter sweeps, DAGs and batch runs from one GPU to many nodes. Services such as inference endpoints, notebooks and TensorBoard share the same queues and data connections.
Teams get experiment tracking, comparison dashboards, evals and a model registry, plus audit logs and access policies. Because it runs on your own clouds, on-prem clusters and storage, training data stays in infrastructure you control.
