Glossary

Workspace — Your team's slice of the Vantage cluster, with quota, RBAC, and a cost envelope.

Cluster — A physical Kubernetes cluster Vantage manages. Workspaces live inside clusters; users can switch between clusters their team has access to.

Compute profile — Reusable shape of compute (GPU + count + instance type + bounds).

Session — An interactive notebook environment.

Model — A registered, versioned artifact in the catalog.

Endpoint — An inference service serving a model behind an HTTP URL.

Training job — A finite, distributed training run.

Pipeline — A multi-step DAG of containerized tasks.

Sweep — A hyperparameter-search experiment containing many trial runs.

Trial — One concrete run inside a sweep, with one specific parameter combination.

Initializer — A pre-training step that fetches a dataset or base model into local cache.

Runtime — A pre-built training environment — framework + image + parallelism strategy.

Canary — A new endpoint version receiving a fraction of traffic during a rollout.

Idle spend — Cost accrued by compute that's reserved but not running work (typically GPU util < 5%).
