## Deployment configuration

[Model Deployment Configuration](/gpustack-operator/main/docs/modules/model-deployment/deployment/index.md) starts with a minimal manifest and explains
the role contract. [Prefill and Decode](/gpustack-operator/main/docs/modules/model-deployment/prefill-decode/index.md) covers split roles.
[Engine Versions](/gpustack-operator/main/docs/modules/model-deployment/engine-versions/index.md) records tested version floors.

## Service operations

[Status](/gpustack-operator/main/docs/modules/model-deployment/status/index.md), [Metrics](/gpustack-operator/main/docs/modules/model-deployment/metrics/index.md) and
[Routing](/gpustack-operator/main/docs/modules/model-deployment/routing/index.md) explain what the running service reports and how requests
are directed.
