Model Ensemble Orchestrator
Software componentModel ServingModelsarc:ModelEnsembleOrchestrator
An inference-server component that executes a declaratively defined multi-model pipeline server-side, feeding each model's outputs to the next without network round-trips.
Responsibility. Sequences, conditionally routes and parallelises model steps of an in-server inference pipeline.
Also known as: Triton ensemble, Inference orchestration engine

Design guidance
- SHOULD use for multi-step model pipelines (e.g., language detection, translation, intent extraction, generation) where latency matters, accepting tighter coupling between models.
- MUST account for all ensemble member models loading simultaneously when allocating resources.
