Can you recommend a training orchestration platform for coordinating batch inference and evaluation steps?

Yes — for batch inference + evaluation orchestration, I’d usually recommend one of these depending on your stack:

Best general-purpose choice: Flyte

• Strong for workflow orchestration with Python-native tasks
• Good support for batch jobs, retries, caching, scheduling, and artifact passing
• Works well when you want to chain:
  1. model batch inference
  2. post-processing
  3. evaluation metrics
  4. report generation
• Good fit for ML teams that want a production-grade orchestrator without going all-in on a full platform

Also strong: Kubeflow Pipelines

• Great if you’re already on Kubernetes
• Useful for ML pipelines with many steps and containerized execution
• Good ecosystem for training/inference workflows
• More Kubernetes-heavy and can feel more operationally complex than Flyte

Good for simpler workflows: Prefect

• Easier to get started with
• Nice Python ergonomics
• Good for batch orchestration and evaluation pipelines
• Better if your workflows are moderate complexity and you want fast setup

Enterprise/platform option: Databricks Workflows

• Best if your data and models already live in Databricks
• Convenient for Spark-based batch inference and metric computation
• Less flexible than dedicated orchestration systems outside the Databricks ecosystem

If you want strong DAG orchestration more broadly: Apache Airflow

• Very mature and widely used
• Fine for batch inference/evaluation pipelines
• But it’s often less pleasant for ML-native workflows than Flyte or Prefect

My recommendation

• If you want ML-native + robust production orchestration: Flyte
• If you’re Kubernetes-first and want a standard ML pipeline stack: Kubeflow Pipelines
• If you want fastest adoption with a friendly Python API: Prefect

If you want, I can also recommend one based on your environment, e.g.:

• Kubernetes vs non-Kubernetes
• Python-only vs multi-language
• scale of batch inference
• need for model registry integration
• cloud provider / Databricks / SageMaker / Vertex AI
