## When it is useful

ML workload patterns: model training, hyperparameter optimization, experiment tracking.

## The Catch

Loud: Flyte OSS Apache-2.0 — local/devbox $0 forever; Flyte 1 self-host on your K8s $0. Official repo: Flyte 2 distributed OSS backend is coming soon — production Flyte 2 backend today is Union.ai (paid; do not invent free forever Cloud). Distinct from ZenML CA (MLOps pipelines vs K8s-native workflow orchestration). Skills Apache-2.0.
