Katib is a Kubernetes-native project for automated machine learning (AutoML). Katib supports Hyperparameter Tuning, Early Stopping and Neural Architecture Search.
Katib is the project which is agnostic to machine learning (ML) frameworks. It can tune hyperparameters of applications written in any language of the users’ choice and natively supports many ML frameworks, such as TensorFlow, Apache MXNet, PyTorch, XGBoost, and others.
Katib can perform training jobs using any Kubernetes Custom Resources with out of the box support for Kubeflow Training Operator, Argo Workflows, Tekton Pipelines and many more.
Katib stands for secretary in Arabic.
Katib supports several search algorithms. Follow the Kubeflow documentation to know more about each algorithm and check the Suggestion service guide to implement your custom algorithm.

To perform above algorithms Katib supports the following frameworks:
For the various Katib installs check the Kubeflow guide. Follow the next steps to install Katib standalone.
This is the minimal requirements to install Katib:
- Kubernetes >= 1.17
kubectl>= 1.21
For the latest Katib version run this command:
kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-standalone?ref=master"
For the specific Katib release (for example v0.13.0) run this command:
kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-standalone?ref=v0.13.0"
Make sure that all Katib components are running:
$ kubectl get pods -n kubeflow
