--- title: "katib vs hyperband" type: "comparison" canonical_url: "https://www.graphcanon.com/compare/kubeflow-katib-vs-zygmuntz-hyperband" tools: ["kubeflow-katib", "zygmuntz-hyperband"] --- # katib vs hyperband *GraphCanon updated Aug 4, 2026* ## Verdict Pick katib if katib is an automated machine learning solution for Kubernetes environments, focused on hyperparameter tuning and neural architecture search; pick hyperband if hyperband optimizes hyperparameters quickly with an efficient bandit-based approach, supporting several models from scikit-learn and polylearn. [katib](https://www.kubeflow.org/docs/components/katib) reports 1.7k GitHub stars, 534 forks, and 106 open issues, last pushed Aug 4, 2026. [hyperband](http://fastml.com/tuning-hyperparams-fast-with-hyperband/) has 599 stars, 73 forks, and 9 open issues, last pushed Aug 15, 2018. Figures are from public GitHub metadata via [katib's repository](https://github.com/kubeflow/katib) and [hyperband's repository](https://github.com/zygmuntz/hyperband). | | [katib](/tools/kubeflow-katib.md) | [hyperband](/tools/zygmuntz-hyperband.md) | | --- | --- | --- | | Tagline | Automated Machine Learning on Kubernetes | Tuning hyperparams fast with Hyperband | | Stars | 1,694 | 599 | | Forks | 534 | 73 | | Open issues | 106 | 9 | | Language | Python | Python | | Adopt for | Katib is an automated machine learning solution for Kubernetes environments, focused on hyperparameter tuning and neural architecture search. | Hyperband optimizes hyperparameters quickly with an efficient bandit-based approach, supporting several models from scikit-learn and polylearn. | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | Other | | Categories | Evaluation & Observability, Model Training | Model Training | ## Trust and health _Sourced signals - not a safety guarantee.
