The Kubernetes-native workflow orchestrator for scalable and type-safe ML and data pipelines.

Scalable, Kubernetes-native Hyperparameter Tuning and Neural Architecture Search for production-grade ML.

Kubeflow Katib is the industry-standard Kubernetes-native framework for automated machine learning (AutoML), specifically focusing on Hyperparameter Tuning (HPT) and Neural Architecture Search (NAS). In the 2026 market landscape, Katib remains the premier choice for organizations building 'Sovereign AI' on private or hybrid cloud infrastructures. Its architecture is decoupled from specific ML frameworks, allowing it to optimize models written in PyTorch, TensorFlow, MXNet, and XGBoost by treating them as containerized workloads. Katib functions by managing Experiments through Kubernetes Custom Resource Definitions (CRDs), orchestrating 'Trials' to identify the most efficient parameter configurations. Its value proposition in 2026 is driven by its ability to integrate deeply with the broader Kubeflow ecosystem—such as Pipelines and Training Operators—while providing advanced algorithms like Hyperband and Bayesian Optimization. For enterprise architects, Katib provides a bridge between data science research and production-scale resource efficiency, ensuring that high-performance models are not just accurate, but also resource-optimized for GPU/TPU environments. Its cloud-agnostic nature prevents vendor lock-in, making it a critical component for large-scale distributed training clusters.

Explore all tools that specialize in algorithm benchmarking. This domain focus ensures Kubeflow Katib delivers optimized results for this specific requirement.
Uses a suggestion service architecture allowing users to plug in custom optimization algorithms as gRPC services.
Supports ENAS and DARTS to automatically design the optimal neural network topology.
Implements Median Stopping Rule and other algorithms to terminate underperforming trials early.
Automatically injects sidecar containers to scrape logs and metrics (Stdout, File, Prometheus) without modifying training code.
Agnostic Trial templates that run any containerized application.
Orchestrates parallel trial execution across multiple nodes and GPU pools.
Native Python SDK for programmatically defining and launching experiments within Jupyter Notebooks.
Install Kubernetes cluster (v1.28+) and configure kubectl access.
Deploy Katib using Kustomize: 'kubectl apply -k github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-standalone'.
Verify the Katib controller and DB components are running in the 'kubeflow' namespace.
Define an Experiment YAML specifying the objective metric (e.g., Validation-Accuracy).
Configure the Search Space by defining parameter ranges (int, double, categorical).
Choose a Search Algorithm (e.g., random, tpe, bayesianoptimization, hyperband).
Define the Trial Template, pointing to your training container image.
Submit the Experiment: 'kubectl apply -f my-experiment.yaml'.
Monitor progress via the Katib UI or 'kubectl describe experiment <name>'.
Extract the 'Best Parameter Set' from the Experiment status for final model training.
All Set
Ready to go
Verified feedback from other users.
"Highly praised for its Kubernetes-native design and scalability, though users find the YAML configuration verbose and the UI occasionally lagging behind features."
