Shared compatibility
- Python · katib: Python runtime · FLAML: Python runtime
Choose katib if…
- katib is primarily Python; FLAML is Jupyter Notebook.
- License: katib is Apache-2.0, FLAML is MIT.
- Tags unique to katib: ai, automl, hyperparameter-tuning, neural-architecture-search.
- When you need to perform comprehensive hyperparameter tuning tasks within a Kubernetes cluster setup.
When NOT to use katib
- Avoid using Katib if you do not have a Kubernetes cluster setup, as it heavily relies on this platform for operation.
- If your project's requirements do not extend beyond simple model training tasks and you lack the resources to support a complex CI/CD pipeline like Kubeflow with Katib.
- Not suitable when working in environments with strict constraints preventing the use of open-source tools under Apache-2.0 licenses.
Choose FLAML if…
- FLAML is primarily Jupyter Notebook; katib is Python.
- License: FLAML is MIT, katib is Apache-2.0.
- Tags unique to FLAML: automated-machine-learning, classification, data-science, deep-learning.
- FLAML ships Docker support for self-hosted deployment.
- When working with Python >= 3.10 and < 3.14 to ensure full support of all models in FLAML.
When NOT to use FLAML
- When your project is restricted to using Python versions below 3.10 or equal to and above 3.14, as FLAML's full feature support may not be available.
- If the scope of work does not include AutoML tasks such as hyperparameter optimization or model selection for classification, regression, NLP, or time-series forecasting.
- For users who need cross-language compatibility beyond Python and Jupyter Notebook environments; FLAML primarily supports Python-based operations.
