Validate activity before betting a new project on RGB. ## Common questions ### What is the difference between auto-sklearn and RGB? auto-sklearn: Automated Machine Learning with scikit-learn. RGB: Incomplete metadata; License information provided. See the comparison table for live GitHub stats and shared categories. ### When should I choose auto-sklearn over RGB? Choose auto-sklearn over RGB when License: auto-sklearn is BSD-3-Clause, RGB is Other; Tags unique to auto-sklearn: automated-machine-learning, automl, bayesian-optimization, hyperparameter-optimization; Also covers Developer Tools, Model Training; auto-sklearn ships Docker support for self-hosted deployment. ### When should I choose RGB over auto-sklearn? Choose RGB over auto-sklearn when License: RGB is Other, auto-sklearn is BSD-3-Clause; Tags unique to RGB: license information, python; Leaner open-issue backlog (17). ### When should I avoid auto-sklearn? Developer Tools: A gateway is overkill when you're pinned to a single provider and model. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### When should I avoid RGB?
