## Choose when

### Choose auto-sklearn if…

- License: auto-sklearn is BSD-3-Clause, PhotoSketch is Other.
- Tags unique to auto-sklearn: automl, meta-learning, hyperparameter-search, hyperparameter-tuning.
- Also covers Model Training, Developer Tools.
- auto-sklearn ships Docker support for self-hosted deployment.

### Choose PhotoSketch if…

- License: PhotoSketch is Other, auto-sklearn is BSD-3-Clause.
- Tags unique to PhotoSketch: sketch, ai, python, graphics.
- Leaner open-issue backlog (5).

## When NOT to use auto-sklearn

- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.

## When NOT to use PhotoSketch

- Last GitHub push was 1159 days ago (dormant maintenance, May 10, 2023). Validate activity before betting a new project on PhotoSketch.
