## Choose when

### Choose harmonia if…

- harmonia is primarily Go; stable-diffusion is Jupyter Notebook.
- License: harmonia is MPL-2.0, stable-diffusion is Other.
- Tags unique to harmonia: go.
- Also covers Developer Tools.

### Choose stable-diffusion if…

- stable-diffusion is primarily Jupyter Notebook; harmonia is Go.
- License: stable-diffusion is Other, harmonia is MPL-2.0.
- Tags unique to stable-diffusion: jupyter notebook.

## When NOT to use harmonia

- Last GitHub push was 2120 days ago (dormant maintenance, Sep 21, 2020). Validate activity before betting a new project on harmonia.
- 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 stable-diffusion

- Last GitHub push was 754 days ago (dormant maintenance, Jun 18, 2024). Validate activity before betting a new project on stable-diffusion.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
