## Choose when

### Choose lightly if…

- License: lightly is MIT, pixeltable is Apache-2.0.
- Tags unique to lightly: contrastive-learning, deep-learning, embeddings, self-supervised-learning.
- You need to enhance model performance with unlabeled image data.

### Choose pixeltable if…

- License: pixeltable is Apache-2.0, lightly is MIT.
- Tags unique to pixeltable: ai, artificial-intelligence, chatbot, data-science.
- Also covers Data & Retrieval.
- When your project requires seamless integration of both image processing and traditional ML tasks under one robust framework.

## When NOT to use lightly

- Labeled datasets are abundant and of high quality for your use case.
- Project requirements strictly limit the use of Python-based libraries.

## When NOT to use pixeltable

- For teams focused solely on monomodal tasks or those who need specialized tools that offer deeper functionality in specific areas such as audio processing alone.
- If your development team has a strong preference for languages other than Python, given PixelTable's reliance on the Python ecosystem.
- When strict control over every aspect of model training and feature engineering is required, as PixelTable provides a more integrated solution that might limit granular customization.
