## Choose when

### Choose data-juicer if…

- data-juicer is primarily Python; fiftyone is TypeScript.
- Tags unique to data-juicer: data, data pipeline, data-analysis, data-processing.
- Also covers LLM Frameworks, Model Training.
- You need advanced data processing capabilities tailored specifically for foundation or large language models.

### Choose fiftyone if…

- fiftyone is primarily TypeScript; data-juicer is Python.
- Tags unique to fiftyone: active-learning, artificial-intelligence, computer-vision, data-centric-ai.
- Also covers Computer Vision, Developer Tools.
- When you need a comprehensive solution for both dataset refinement and visualization tailored for computer vision projects, Fiftyone stands out.

## When NOT to use data-juicer

- If your requirement is restricted to general data processing and analysis without focus on large language models or foundation models, other general-purpose tools might suffice.
- When the dataset you're handling involves minimal use of text-based operations that don't benefit from advanced natural language processing techniques specific to DataJuicer.
- In situations where you require live, real-time data transformations outside typical batch-processing pipelines which this tool is optimized for.

## When NOT to use fiftyone

- If your primary focus is not within the realm of computer vision or unstructured data handling, Fiftyone may not align with your needs.
- Consider alternatives if your project does not require TypeScript; Fiftyone’s choice of language might create a compatibility barrier for projects preferring other languages.
