Choose data-juicer if…
- Tags unique to data-juicer: foundation-models, instruction-tuning, large language models, llm.
- Also covers Model Training.
- data-juicer ships Docker support for self-hosted deployment.
- When you need to preprocess large datasets specifically for training large language models (LLMs) with pipelines that support sophisticated processes like instruction tuning.
When NOT to use data-juicer
- If your project does not involve foundational AI model training or if you do not require advanced data processing capabilities such as synthetic data generation.
Choose great_expectations if…
- Requirements: Supports Python versions 3.10 through 3.13, with experimental support for Python 3.14 and later via an environment variable..
- Tags unique to great_expectations: data-engineering, data-quality, exploratory-data-analysis, mlops.
- When you need detailed and automated documentation for each set of validation results to simplify your data quality processes while preserving institutional knowledge.
When NOT to use great_expectations
- For environments that strictly require adherence to Python versions 3.9 or lower, since Great Expectations supports only 3.10 through 3.13 natively.
- If your data integration requirements are not compatible with those listed in the Great Expectations compatibility reference.
