Choose data-juicer if…
- Tags unique to data-juicer: foundation-models, instruction-tuning, large language models, llm.
- 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 Curator if…
- Tags unique to Curator: curation toolkit, data pre-processing, deduplication, llms.
- You're working with NVIDIA NeMo models and require seamless integration.
When NOT to use Curator
- Your dataset doesn't align with NVIDIA hardware specifications.
- You prefer data curation tools that do not emphasize semantic processing.
