FAQ
Is the data you deliver ready for fine-tuning?
Yes, all datasets are structured in JSONL format and optimized for fine-tuning with platforms like OpenAI, Hugging Face, and Cohere.
Do you support bilingual or multilingual datasets?
Absolutely! I provide datasets in English and Spanish by default, and can support other languages upon request.
Can I request a specific structure or format?
Yes. I can adapt the dataset structure to fit your training pipeline needs (CSV, JSON, JSONL, XLSX, etc.).
Do you include metadata or documentation?
Yes. I provide optional schema documentation, field definitions, and file structure guidance.
Is the data annotated manually or generated automatically?
All annotations are done manually and contextually, ensuring semantic accuracy and high-quality training data.
