AI fine-tuning data quality requires a 'judge' model, not just generation

Generating high-quality synthetic data for fine-tuning language models is challenging, as many automated methods produce samples that are irrelevant, factually inconsistent, poorly formatted, or unhelpful. A common pitfall is relying solely on a generation prompt, which can lead to model drift and degraded output quality over time. To address this, a "judge" stage employing a separate, more capable model is recommended to evaluate each generated sample against specific criteria like relevance, factual consistency, format quality, and usefulness, ensuring only high-caliber data is used for training.
