Your guide to quality for generative AI

Generative AI can’t be judged by “right vs. wrong” alone. This research report reframes quality for open-ended, context-rich tasks and defines 10 concrete markers, from cultural sensitivity and domain expertise to coherence, creativity, and bias mitigation. You’ll see how expert human annotation, live calibration, and inter-annotator agreement (IAA) turn nuance into measurable quality, reducing hallucinations and improving trust in production LLMs.

Inside the report...

This whitepaper provides critical insights to ensure your gen AI projects are built on a foundation of high-quality, well-validated data:

  • The 10 quality markers for generative AI annotation—and how each is measured (e.g., IAA, expert review, bias audits).
  • The skills great annotators need for gen AI (linguistics, domain knowledge, critical judgment, creative thinking).
  • Why accuracy alone fails for open-ended tasks, and what replaces it: nuance, context, citation, and coherence.
  • Strategies that raise quality at scale: multi-pass review, preference ranking, diverse annotator pools, and calibration loops.
  • Research-backed risks to watch (hallucinations, cultural blind spots, shallow summaries) and how to mitigate them.

The success of generative AI hinges on more than accuracy — it requires human-annotated data that captures nuance, context, and creativity.

Quality extends beyond error-free labels to cultural sensitivity, contextual reasoning, language logic, and prioritization.
