Sigma AI Defines New Standards for Quality Annotation in Generative AI

As enterprises face increased risk from AI hallucination and misinformation, Sigma Truth evolves benchmarks beyond accuracy

MIAMI, FL, UNITED STATES, September 30, 2025 /EINPresswire.com/ -- Sigma AI, The Human Context Company and a global leader in human‑in‑the‑loop data annotation, today announced new standards for evaluating and improving the quality of generative AI outputs. As enterprises rapidly adopt large language models (LLMs), the company is calling attention to a major industry challenge: the old benchmark of 99.99% accuracy — the gold standard for traditional, binary AI tasks — no longer applies when evaluating open‑ended, generative responses.

Unlike traditional AI systems, which could be measured by simple right‑or‑wrong outputs, LLMs generate nuanced, contextual responses that demand far more than surface‑level accuracy. “Truth” in generative AI requires evaluating factual grounding, coherence, attribution, tone, and context, criteria that legacy accuracy metrics often fail to capture. According to Gartner, “By 2027, 45% of organizations worldwide will experience a generative AI data quality issue leading to visible errors in decision‑making or customer experience.”

These stakes are driving companies to seek new, human‑centered approaches to validating and training their models. “Quality in generative AI isn’t binary, and it isn’t simple,” said Daniel Tapias, CEO of Sigma AI. “It’s about teaching machines to reason with nuance. Accuracy alone is not enough when AI must respond to open‑ended questions, handle ambiguity, and synthesize across sources. You need human judgment layered in. That’s why we built Sigma Truth: to help enterprises deliver outputs that are not just technically correct, but contextually trustworthy.”

Sigma Truth offers workflows such as ground‑truth validation, factuality scoring, attribution checks, and iterative multi‑pass reviews. Trained annotators and subject matter experts evaluate AI outputs against trusted references, flag hallucinations, and rewrite responses when needed, creating a feedback loop that aligns LLMs with real‑world expectations.

Through live calibration, inter‑annotator agreement benchmarks, and continuous refinement, Sigma helps clients create trustworthy AI systems. Organizations from healthcare, financial services, and enterprise software are already adopting these new quality standards to reduce risk, avoid misinformation, and unlock more value from their AI investments.
