The Human Edge in AI: GLG Frontier Powers AI Labs with Critical Expert Judgment

New dedicated practice answers growing demand for trusted, specialized expertise to develop and evaluate models responsibly 

NEW YORK, Oct. 15, 2026 /PRNewswire/ -- GLG, the world's leading platform for trusted human expertise, today announced the launch of GLG Frontier, a practice dedicated to providing AI labs and model developers with the verified expertise and structured data needed to evaluate, fine-tune, stress-test, and benchmark models at scale.

"As frontier models push into medicine, law, biosafety, and national security, they increasingly demand the right expert judgment," said GLG CEO Gemma Postlethwaite. "GLG has spent decades building the infrastructure to rigorously source and vet that trusted expertise, at the speed and scale the labs require. GLG Frontier brings that capability directly to model development at the moment the industry needs it most."

GLG Frontier brings new scale to the work GLG has conducted with frontier labs since AI model training began, meeting sharply rising demand for distinctive expert engagement as models continue to push into higher-consequence domains. Unlike what scaled human data providers and crowdsourced platforms offer, GLG experts can contribute as both architects and operators, helping to design evaluations, construct benchmarks, red-team security infrastructure, develop reasonable deployment standards, and even identify further key expertise gaps. Recently published case studies show the impact such work has produced across an array of model development projects, covering drug policy, mental health, nuclear risks, biosafety, extreme weather forecasting, and more. In each case, GLG sourced multidisciplinary panels of top experts in hours, who were able to mitigate acute risks in frontier models where robust data sets fell short.

To lead the new dedicated practice, GLG has appointed Grady Gardner as General Manager of GLG Frontier. Gardner brings deep experience in AI model training and human data, most recently as GM and Chief Revenue Officer at Braintrust, where he built AI training-data programs for frontier labs and model builders.

"Labs are expanding into more specialized and higher-consequence territory, where there's no margin for error," said Gardner. "GLG has the infrastructure, credibility, and compliance rigor to serve a critical need – providing one-of-one experts who can not only annotate outputs, but help design the rigorous evaluations, benchmarks, and safety standards that determine whether a model is ready for deployment."

GLG Frontier engagements are available as targeted expert projects or sustained multi-month programs, with expert composition updated as the work evolves. The rapid, precise sourcing and matching process follows GLG's proven methodology and compliance framework and taps the company's unparalleled global network of trusted top experts, including experienced, credentialed professionals across medicine, science, law, finance, and engineering.
