The Harvard T.H. Chan School of Public Health recently hosted a four-part pilot series designed to evaluate the practical utility and inherent limitations of generative AI. Over 100 participants attended the sessions, which addressed AI implementation in scholarly research, data analysis, and hiring workflows.
Why it matters
The pilot highlights the growing necessity for academic institutions to establish rigorous frameworks for assessing AI outputs, particularly as reliance on these models for research tasks increases. The series aimed to develop critical judgment in navigating the technical constraints of large language models.
The series demonstrated that while LLMs can automate tasks like email generation and data summarization, they consistently struggle with verifying truth and communicating uncertainty. Additionally, proprietary subscription models currently prevent these models from accessing specific, closed-access research databases.
The players
Harvard T.H. Chan School of Public Health
An academic institution focused on public health research and education.
Countway Library
A research library providing expertise on scholarly resources and data evaluation.
The details
The program featured librarians and faculty who demonstrated how to evaluate AI-generated outputs, including testing datasets and citations for hallucinations—instances where an AI produces false or misleading information. Participants utilized LLMs to generate text, captions, and notes, identifying limitations where models failed to flag missing source data. This evaluation process helped clarify why LLMs cannot be relied upon for critical research analysis without manual verification of every generated claim.
Timeline
The pilot series sessions began in mid-September 2026.
The series concluded in early October 2026.
The Tech Race
This program reflects a broader trend among major research universities to standardize the evaluation of generative AI tools within academic pipelines. It signals a move away from passive AI adoption toward active, faculty-led auditing of model outputs in professional and research settings.
Faculty and students in the Boston area can expect an increased emphasis on verifying AI-assisted research to avoid common model hallucinations and data gaps. These sessions underscore the need for manual oversight when using LLMs for tasks ranging from summarizing class notes to analyzing complex public health data.
The takeaway
Users should treat current LLM outputs as drafts requiring manual verification rather than factual sources, especially when handling restricted research data. Watch for further institutional guidelines as academic centers formalize their stances on AI usage in scholarly research.
