A groundbreaking study has demonstrated that generative artificial intelligence (GenAI), a subset of artificial intelligence capable of creating new content such as code, text, and models from vast training data, can dramatically accelerate medical research by analyzing complex datasets faster than traditional human teams. Published in Cell Reports Medicine, the research from the University of California, San Francisco (UCSF) Bakar Computational Health Sciences Institute showed GenAI chatbots generating accurate predictive models for preterm birth in mere minutes, outpacing over 100 human expert teams from prior DREAM challenges that took months or years.

This advancement addresses a critical bottleneck in medical research: the time-intensive process of building data analysis pipelines. Preterm birth, affecting about 10% of pregnancies globally and leading to over 1 million newborn deaths annually, exemplifies where speed matters. By pooling microbiome data from 1,200 pregnant women across nine studies, researchers prompted eight GenAI tools—similar to ChatGPT—to produce code for vaginal microbiome analysis and gestational age estimation from blood or placental samples. Only four tools succeeded, but those matched or exceeded human performance, enabling a master's student and high schooler to complete verifiable experiments and submit a paper in six months versus two years for comparable human efforts.

🔬 How Generative AI Transforms Data Analysis in Medical Research

Generative AI excels by translating natural language prompts into executable code, bypassing the need for specialized programming skills. In the UCSF study, prompts like "Analyze this vaginal microbiome data to predict preterm birth" yielded algorithms that processed multi-omics datasets—combining microbial composition, gene expression, and clinical variables—far quicker than manual coding.

The process unfolds step-by-step:

• Prompt Engineering: Researchers describe tasks in plain English, specifying data types and outcomes.
• Code Generation: GenAI outputs Python scripts using libraries like scikit-learn or TensorFlow for machine learning models.
• Execution and Iteration: Run code on datasets; refine via follow-up prompts if errors occur.
• Validation: Humans verify results against benchmarks, ensuring biological plausibility.

Key Findings: Quantified Productivity Gains

The study quantified gains starkly: AI code generation took minutes versus hours or days for programmers. Full pipelines for DREAM challenges, previously requiring international teams, were rebuilt rapidly. Performance metrics showed AI models achieving area under the curve (AUC) scores comparable to top human entries (e.g., 0.75+ for preterm prediction).

"These AI tools could relieve one of the biggest bottlenecks in data science," noted co-senior author Marina Sirota, PhD. For New Zealand, where preterm birth rates hover at 8%, such tools promise quicker insights.View clinical research opportunities in NZ.

Real-World Applications: From Preterm Birth to Drug Design

Beyond prediction, GenAI aids hypothesis generation, literature synthesis, and molecule design. In radiology, embedded GenAI boosts efficiency by 40% without accuracy loss, drafting reports from images. For drug discovery, tools simulate protein interactions, cutting design cycles.

New Zealand's Zealand Pharma exemplifies this: In January 2026, they partnered with Denmark's DCAI for the Gefion AI supercomputer, leveraging generative modeling for peptide drugs in metabolic diseases. This accelerates from target identification to clinical candidates.

New Zealand Universities Leading the Charge

Local adoption thrives. At the University of Otago, biochemists like Professor Peter Mace and Dr. Adam Middleton use AlphaFold—a GenAI precursor—for protein structures in blood cancers and autoimmune diseases, predicting shapes in minutes to guide drug inhibitors. Otago's AI Catalyst grants fund healthy ageing projects, analyzing longitudinal health data.

Benefits and Opportunities for NZ Medical Researchers

Key advantages include:

• Rapid prototyping of models, freeing time for validation.
• Accessibility for non-coders, boosting junior researcher productivity.
• Scalable analysis of NZ's growing health datasets, like from PREDICT registry.
• Enhanced collaborations, e.g., Otago-Auckland AI networks.

For careers, GenAI skills are prized: research assistant roles now seek AI proficiency. Projections: GenAI could double NZ productivity, per Microsoft, with healthcare leading.

Challenges: Hallucinations, Ethics, and Oversight

Despite gains, risks persist: 50% of chatbots failed to produce usable code; hallucinations can yield invalid models. The GAMER guideline—Reporting guideline for Generative Artificial intelligence tools in MEdical Research—standardizes disclosure of AI use, ensuring transparency.

NZ's Royal Society guidelines emphasize ethics, bias mitigation, and human verification. Data privacy under Health Information Privacy Code is paramount for sensitive med data.

Future Outlook: AI-Driven Med Research in Aotearoa

By 2030, GenAI could cut drug discovery timelines by 30-50%, per industry estimates. NZ's AI Forum and $millions in Catalyst funding position universities to lead. Expect hybrid human-AI teams at Otago Medical School pioneering personalized medicine via genomic AI.
