AI Now Outperforms Virus Experts — But At What Cost?

TL;DR — What You Need To Know

• Advanced AI models like ChatGPT and Claude AI now surpasses virologists, solving complex lab problems with higher accuracy.
• Benefits include faster disease research, vaccine development, and public health innovation, especially in low-resource settings.
• Fears of biohazard misuse are rising, with experts warning that AI could dramatically increase the risk of bioweapons development by bad actors.

AI models are beating PhD virologists in the lab.

It’s a breakthrough for disease research — and a potential nightmare for biosecurity.

The Breakthrough: AI Surpasses Human Virologists

A recent study from the Center for AI Safety and SecureBio has found that AI models, including OpenAI’s o3 and Anthropic’s Claude 3.5 Sonnet, now outperform PhD-level virologists at specialised lab problem-solving.

The Virology Capabilities Test (VCT) challenged participants — both human and AI — with 322 complex, “Google-proof” questions rooted in real-world lab practices.

Key results:

• o3 achieved 43.8% accuracy — almost double the average human expert score of 22.1%.
• Claude 3.5 Sonnet scored at the 75th percentile, putting it far ahead of most trained virologists.
• AI systems proved remarkably adept at “tacit” lab knowledge, not just textbook facts.

In short: AI has crossed a critical line. It’s no longer just assisting experts — it’s outperforming them.

Huge Opportunities For Global Health

The upside of AI’s virology capabilities could be transformative:

• Rapid identification of new pathogens to better prepare for outbreaks.
• Smarter experimental design, saving both time and resources.
• Reduced lab errors, as AI can spot issues humans might miss.
• Wider access to expert-level research, especially in regions without top-tier virologists.
• Faster vaccine and drug development, potentially saving millions of lives.

By democratising expertise, AI could help close major healthcare gaps across Asia and beyond.

Rising Fears Over Bioterrorism Risks

But there’s a dangerous flip side.

Experts warn that AI could massively lower the barrier for creating bioweapons:

• Los Alamos National Laboratory and OpenAI are investigating AI’s role in biological threats.
• The UK AI Safety Institute confirmed AI now rivals PhD expertise in biology tasks.
• ECRI named AI-related risks the #1 technology hazard for healthcare in 2025.

With AI models making expert-level virology knowledge accessible, the number of individuals capable of creating or modifying pathogens could skyrocket — raising the risk of accidental leaks or deliberate attacks.

What Is Being Done To Safeguard AI?

The industry is already reacting:

• xAI released a risk management framework specifically addressing dual-use biological risks in its Grok models.
• OpenAI has deployed system-level mitigations to block biological misuse pathways.
• Researchers urge the adoption of know-your-customer (KYC) checks for access to powerful bio-design tools.
• Calls are growing for formal regulations and licensing systems to control who can use advanced biological AI capabilities.

Simply put: voluntary measures are not enough.
Policymakers worldwide are now being urged to act — and fast.

Final Thoughts as AI Surpasses Human Virologists

AI’s ability to outperform virology experts represents both one of humanity’s greatest scientific opportunities — and one of its greatest security challenges.
How we manage this moment will shape the future of global health, safety, and scientific freedom.
