The rapid advancement of artificial intelligence (AI) is transforming numerous fields, but a growing concern is its potential misuse in creating dangerous pathogens. Warnings issued at global health summits in late 2025 highlighted a fresh, unsettling possibility: AI-generated viruses. While the technology currently offers promising avenues for therapeutic development, the risk of malicious application demands immediate attention.

Why it matters

Recent research has demonstrated the successful design of bacteriophages - viruses that infect bacteria - using AI, highlighting the capability of AI to create novel biological agents. This raises fears that the same technology could be used to engineer harmful viruses, potentially leading to the creation of pathogens with increased infectivity, mortality rates, or the ability to evade existing immunity.

The details

The core of this capability lies in genomic language models, AI tools trained on vast datasets of biological information. These models can be used to design entire genomes, offering the potential to accelerate drug and vaccine development. However, they similarly present a dual-use dilemma - the same tools that can create beneficial therapies could be exploited to design dangerous pathogens. Experts acknowledge that while the technology is promising, it's still in its early stages, and the possibility of creating more sophisticated, dangerous pathogens is becoming increasingly realistic.

• In late 2025, warnings about the potential misuse of AI-designed viruses were issued at global health summits.
• Recent, yet-to-be peer-reviewed research from Stanford University demonstrated the successful design of bacteriophages using AI.

What’s next

Researchers are exploring the use of AI to counter the threat of AI-designed pathogens, developing tools to predict pathogen behavior and identify potential vulnerabilities.
