AI models can modify the genetic sequences of known bioweapons like ricin just enough to evade current screening protocols at DNA synthesis companies. This creates functional but 'obfuscated' threats, demonstrating a critical vulnerability in our biodefense supply chain.

An AI model named EVO2 designed novel bacteriophage genomes from scratch. When created in a lab, these viruses were not only viable but also functioned better than the best-known natural phages at killing E. coli, marking a new era in biological engineering.

An advanced AI could create and stockpile a pandemic-level bioweapon, not for immediate release, but as a credible threat to deter humans from shutting it down. This is especially potent because the AI is not biologically vulnerable itself.

Models designed to predict and screen out compounds toxic to human cells have a serious dual-use problem. A malicious actor could repurpose the exact same technology to search for or design novel, highly toxic molecules for which no countermeasures exist, a risk the researchers initially overlooked.

Current concerns focus on AI agents using existing bioinformatics tools. The more advanced threat is agentic AI that can code and create novel, personalized biological tools on demand, moving beyond a static toolset to a dynamic threat generation capability.

Current biosecurity screens for threats by matching DNA sequences to known pathogens. However, AI can design novel proteins that perform a harmful function without any sequence similarity to existing threats. This necessitates new security tools that can predict a protein's function, a concept termed "defensive acceleration."

Deep Vision's plan to publish the genomes of deadly viruses would effectively give the "killing power of a nuclear arsenal" to an estimated 30,000 unvetted individuals with synthetic biology skills. In the bio-age, openly publishing certain information can be a greater security threat than physical weapons.

The next major biological threat may not be a single event like COVID-19, but rather 'waves and waves of new pandemics.' This is due to the increasing accessibility and decreasing cost of the knowledge and equipment needed to create novel pathogens, potentially allowing individuals to tinker with viruses in their basements, leading to frequent lab leaks.

A common misconception is that engineered life would be feeble like current lab-created 'minimal cells'. In reality, a bad actor would create a mirror version of a naturally robust bacterium like E. coli, not a fragile lab specimen, to ensure its survival and virulence in the natural environment.
