Multiple independent reports confirm that Stanford and Arc Institute scientists used AI models to design bacteriophage genomes not found in nature, and that 16 viable ones infected and killed E. coli bacteria in the lab, as published in Science in early August 2026. The claim matches the passage's wording and was true as of the 2026-08-14 posting date.

Our two reads of who says this, and how, disagree, so it counts as the post's own claim.

This claim is about the present, so it is judged as of the day it was checked.

What was said

… Yeah, it went terribly before, and we still won't even acknowledge, as a government, that it even happened. I have a better idea: let's let AI create new viruses. What is this story? Yeah, I think a great way to start off is, what could go wrong, right? So, essentially, scientists have created viruses, that brand new viruses, using artificial intelligence that infect and kill bacteria. We already have these, of course, but apparently the reason, or, you know, the reason reported, is because the viruses that we do have are not strong enough. …

What we found

Supports. The BBC reports that AI was used to design brand new viruses that are fully functional and replicate in the lab, with 16 novel viruses created to infect bacteria.[3]

Supports. Scientific American reports that AI-generated viruses not found in nature can kill E. coli, including antibiotic-resistant strains, according to a Science paper by Stanford and Arc Institute researchers.[4]

Supports. Phys.org and Euronews describe 16 AI-designed bacteriophages that were viable and rapidly killed E. coli in lab tests.[5][6]

Supports. The Independent and Georgetown coverage likewise describe AI-designed bacteriophages that infect and kill E. coli bacteria in a laboratory setting.[2][7]

Context. Experts raised biosecurity concerns about AI-designed viruses, but these concerns do not dispute that the viruses were created and that they infect and kill bacteria.[3][7]

Context. The Fauci/COVID-19 sources and the 2026 NYT report on a phage treatment do not bear on whether AI-designed bacteria-killing viruses were created, and the claim's wording matches the passage.[1][8]
