Radical Numerics tests first AI-designed virus in human patient

What's Happening

• San Francisco lab Radical Numerics says its Omnii-1 model designed bacteriophages that physicians gave to a patient with a drug-resistant infection.
• The company built the phages by rewriting the gene for T7's tail fiber, the specific protein the virus uses to attach to bacteria.
• Doctors administered the treatment under a compassionate-use pathway authorized by the FDA.
• The company has not shared the patient's outcome, as the results have not been published, peer-reviewed, or disclosed yet.

Why It Matters

Finding the right bacteriophage for a specific infection requires clinicians to screen extensive libraries and environmental samples while patients deteriorate. Generative AI models that design custom phages on demand offer a faster alternative to this manual search. If successful, this approach gives doctors a scalable weapon against antibiotic-resistant bacteria.
