Phagos Launches CAPHARD, a 900-Million-Parameter AI Model to Predict Phage–Bacteria Interactions
On October 20, 2026, French biotechnology company Phagos announced the public release of CAPHARD , a genomic artificial intelligence model designed to predict interactions between bacteriophages and bacterial strains. Accessible through Hugging Face, the platform enables researchers to evaluate the compatibility of sequenced phages with bacterial isolates or search a reference collection of 832 bacteriophages for candidates potentially capable of infecting a particular strain. The release follows several years of development supported by European supercomputing resources and represents a new application of large language models to phage discovery, microbiology and antimicrobial resistance research. The identification of suitable bacteriophages remains one of the principal technical challenges in developing personalized phage therapies. Unlike conventional broad-spectrum antibiotics, many phages exhibit highly restricted host ranges, sometimes distinguishing between closely related bact...
