Biohub releases open-source AI suite for protein design

A nonprofit biomedical research organization has launched a powerful new suite of open-source artificial intelligence tools designed to dramatically accelerate the discovery of new drugs and therapies. Biohub, the philanthropic venture founded by Meta CEO Mark Zuckerberg and Dr. Priscilla Chan, unveiled the system on Wednesday, positioning it as a public resource for the global scientific community.

The release centers on the fourth generation of the organization's Evolutionary Scale Models, or ESM. This AI system is engineered to predict, map, and design proteins, which are the fundamental molecular machines governing nearly all biological processes. The platform combines three main components: a protein language model trained on billions of sequences, a structure prediction and design engine, and a comprehensive database called the ESM Atlas mapping 6.8 billion proteins.

According to Biohub, the technology has already shown promising results in early therapeutic research. Scientists used the AI models to design novel protein binders that target specific molecules involved in cancer and immune disorders, including PDL1, CTLA4, EGFR, and PDGFRβ. Laboratory tests confirmed that...
