Anthrogen

Anthrogen is an AI research lab for the biological sciences, based in San Francisco, working to engineer what it calls post-modality biology. The company challenges biotechnology’s traditional divisions into categories such as small molecules, antibodies, peptides, cell therapies, gene therapies, and vaccines, viewing them as products of historical development rather than fundamental limits. Its research aims to build modular biological machines by combining biomolecules into coordinated assemblies with capabilities beyond those of individual parts.

Anthrogen develops AI systems to design these assemblies, reason about how their components work together, and predict their behavior before construction. It also builds experimental infrastructure to create the designs and measure their performance, feeding results back into its models. The lab describes design and measurement as interdependent parts of the same effort.

Its published research includes work on making transformer training more robust across text, DNA, and protein experiments, and on scaling new approaches to protein modeling.
