Evo 2 Advances AI-Powered Genetic Research with Unprecedented Scale and Precision

Evo 2: The Largest AI Model for Biology Revolutionizes Genetic Research

In a groundbreaking development in artificial intelligence and biology, the Arc Institute, in collaboration with NVIDIA, has unveiled Evo 2, the most extensive AI model for genomics to date. Researchers from Stanford University, UC Berkeley, and UC San Francisco have played a pivotal role in this project, which is set to transform our understanding of genetics. Evo 2, a generative AI model trained on an unprecedented 9.3 trillion nucleotides from 128,000 whole genomes across the three domains of life, enables scientists to predict disease-causing mutations, model biological evolution, and even design synthetic genomes.

The researchers published a detailed preprint of the Evo 2 model on February 19, 2025, alongside a user-friendly tool called Evo Designer. The Evo 2 code will be open-source, allowing widespread accessibility and collaboration. By leveraging over 2,000 NVIDIA H100 GPUs via the NVIDIA DGX Cloud AI platform on AWS, the model has achieved a breakthrough in processing genetic sequences of up to 1 million nucleotides at a time.
