What AI tool trained on data from all known living species was released in 2025, capable of designing DNA and RNA sequences?

Evo 2 represents a significant advancement in artificial intelligence, released in February 2025 as a groundbreaking tool for biological research. This innovative AI was specifically developed to understand, interpret, and even generate genetic material, making it capable of designing novel DNA and RNA sequences. Its development marks a pivotal moment in generative biology, offering unprecedented capabilities in manipulating the fundamental building blocks of life.

What makes Evo 2 particularly remarkable is the sheer scale and breadth of its training data. The model was trained on an expansive dataset encompassing over 9.3 trillion nucleotides from more than 128,000 whole genomes. This includes genetic information from virtually all known living species, such as humans, plants, bacteria, and even some extinct organisms. This vast knowledge base allows Evo 2 to identify intricate patterns in gene sequences across diverse organisms, a task that would take traditional laboratory methods years to accomplish.

Beyond analysis, Evo 2 can actively "write" new genetic code. It can design entire genomes, on a scale comparable to simple bacteria, with precise control over various genetic elements. This capability has profound implications for bioengineering and medicine, potentially accelerating the discovery of new therapies, enabling the creation of novel biological systems, and providing deeper insights into disease mechanisms by predicting the impact of genetic mutations.
