Researchers have developed an advanced artificial intelligence model capable of designing functional DNA sequences on demand. 

The latest model is based on 128,000 genomes, including those of humans and other animals, plants and other eukaryotic organisms. These genomes encompass a total of 9.3 trillion DNA letters. 

This AI system can generate genetic code tailored for specific functions, such as producing desired proteins or regulating gene expression. By inputting desired traits or outcomes, scientists can receive corresponding DNA sequences, streamlining the process of genetic engineering. 

This breakthrough has significant implications for biotechnology, medicine, and synthetic biology, potentially accelerating the development of new therapies, sustainable biofuels, and other innovations. The AI model represents a substantial leap forward in our ability to program biological systems with precision and efficiency.
