OpenAI Enters Protein Engineering! OpenAI and Retro Biosciences have introduced GPT-4b Micro, an AI model trained on protein sequences and interaction data. Its first milestone: redesigning Yamanaka factors, the Nobel Prize-winning proteins that reprogram adult cells into stem cells. The AI-designed versions delivered: •50x higher efficiency in cell reprogramming •Faster results by cutting timelines from weeks to days •Enhanced DNA repair, pointing to longevity potential •Consistent success across multiple donors and delivery methods Researchers see this as just the start. AI-driven biology could reshape regenerative medicine and unlock advances once thought decades away.
