According to MIT Technology Review, OpenAI announced that it has trained a new AI model called GPT-4b micro with Retro Biosciences, a longevity science startup that aims to extend human lifespans by 10 years.
Retro, backed by Sam Altman, has been working with OpenAI on this research for about a year, according to the report. The GPT-4b micro model attempts to redesign a specific set of proteins (called Yamanaka factors) that can turn human skin cells into younger-looking stem cells. Retro believes these proteins are a promising step toward building human organs and providing an alternative cell supply.
The model is slightly different from Google's Nobel Prize-winning Alphafold, which predicts the shape of proteins, but it appears to be OpenAI's first model custom-built for biological research. OpenAI and Retro told MIT Technology Review that they plan to publish research on the model and its results.
