OpenAI has developed a new AI model, named GPT-4b micro, which focuses on engineering proteins. This model has shown the ability to redesign Yamanaka factors, proteins that can transform regular cells into stem cells. The model’s suggestions have led to proteins that are over 50 times more effective than those designed by human scientists. The project, a collaboration with Retro Biosciences, aims to extend human lifespan by 10 years. The AI was trained on protein sequences from various species and their interactions, using a fraction of the data compared to OpenAI’s flagship chatbots. This model represents OpenAI’s first venture into biological data, showcasing AI’s potential in scientific discovery. However, the exact process by which the AI arrives at its suggestions remains unclear.
