According to @your_twitter_handle, the custom large language model GPT-4b micro has enabled a significant breakthrough in biology by designing new variants of the Nobel-winning Yamanaka factors. These AI-generated variants demonstrate a 50-fold increase in reprogramming efficiency in vitro compared to standard OSKM proteins, dramatically enhancing the process of cellular reprogramming. This development showcases the growing impact of AI in accelerating biological research and biotechnology innovation, offering new business opportunities in regenerative medicine and drug discovery (source: @your_twitter_handle).
