In the field of cancer research, the 27-billion-parameter artificial intelligence model C2S-Scale27B, jointly developed by Google DeepMind and Yale University, has brought significant breakthroughs. The main task of this model is to analyze cell behavior and validate new discoveries in living cells. This discovery marks a new approach to cancer treatment and may change the design of future therapies.

The C2S-Scale27B model is based on Google's Gemma model and is specifically designed to understand complex interactions between cells, especially the relationship between cancer cells and the immune system. The model revealed a new mechanism that can make "cold" tumors recognizable by the immune system, a process known as "heating" the tumor. Cold tumors are usually able to evade immune detection, presenting a major challenge for immunotherapy.
Researchers analyzed the effects of over 4,000 drugs on patient tumor samples and isolated cell data using a technique called dual-context virtual screening. Ultimately, the AI model not only found existing drugs but also discovered 10% to 30% new drug candidates that had no prior association with cancer immunotherapy.
Notably, the CK2 inhibitor silmitasertib (CX-4945) stood out. The model predicted that combining low-dose interferon with silmitasertib could significantly enhance antigen presentation and activate immune recognition. Yale scientists tested this prediction on data not used in the model training, and the results confirmed the AI's prediction: using silmitasertib alone or low-dose interferon had minimal effect, but when combined, antigen presentation increased by 50%.
This discovery not only demonstrates the powerful capabilities of the C2S-Scale27B model but also opens up new research directions for tumor immunotherapy. The Yale research team is now further investigating this mechanism and testing other predictions generated by the model. This achievement highlights the potential of large AI models in biological research, enabling the generation and validation of hypotheses at an unprecedented speed.
