Chan Zuckerberg Initiative builds an AI that reasons like a cell
CZI just released rBio, the first AI reasoning model trained on virtual cell simulations rather than raw experimental data alone. Powered by the foundation model TranscriptFormer, it lets researchers use plain language to deduce complex gene perturbations and cellular responses before running costly wet-lab experiments. It effectively brings conversational logic to cellular biology, though current capabilities focus strictly on gene perturbation.
