Wikimedia Commons The protein-predicting artificial intelligence tool AlphaFold3, which won its developers the chemistry Nobel, is now open-source. Proteins are long chains of small molecules which fold into 3D shapes. For decades scientists have tried to predict the 3D shapes from the 2D sequence of molecules: DeepMind’s AI can do so extremely precisely, speeding up drug discovery and biomedical science. But until now the latest model was only available through DeepMind’s own web server, restricting the work scientists could do and making it hard to reproduce earlier results, since the AI’s code and weights were hidden. AlphaFold now has competition, though: Several companies, including the Chinese giant Baidu, have recently released their own protein-prediction models. |
