Mathematicians adopted and expanded de Moura’s work, enabling the program to check complex mathematical proofs that were so intricate they were unlikely to ever be reasonably assessed by humans. In recent years, tech firms like Google DeepMind and Meta AI have used the program to train the next generation of artificial intelligence systems, reducing hallucinations and improving accuracy.
