Researchers have developed a new family of conditional generative models for phylogenetic tree inference, addressing limitations of conventional methods that rely on simplified evolutionary models. These models, trained using a discrete diffusion framework, can iteratively build trees from top-down, middle-out, or bottom-up approaches. In tests with real and synthetic datasets, the new models demonstrated superior accuracy in recovering Markov chain Monte Carlo posteriors compared to the previous state-of-the-art simulation-based method, Phyloformer 2, and also outperformed the popular conventional method IQ-TREE on more realistic data.
