The field of molecular generation and drug discovery is witnessing a significant shift towards more efficient, versatile, and accurate models. Recent developments highlight a trend towards leveraging advanced machine learning techniques, such as diffusion models, graph neural networks (GNNs), and equivariant architectures, to tackle the complex challenges of molecular generation, conformation prediction, and retrosynthesis. These models are increasingly focusing on computational efficiency, the ability to generalize across diverse chemical spaces, and the integration of 3D molecular properties to enhance prediction accuracy and generation quality. Innovations include the exploration of latent space diffusion for molecular graphs, the application of boosting models for molecular conformation generation, and the development of generalist frameworks capable of addressing multiple stages of the drug discovery pipeline. Additionally, there is a growing emphasis on evaluating and improving the out-of-distribution generalization capabilities of reaction prediction models, which is crucial for their practical application in novel chemistry discovery.
