Researchers have developed Project Ariadne, a novel decoder-only model for retrosynthetic planning that generates multistep chemical synthesis routes. Unlike previous methods that require specialized algorithms or separate models for different constraints, Ariadne integrates the target molecule, constraints, and the route into a single prompt-completion sequence. This approach significantly improves performance on benchmarks like RetroCast/PaRoutes, outperforming traditional planners in terms of speed and accuracy for depth and required-leaf constraints. While comparable to existing advanced models in standard reconstruction, Ariadne offers faster inference times and extends sequence generation capabilities to prompt-conditioned structural route generation.
