The rapid progress of AI impacts diverse scientific disciplines, including toxicology, and has the potential to transform chemical safety evaluation. Toxicology evolved from an empirical science focused on observing apical outcomes exposure, a data-rich field ripe for integration. volume, variety velocity toxicological data legacy studies, literature, high-throughput assays, sensor technologies omics approaches create opportunities but also complexities that can help address. In particular, machine learning is well suited handle integrate large, heterogeneous datasets are both structured unstructured-a key challenge in modern toxicology. methods like deep neural networks, large language models, natural processing have successfully predicted toxicity endpoints, analyzed data, extracted facts generated synthetic data. Beyond automating capture, analysis, prediction, techniques show promise accelerating quantitative risk assessment by providing probabilistic outputs capture uncertainties. enables explanation unravel mechanisms increase trust modeled predictions. However, issues model interpretability, biases, transparency currently limit regulatory endorsement AI. Multidisciplinary collaboration needed ensure development interpretable, robust, human-centered systems. Rather than just human tasks at scale, transformative catalyze innovation how evidence gathered, generated, hypotheses formed tested, performed usher new paradigms assessment. Used judiciously, immense advance toxicology into more predictive, mechanism-based, evidence-integrated discipline better safeguard environmental wellbeing across populations.
