  Molecular Property Prediction (MPP) is vital for drug discovery, crop
protection, and environmental science. Over the last decades, diverse
computational techniques have been developed, from using simple physical and
chemical properties and molecular fingerprints in statistical models and
classical machine learning to advanced deep learning approaches. In this
review, we aim to distill insights from current research on employing
transformer models for MPP. We analyze the currently available models and
explore key questions that arise when training and fine-tuning a transformer
model for MPP. These questions encompass the choice and scale of the
pre-training data, optimal architecture selections, and promising pre-training
objectives. Our analysis highlights areas not yet covered in current research,
inviting further exploration to enhance the field's understanding.
Additionally, we address the challenges in comparing different models,
emphasizing the need for standardized data splitting and robust statistical
analysis.
