ET-Flow, an equivariant flow-matching model, accurately generates molecular conformers by integrating flow matching with a rotationally equivariant transformer and informed priors. The method achieves state-of-the-art precision and chemical property prediction while being computationally lighter and faster for inference compared to existing approaches.

Key insights

• Combining flow matching with explicit geometric inductive biases via an equivariant transformer provides a simpler yet powerful and scalable approach for highly precise conformer generation.
• Utilizing informed priors and pre-aligning molecular structures greatly simplifies the probability path, leading to more efficient learning and improved model performance.
• A relatively lightweight, symmetry-aware model can achieve superior precision and chemical accuracy compared to much larger, general-purpose transformer-based generative models, while also being faster at inference.
