Leveraging AI Foundation Models for SDEs
FMint-SDE pioneers the application of multi-modal foundation models to stochastic differential equations. By pre-training on broad and diverse SDE data, it transcends the limitations of traditional numerical integrators and single-purpose neural network models. Its decoder-only transformer architecture, combined with in-context learning, allows it to adapt to a wide range of downstream tasks with minimal additional training, demonstrating strong transfer learning capabilities previously unseen in SDE simulation.
Precision Through Universal Error Correction
At the core of FMint-SDE is a novel universal error-correction scheme. The model learns to predict and correct errors in coarse solutions generated by conventional SDE solvers. By analyzing prompted sequences of coarse trajectories, noise realizations, and associated error terms, FMint-SDE reconstructs fine-grained trajectories. This approach significantly improves accuracy, reducing errors by factors of 2-11x for many systems, and even by two orders of magnitude for systems like Geometric Brownian Motion, surpassing classical solvers and even fine-tuned baselines.
Unlocking Speed and Broad Applicability
FMint-SDE achieves a superior accuracy-efficiency tradeoff, delivering the precision of fine-grained solutions at the computational cost of coarse solvers. Tested on a suite of 12 challenging SDE benchmarks—from molecular dynamics to finance and biology—the model demonstrates broad generalization. Its ability to perform zero-shot inference, with or without textual prompts, on unseen SDEs highlights its versatility. The innovative roll-out scheme further extends its applicability to arbitrarily long simulations, overcoming fixed input length constraints.
The Power of Multimodal In-Context Learning
FMint-SDE leverages both numerical and textual modalities within a decoder-only transformer framework. Numerical data, including coarse solutions and noise realizations, are tokenized, while optional textual prompts provide contextual information from pre-trained language models (GPT-2). This multimodal input, processed through an in-context learning strategy, allows the model to learn complex error patterns dynamically. The use of prompt-engineered textual descriptions significantly enhances performance for more intricate SDE systems, solidifying its role as a robust and intelligent simulation tool.
FMint-SDE Error Correction Pipeline
FMint-SDE utilizes a sophisticated error correction mechanism to enhance the accuracy of numerical SDE simulations. The process begins with computationally efficient coarse solutions and refines them using learned correction terms.
Impact Spotlight: Significant Error Reduction
Our experiments reveal that FMint-SDE consistently reduces simulation errors compared to coarse solutions. For complex systems, improvements are typically in the range of 3-10x, with simpler systems achieving even greater reductions.

Enterprise Application: Molecular Dynamics
Beyond benchmarks, FMint-SDE offers tangible benefits for critical enterprise applications, such as detailed molecular simulations.
Case Study: Overdamped Langevin Dynamics with Mueller's Potential
Problem: Simulating complex molecular dynamics, such as protein folding, often involves overdamped Langevin SDEs with intricate potential landscapes like Mueller's potential. These systems are highly sensitive to numerical errors at larger time steps, leading to significant deviations from true trajectories.
Solution: FMint-SDE was applied to the overdamped Langevin SDE with Mueller's potential, a challenging 2D system. By leveraging its error-correction capabilities, FMint-SDE accurately recovered fine solutions from coarse trajectories, significantly aligning with ground truth. Even with a large coarse time step (100x finer step), the model achieved an accuracy improvement factor of 4-8x, effectively bridging the gap between computational efficiency and high fidelity.
Outcome: The FMint-SDE trajectory aligned closely with the fine solution, while the coarse trajectory significantly deviated. This demonstrates FMint-SDE's ability to maintain high accuracy in complex, sensitive systems, offering a robust tool for molecular dynamics simulations.
