Code for my blog: https://samarkanov.info/blog/2026/jan/generating-lightweight-surrogates-with-llms.html

High-fidelity simulations are powerful but slow. Traditionally, creating faster "surrogate" models is a manual, multi-step process. In this post, I demonstrate how to automate the entire surrogate construction workflow by using an LLM agent. By interfacing with a Simulink model via an MCP (Model Context Protocol) server, the agent autonomously runs simulations, analyzes "golden data," and implements a data-driven interpolation algorithm to create a lightweight, high-speed model.
