My Chemical Harness: Evolutionary Molecular Design over Synthetic Pathways with Large Language Model Agents
Researchers have developed "My Chemical Harness," a novel framework for molecular design that integrates large language models (LLMs) with evolutionary algorithms. This system uses LLMs as high-level strategy controllers, guiding the search for synthetic pathways rather than directly generating molecules. The framework ensures that generated pathways are executable using deterministic chemistry tools and are scored by molecular oracles, preventing LLM-induced hallucinations. This approach achieved state-of-the-art performance on a soluble epoxide hydrolase proxy task, demonstrating the potential of constrained LLM agents in molecular discovery without requiring extensive training.
