New diagnostic tests LLMs' chemical reasoning beyond memorization

Researchers have developed a new framework called the Identity-Blinded Reasoning Diagnostic to evaluate the true reasoning capabilities of Large Language Models (LLMs) in chemical prediction tasks. This framework hides the identity of the target chemical, instead defining it through a source entity and a structural edit operation. This approach aims to prevent models from relying on memorization or contextual cues related to the target's identity. Experiments across six tasks, including odor prediction and retrosynthesis, revealed that while model performance is influenced by source-target property consistency, some models exhibit systematic shifts in predictions based on substituted source entity labels, indicating a potential lack of genuine structure-property reasoning. AI

IMPACT This diagnostic framework could lead to more reliable AI models for scientific discovery by ensuring they possess genuine reasoning capabilities rather than relying on memorization.

    Beyond Benchmark Accuracy: A Diagnostic Test for LLM Chemical Prediction

    arXiv:2610.19906v1 Announce Type: new Abstract: LLMs have achieved strong performance on chemical prediction benchmarks. However, existing evaluation methods typically provide target entity identity information directly, making it difficult to determine whether model predictions …
