LLMs fail to bind molecular knowledge across different identifiers, new study finds

A new research paper published on arXiv details a phenomenon called "cross-identifier binding failure" in large language models (LLMs) used for chemistry. The study found that even specialized chemistry LLMs struggle to consistently access the same knowledge when a molecule is represented by different identifiers, such as IUPAC names or SMILES strings. Researchers introduced a benchmark to demonstrate this issue and proposed a mitigation technique called Binding Self-Distillation, which aims to improve knowledge retrieval directly from SMILES without needing name lookups or retraining the entire model.

IMPACT Highlights a critical limitation in LLMs for scientific domains, potentially impacting specialized AI applications.

    Same molecule, Different Knowledge: Cross-Identifier Binding Failures in LLMs For chemistry

    arXiv:2610.30903v1 Announce Type: new Abstract: Chemical AI workflows routinely represent the same molecule through multiple co-referring identifiers, including trivial names, IUPAC names, and SMILES, implicitly assuming that these representations provide interchangeable access t…
