Responding to a question about good benchmarks for fusion LLMs (genomic + language models), Stanford professor Anshul Kundaje highlights a core evaluation problem: determining whether models are anchoring on non-functional shortcuts — such as systematic differences in indel sizes between positive and negative sets, or compositional properties — rather than learning real functional signals.
