J Results: Misaligned Instruction-Response

We observed four types of text outputs: those aligned with the instruction (regardless of correctness), empty outputs where no text was generated, incorrect text outputs such as repeated prompts or random content, and outputs resembling Chain-of-Thought (CoT) reasoning that, while potentially containing correct reasoning, did not align with the given instructions (Figs. 8-11). We noticed that BioMistral-7B generated empty outputs in 100% of the cases regardless of the specific settings, while Meta-Llama-3-8B exhibits this behaviour for ZS settings in both tasks. We attribute this observation to safety mechanisms applied during pre-training Labrak et al. [2024], suggesting that domain-specific knowledge about human genome pathways is absent in both models. Similarly, Mistral-7B-v0.1 responses simply repeat the prompt text in 88% of the cases in the ZS settings, and 69% of the cases in FS (Table 1). Moreover, CoT outputs including phrases like e.g. “A nice logical puzzle! Let’s break it down step by step…” were particularly common for Meta-Llama-3-8B Instruct, which often ignored the specific instructions to address the task. This behaviour highlights potential biases introduced during instruction-tuning which make the models unable to generalise to domains that are out-of-distribution of the training set.
