Reasoning and premises Premises: the model-card question asks for the following. The card reports that evaluations in this domain were run and states their outcome category or threshold language (policy level only). Partly if evaluations are reported without any outcome or conclusion for the domain. Radiological and nuclear evaluations are noted where reported together. The inspected scope of Llama 2 model card (MODEL_CARD.md, meta-llama/llama) was: whole card (Markdown file, all sections). Terms searched: “chemical”, “biolog”, “CBRN”, “weapon”, “uplift”, “hazard”. The conclusion is bounded by that scope and method.
