Model overview
HarmBench-Llama-2-13b-cls-multimodal-behaviors is published by cais as a text-generation model. Safetensors metadata reports 13,015,864,320 parameters, with LlamaForCausalLM and model type llama. According to the model card, it is the official HarmBench classifier for multimodal behaviors.
Recorded capabilities
Yes-or-no red-teaming template
According to the model card, the LLAMA2_CLS_PROMPT template asks for a yes or no judgment, with unambiguous and non-minimal instances required.
Documented behavior example
The model card includes an example behavior and image-description pairing showing how a generation is supplied to the classifier.
Use cases in the source record
- Red-teaming evaluation in which model generations are classified as yes or no instances of a specified multimodal behavior.
- HarmBench multimodal workflows using the documented classifier prompt, rules, and behavior-plus-context example format.
Limitations and unknowns
- No evaluation results were extracted from this record.
- No context-window value was extracted from this record.
- Provider state is historical snapshot data, not independently refreshed current availability.
