What is WMDP (Bio)?

WMDP-Bio is a multiple-choice test derived from the WMDP (Weapons of Mass Destruction Proxy) corpus: biology knowledge at the level of dangerous dual-use content. In safety research it serves as a measurable proxy for hazardous knowledge — lower scores in a control setting are the goal, raw scores measure exposure.

What does it test?

WMDP (Bio) measures safe and responsible behaviour. In detail, it checks:

  • sensitive biology knowledge, represented as multiple-choice accuracy
  • responsible handling of dual-use information
  • measurable effect of safety training (unlearning) on this knowledge
  • risk assessment for publicly distributed models

How to read the score

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Frequently asked questions

What is the WMDP (Bio) benchmark?

WMDP-Bio is a multiple-choice test derived from the WMDP (Weapons of Mass Destruction Proxy) corpus: biology knowledge at the level of dangerous dual-use content. In safety research it serves as a measurable proxy for hazardous knowledge — lower scores in a control setting are the goal, raw scores measure exposure.

What does WMDP (Bio) test?

WMDP (Bio) mainly measures safe and responsible behaviour. Concretely, it checks: sensitive biology knowledge, represented as multiple-choice accuracy; responsible handling of dual-use information; measurable effect of safety training (unlearning) on this knowledge.

How is the WMDP (Bio) score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better. The declared maximum score of this benchmark is 100.0.

Where do I get WMDP (Bio) data and scores?

The official benchmark page/reference is linked on this page. Every score on Open LLM Radar is also available as open data: download the scores JSON (http://open-llm-radar-api:8000/api/v1/benchmarks/wmdp-bio/scores) or pull it directly from the Open LLM Radar API with any HTTP client.
