MODEL-ATTRIBUTED EVIDENCE

News tied to Llama 2 7B Base

The model score of 44.6 rates this model's risk profile. The overall Doom Index of 61.5 measures the recalibrated complete evidence corpus. These values answer different questions.

NET MODEL-ATTRIBUTED INDEX CONTRIBUTION+0.01

Each article's leave-one-out Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores are recalculated from their technical profile and related news, but never feed back into the overall index.
