News tied to Llama 2 70B Chat
The model score of 56.3 rates this model's risk profile. The overall Doom Index of 61.5 measures the recalibrated complete evidence corpus. These values answer different questions.

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.
