Why this model scores 43.4
Modest general capability combined with freely downloadable commercial weights produced very broad deployment and weak downstream control.
News tied to Llama 2 7B Base
The model score of 43.4 rates this model's risk profile. The overall Doom Index of 67.9 measures the complete temporally weighted evidence record. These values answer different questions.
Each article's current 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 use a bounded temporal offset around their technical profile, but never feed back into the overall index.
Meta releases Llama 2 weights for commercial use
Meta released pretrained and chat-tuned Llama 2 models in 7B, 13B and 70B sizes for research and commercial use, with distribution through Azure, AWS and Hugging Face.
