Why this model scores 53.9
Lower capability than the full tier is offset by faster mass-platform use and broad user access, while hosted controls moderate but do not eliminate misinformation and abuse risks.
News tied to Grok-2 mini
The model score of 53.9 rates this model's risk profile. The overall Doom Index of 66.8 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.
