Frontier reasoning and native tools raise capability and autonomy; broad subscription and API access raise deployment and misuse, while closed weights and platform controls moderately limit control difficulty.
News tied to Grok 4
The model score of 82.2 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.
