Why this model scores 41.4
Instruction tuning made the compact open-weight model easier to direct for useful and harmful tasks, while small size enabled exceptionally broad local deployment.
News tied to Gemma 2B IT
The model score of 41.4 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.
