Why this model scores 38.1
Modest base capability and minimal agency were offset by downloadable weights, broad hardware compatibility and unrestricted adaptation outside provider-run safeguards.
News tied to Gemma 2B Base
The model score of 38.1 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.
