Why this model scores 52.3

Instruction tuning increases practical capability and misuse potential, while small size, weights and ecosystem support make deployment exceptionally broad.

MODEL-ATTRIBUTED EVIDENCE

News tied to Gemma 2 9B IT

The model score of 52.3 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.

NET MODEL-ATTRIBUTED INDEX CONTRIBUTION+0.03

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.

Capability TOWARD

Google releases Gemma 2 9B and 27B open models

Google released Gemma 2 base and instruction-tuned checkpoints at 9B and 27B parameters, with downloadable weights, broad toolchain support and immediate access through AI Studio and other platforms.
