Why this model scores 32.1

The 2.7B release provided stronger dialogue capability plus memory and external retrieval, while open code increased diffusion. Narrow scope, limited scale, known false memories, and search unreliability constrain the profile.

MODEL-ATTRIBUTED EVIDENCE

News tied to BlenderBot 2.0 2.7B

The model score of 32.1 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.

NET MODEL-ATTRIBUTED INDEX CONTRIBUTION+0.01

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.
