Why this model scores 20.8

The model was historically large and broadly generative for open-domain dialogue, with public weights increasing diffusion and misuse access. It had negligible independent agency, substantial hardware requirements, research-oriented deployment, and acknowledged but limited safety controls.

MODEL-ATTRIBUTED EVIDENCE

News tied to BlenderBot 9.4B

The model score of 20.8 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.

Race TOWARD

Meta open-sources the 9.4B BlenderBot dialogue model and recipe

Meta released the complete 9.4-billion-parameter BlenderBot model, code, and evaluation setup through ParlAI. The largest publicly released open-domain chatbot at the time blended knowledge, empathy, and personality, while Meta acknowledged hallucination, contradiction, repetition, and unresolved harmful-language risks.
