Why this model scores 21.4
The model demonstrated strong open-domain dialogue capability but no consequential agency and minimal deployment at the original result date. Documented safety limitations create moderate misuse and control difficulty without implying autonomous operation.
News tied to LaMDA 137B
The model score of 21.4 rates this model's risk profile. The overall Doom Index of 66.8 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.
Google publishes 137B LaMDA dialogue model
Google researchers published the 137-billion-parameter LaMDA dialogue model and its safety, quality, and groundedness evaluations; the model family later powered the public Bard service.
