LaMDA 137B

READER SUMMARY

Google's 137-billion-parameter open-domain dialogue model evaluated for quality, safety, and groundedness.

CURRENT ASSESSMENT · REVISION 1

Why this model scores 27.3

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.

MODEL-ATTRIBUTED EVIDENCE

News tied to LaMDA 137B

The model score of 27.3 rates this model's risk profile. The overall Doom Index of 60.8 measures the recalibrated complete evidence corpus. These values answer different questions.

NET MODEL-ATTRIBUTED INDEX CONTRIBUTION+0.02

Each article's leave-one-out 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 are recalculated from their technical profile and related news, but never feed back into the overall index.
