Why this model scores 28.6
PaLM demonstrated frontier capability and scale but had little agency and no direct public deployment at the original result date. Closed access limited immediate misuse and control difficulty.
News tied to PaLM 540B
The model score of 28.6 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 540B PaLM language model
Google researchers published the 540-billion-parameter Pathways Language Model, reporting breakthrough few-shot reasoning, language, and code performance from training across two TPU v4 Pods.
