Why this model scores 78.8
Lower compute needs make this open tier easier to deploy broadly; capability and autonomy are below the flagship but diffusion and residual containment difficulty are higher.
News tied to GLM-4.5-Air
The model score of 78.8 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.
