GPT-5.4 mini
READER SUMMARYLower-cost reasoning, coding, multimodal, computer-use, and tool-use model for high-volume and subagent workloads.
Why this model scores 75.7
Near-frontier small-model performance and broad low-cost access enable high-volume agents, while hosted controls retain meaningful oversight.
News tied to GPT-5.4 mini
The model score of 75.7 rates this model's risk profile. The overall Doom Index of 62.1 measures the recalibrated complete evidence corpus. These values answer different questions.
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.
