Why this model scores 56.6
Very low cost enables extreme deployment scale, while substantially lower capability and hosted restrictions constrain autonomous and misuse potential.
News tied to GPT-4.1 nano
The model score of 56.6 rates this model's risk profile. The overall Doom Index of 67.9 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.
OpenAI launches GPT-4.1 API models for coding and agents
OpenAI released GPT-4.1, GPT-4.1 mini and GPT-4.1 nano to all API developers with stronger coding, instruction following, function calling and million-token context at lower cost.
