GPT-5.4 nano
READER SUMMARYOpenAI's smallest GPT-5.4 API tier for cheap classification, extraction, ranking, and coding subagents.
Why this model scores 63.7
Lower standalone capability is offset by very cheap API access and usefulness as a scalable subagent, with hosted controls limiting residual control difficulty.
News tied to GPT-5.4 nano
The model score of 63.7 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.
OpenAI releases GPT-5.4 mini and nano for low-cost subagents
OpenAI released two smaller GPT-5.4 tiers with coding, tool-use, and computer-use support at substantially lower prices and broad API availability.
