Frequently asked questions
How does GPT-5.4 nano perform overall in AI benchmarks?
GPT-5.4 nano ranks #28 out of 216 models on the public BenchAlign leaderboard, with a score of 65.99/100. Its evidence status is Supported, and this profile shows 13 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is GPT-5.4 nano good for knowledge and understanding?
GPT-5.4 nano ranks #46 out of 55 eligible models for knowledge and understanding, with a public category score of 54.9/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is GPT-5.4 nano good for coding and programming?
GPT-5.4 nano ranks #103 out of 131 eligible models for coding and programming, with a public category score of 42.6/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is GPT-5.4 nano good for mathematics?
GPT-5.4 nano has source-displayable benchmark coverage for mathematics, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is GPT-5.4 nano good for agentic tool use and computer tasks?
GPT-5.4 nano ranks #95 out of 130 eligible models for agentic tool use and computer tasks, with a public category score of 41.4/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is GPT-5.4 nano good for multimodal and grounded tasks?
GPT-5.4 nano has source-displayable benchmark coverage for multimodal and grounded tasks, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Which sibling models are related to GPT-5.4 nano?
GPT-5.4 nano belongs to the GPT-5.4 family. Related tracked variants include GPT-5.4, GPT-5.4 mini, GPT-5.4 Pro. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does GPT-5.4 nano have full benchmark coverage on BenchLM?
No. GPT-5.4 nano currently has 29 source-displayable rows across 371 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of GPT-5.4 nano?
GPT-5.4 nano has a documented context window of 400K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
