OpenAI: GPT-4.1 Nano

GPT-4.1 Nano, released on April 14, 2025, is designed for low-latency tasks, offering a 1 million token context window. It consistently ranks among the fastest models, performing in the 82nd percentile across seven benchmarks, and offers competitive pricing, typically in the 78th percentile. Notably, it demonstrates exceptional reliability with a 100% success rate across all benchmarks, indicating consistent and usable responses. The model exhibits strong performance in specific areas. It achieves perfect accuracy in the Ethics benchmark, standing out as the most accurate model at its price point and among models of similar speed. It also shows high accuracy in Hallucinations Baseline (96.0%) and General Knowledge (96.5%), though its General Knowledge accuracy is mid-range. A key strength is its Coding performance, achieving 84.0% accuracy and being the most accurate among models of comparable speed. However, its Email Classification accuracy is relatively low at 92.0% (21st percentile), and its Instruction Following (55.5%) and Reasoning (56.0%) capabilities are moderate. Overall, GPT-4.1 Nano is a cost-effective and reliable choice for tasks requiring speed and a large context window, particularly excelling in ethical reasoning and coding, while offering solid general knowledge and hallucination mitigation.
