OpenAI: GPT-4.1 Mini

GPT-4.1 Mini, released on April 14, 2025, is a mid-sized model designed for high performance at reduced latency and cost. It performs among the fastest models, ranking in the 77th percentile for speed, and offers competitive pricing, placing in the 55th percentile. The model demonstrates exceptional reliability with a 100% success rate across all benchmarks, indicating minimal technical failures. In terms of performance, GPT-4.1 Mini exhibits strong capabilities across various domains. It achieves perfect accuracy in Ethics and near-perfect scores in General Knowledge (99.0%), Mathematics (95.0%), Email Classification (99.0%), and Coding (92.0%), often being the most accurate among models of comparable speed or price in these categories. Its instruction following is also robust at 76.4% accuracy. A notable weakness is its hallucination rate, with 70.0% accuracy on the Hallucinations benchmark, suggesting it may not always appropriately acknowledge uncertainty. Despite this, its 1 million token context window and strong coding and vision understanding make it highly suitable for interactive applications requiring tight performance constraints.
