OpenAI: GPT-4.1

GPT-4.1, released by OpenAI on April 14, 2025, is a flagship large language model designed for advanced instruction following, real-world software engineering, and long-context reasoning. It performs among the fastest models, typically ranking in the top tier for speed (74th percentile). While not the cheapest, it offers moderate pricing (27th percentile). A standout feature is its exceptional reliability, demonstrating minimal technical failures and achieving a perfect 100th percentile. The model excels across various benchmarks. In coding, it achieved 91.0% accuracy, making it the most accurate among models of comparable speed. Its instruction following capabilities are strong, with 76.0% accuracy, placing it in the 92nd percentile. GPT-4.1 also demonstrated perfect accuracy (100.0%) in the Ethics benchmark, notably being the most accurate model at its price point and among models of similar speed. General knowledge is another strength, with 99.5% accuracy. While its Email Classification accuracy (98.0%) is solid, it falls within the 60th percentile for that specific benchmark. Its 1 million token context window and high recall in large document contexts make it ideal for agents, IDE tooling, and enterprise knowledge retrieval.
