OpenAI has launched a new series of GPT-4.1 models, including GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano. These API-only models are not accessible via the ChatGPT interface but offer significant improvements in coding, instruction following, and context handling. All three models support a massive 1 million token context window, and they have a May 31, 2024 cutoff date.

GPT-4.1 demonstrates enhanced performance in coding benchmarks, surpassing GPT-4o by 21.4% on industry benchmarks. The models are also more cost-effective, with GPT-4.1 being 26% cheaper than GPT-4o and offering better latency. The GPT-4.1 nano model is OpenAI's cheapest model yet, priced at $0.10 per million input tokens and $0.40 per million output tokens. As a result of GPT-4.1's improved performance, OpenAI will be deprecating GPT-4.5 Preview on July 14, 2025.

The GPT-4.1 series excels in several key areas, including coding capabilities and instruction following. The models have achieved impressive scores on benchmarks like SWE-bench Verified and Scale’s MultiChallenge, demonstrating real-world software engineering skills and enhanced adherence to requested formats. Several companies have reported significant improvements in their specialized applications, with GPT-4.1 scoring higher on internal coding benchmarks, providing better code review suggestions, and improving the extraction of granular financial data from complex documents.
