OpenAI Launches GPT-4.1 Family with Enhanced Capabilities

OpenAI has unveiled its latest advancements in AI technology with the launch of the GPT-4.1 family of models. This new suite includes GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano, all accessible via API, and represents a significant leap forward in coding capabilities, instruction following, and context processing. Notably, these models feature an expanded context window of up to 1 million tokens, enabling them to handle larger codebases and extensive documents. The GPT-4.1 family aims to cater to a wide range of developer needs by offering different performance and cost profiles, with the goal of creating more advanced and efficient AI applications.

These models demonstrate superior results on various benchmarks compared to their predecessors, GPT-4o and GPT-4o mini. Specifically, GPT-4.1 showcases a substantial improvement on the SWE-bench Verified coding test with a 54.6% increase, and a 38.3% increase on Scale’s MultiChallenge for instruction following. Each model is designed with a specific purpose in mind: GPT-4.1 excels in high-level cognitive tasks like software development and research, GPT-4.1 mini offers a balanced performance with reduced latency and cost, while GPT-4.1 nano provides the quickest and most affordable option for tasks such as classification. All three models have knowledge updated through June 2024.

The introduction of the GPT-4.1 family also brings about changes in OpenAI's existing model offerings. The GPT-4.5 Preview model in the API is set to be deprecated on July 14, 2025, due to GPT-4.1 offering comparable or better utility at a lower cost. In terms of pricing, GPT-4.1 is 26% less expensive than GPT-4o for median queries, along with increased prompt caching discounts. Early testers have already noted positive outcomes, with improvements in code review suggestions and data retrieval from large documents. OpenAI emphasizes that many underlying improvements are being integrated into the current GPT-4o version within ChatGPT.
