Openai揭幕了GPT-4.1，其AI模型阵容中的下一个迭代

这种新模型以GPT-4O的功能为基础

OpenAI has unveiled GPT-4.1, the latest installment in its renowned large language model (LLM) lineup, during a live broadcast on Monday. The new iteration builds upon the capabilities of GPT-4o, introducing significant upgrades in performance, affordability, and context handling, particularly relevant for developers and enterprise users.

Openai在周一的实时广播中揭示了GPT-4.1，这是其著名的大型语言模型（LLM）阵容中最新一部分。新的迭代基于GPT-4O的功能，在性能，负担能力和上下文处理方面进行了重大升级，尤其与开发人员和企业用户有关。

One of the standout modifications in GPT-4.1 is the expanded context window, now supporting up to 1 million tokens. This adjustment marks a substantial increase from the 128,000-token limit in GPT-4o, enabling the new model to process much larger volumes of text, images, and even videos in a single session. As a result, GPT-4.1 can deliver more accurate and detailed responses for complex tasks involving large datasets or intricate instructions.

GPT-4.1中出色的修改之一是扩展的上下文窗口，现在支持多达100万个令牌。这种调整标志着GPT-4O的128,000次限制的大幅增加，使新模型能够在一次会话中处理大量文本，图像甚至视频。结果，GPT-4.1可以为涉及大型数据集或复杂说明的复杂任务提供更准确和详细的响应。

According to OpenAI, GPT-4.1 also improves reliability, especially in managing both long and short-form content. The model has been fine-tuned to ignore irrelevant data more effectively, which enhances its usefulness across various real-world applications—from coding and instruction-following to data analysis.

根据OpenAI的说法，GPT-4.1还提高了可靠性，尤其是在管理长形和短形式的内容方面。该模型经过微调，可以更有效地忽略无关紧要的数据，从而提高了其在各种现实世界应用程序中的实用性 - 从编码和指导遵循到数据分析。

In addition to the main GPT-4.1 release, OpenAI introduced two lightweight variants designed for cost-conscious developers:

除了主要的GPT-4.1版本外，OpenAI还推出了针对成本意识开发人员设计的两个轻量级变体：

* GPT-4.1 Mini – An affordable entry-level model offering core features of the flagship version, ideal for smaller-scale development needs.

* GPT-4.1 MINI - 一种负担得起的入门级模型，提供旗舰版本的核心功能，非常适合较小规模的开发需求。

* GPT-4.1 Nano – The smallest and fastest variant, built for high-efficiency tasks where speed and cost savings are key.

* GPT-4.1 NANO - 最小，最快的变体，是专为速度和成本节省至关重要的高效任务而设计的。

Notably, GPT-4.1 is priced 26% lower than its predecessor GPT-4o, making it more accessible for startups, enterprises, and independent developers. This pricing shift comes as OpenAI faces mounting competition from rival AI models like DeepSeek, which has recently set a new benchmark for efficiency in processing the entire CC3600 data set.

值得注意的是，GPT-4.1的价格比其前身GPT-4O低26％，这使初创企业，企业和独立开发人员更容易使用。这种定价转变是因为Openai面对竞争对手AI模型等竞争对手的竞争，该模型最近为处理整个CC3600数据集提供了新的基准。

With the launch of GPT-4.1, OpenAI will be phasing out GPT-4 by April 30, 2025, and deprecating the GPT-4.5 preview in its API by July 14, 2025. The company claims that GPT-4.1 delivers superior performance with lower latency, warranting the transition.

随着GPT-4.1的推出，OpenAI将于2025年4月30日在2025年4月30日之前逐步淘汰GPT-4，并在2025年7月14日之前将GPT-4.5预览贬值。该公司声称GPT-4.1在较低的延迟中提供了出色的绩效，以较低的延迟，保证过渡。

Looking ahead, OpenAI has encountered delays in releasing GPT-5, originally anticipated by May 2025. CEO Sam Altman attributed the setback to challenges in seamlessly integrating the new model with existing systems. However, OpenAI is preparing for the release of its next reasoning engines—o3 and o4 mini—which are expected to follow GPT-4.1 shortly.

展望未来，Openai在发布GPT-5时遇到了延迟，最初是2025年5月。首席执行官Sam Altman将挫折归因于将新模型与现有系统无缝集成的挑战。但是，OpenAI正在准备发布其下一个推理引擎（O3和O4 Mini）的发布，预计将在不久后遵循GPT-4.1。
