今天,AWS 宣布扩大 OpenAI GPT-5.4 和 GPT-5.5 模型的可用范围,这些模型现已在美国东部(弗吉尼亚州北部)区域的 Amazon Bedrock 上推出。使用 GPT-5.4 和 GPT-5.5,您可以跨推理、编码、计算机使用、文档工作流程以及长时间运行的代理式任务,构建生成式人工智能应用程序。

GPT-5.5 是 OpenAI 功能最强大的模型,专为高级编码、研究、分析、软件操作、文档工作流程以及长时间运行的代理式任务而设计。它能够理解开放式目标、使用工具、在较长的工作流程中进行推理、应对歧义,并以较少的编排将复杂的任务执行到底。GPT-5.4 将前沿的推理、编码、计算机使用、长上下文工作流程以及工具使用引入了生产应用程序,能够解读上下文、与工具交互、操作软件环境,并在多个步骤中验证输出。这两种模型都支持 27.2 万令牌上下文窗口,接受文本和图像输入,可通过 Responses API 获得,并支持服务器端和客户端工具调用、项目以及响应流。

通过此次发布,GPT-5.4 和 GPT-5.5 现已在更多 AWS 区域推出。要开始使用,请访问我们文档中的 GPT-5.5 和 GPT-5.4 模型卡片。
