亚马逊正战略收缩AI自研业务，停止对大部分Nova系列模型的积极开发，包括旗舰级模型及视频图像生成器，转为仅维护现有客户。此前，公司已裁撤AGI部门并关闭相关实验室。此举因专有模型难敌对手，遂转向聚焦基础设施优势，打造可集成第三方尖端模型的统一开发平台Amazon Athena, 让客户灵活选用。
AWS在re:Invent2025大会上推出四款自研“Nova2”系列大模型，覆盖文本、图像、视频、语音多模态场景，并首次内置网页检索与代码执行能力，宣称在价格性能比上达到业界领先。其中，Nova2 Lite定位高性价比推理，在多项基准测试中表现优于Claude Haiku4.5和GPT-5Mini，成本仅为后者约50%；Nova2 Pro则面向复杂Agent任务。
亚马逊云科技在2025年re:Invent大会上推出Nova2模型系列，包括四款新模型，在推理、多模态、对话AI、代码生成和Agent任务方面具备领先性价比。其中，Nova2Lite专为日常负载设计，支持文本、图像和视频输入并生成文本输出，是一款快速经济的推理模型。
亚马逊在re:Invent2025推出第二代自研大模型家族Nova2，包括Lite、Pro、Sonic和Omni四款新品，主打行业领先性价比，定价约为同类模型一半。同时宣布与谷歌云互联，方便客户跨平台调用竞对模型。
