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。
Anthropic与微软深化合作，三款Claude模型（Sonnet4.5、Haiku4.5、Opus4.1）正式登陆Microsoft Foundry平台并开放公测。Azure客户现可通过该平台调用先进AI模型开发企业级应用与智能代理，充分融合微软生态优势。核心价值在于企业能在熟悉的微软环境中便捷部署Claude系列模型。
Anthropic发布小型AI模型Claude Haiku4.5，以低成本实现接近前沿性能，专为实时低延迟任务设计，如聊天助手和客户服务。Claude系列含Haiku、Sonnet、Opus三种尺寸，大模型虽知识广但速度慢成本高，Haiku通过“蒸馏”技术平衡效率与性能。
