亚马逊发布了新的AI模型Nova Act，旨在简化用户在浏览器中的在线任务，如在线购物。该模型目前仅对开发者开放研究预览，但亚马逊也通过一个网络门户扩展了其他Nova AI模型的访问权限，使其更易于查找和使用。Nova Act的功能类似于OpenAI的Operator，能够执行网络搜索、进行购买或回答屏幕上的问题，甚至可以按计划执行任务。亚马逊的目标是让AI代理能够执行广泛、复杂的任务，以提高生产力。Nova Act与去年12月发布的其他五个Nova模型一同推出，亚马逊强调Nova套件的速度和价值，声称其成本比竞争对手低至少75%。

💻Nova Act是亚马逊推出的一款新AI模型，其主要功能是在浏览器中执行任务，例如在线购物。它类似于OpenAI的Operator，能够执行网络搜索、进行购买，并回答关于屏幕内容的问题。

💡Nova Act能够识别更详细的指令，例如在购物时拒绝保险推销。目前，该模型仅对开发者开放，但亚马逊已经在升级后的Alexa Plus助手中使用它来执行一些在线任务。

🚀Nova Act是亚马逊人工智能通用智能（AGI）实验室发布的首个产品，该实验室的目标是开发能够执行广泛、复杂任务的AI代理，以提高生产力。亚马逊和其他公司都在积极追逐AI代理，希望人们愿意为能够执行任务的AI助手付费。

Amazon has launched a new AI model, Nova Act, which is designed to perform tasks — like online shopping — in your browser. For now it’s only available to developers in a “research preview,” but Amazon is also expanding access to its other Nova AI models through a web portal, making them easier to find and use.

Nova Act is a new model whose function sounds similar to OpenAI’s Operator agent. Amazon says Act can carry out web searches, make purchases, or answer questions about what’s on the screen, including the option to perform tasks on a schedule. It can also recognize more detailed instructions — such as telling it “don’t accept the insurance upsell” while making a purchase. Act is currently only accessible to developers, but Amazon says it’s already being put to use carrying out some online tasks in the upgraded Alexa Plus assistant.

Act is the first product to be released by Amazon’s Artificial General Intelligence (AGI) Labs, which says its “dream” is for agents to “perform wide-ranging, complex, multi-step tasks like organizing a wedding or handling complex IT tasks to increase business productivity.” Amazon and OpenAI are far from the only companies chasing AI agents right now, in the hope that people are willing to pay for AI assistants capable of performing tasks rather than simply answering questions or generating Ghibli art.

Act joins the other five Nova models first announced in December 2024, which include a trio of “understanding” models, along with image and video generators. Rather than claiming to offer the most powerful AI models around, Amazon has instead emphasized the speed and value of the Nova suite, which it says are “at least 75 percent less expensive” than comparable rivals.

Amazon is now adding a way for developers and other people in the US to more directly access these models: a website that lets them use the models to answer queries or generate content. The models were previously only available through Amazon Bedrock, an AI model platform within Amazon Web Services that offers access to Nova alongside third-party models from DeepSeek, Anthropic, Meta, and more. Rohit Prasad, SVP of Amazon AGI, says the site is meant to let developers “quickly test their ideas with Nova models, and then implement them at scale in Amazon Bedrock.”
