The sleeping large has awoken!
For some time, it appeared like Amazon was taking part in catchup within the race to supply its customers — significantly the thousands and thousands of builders constructing atop Amazon Net Companies (AWS)’s cloud infrastructure — compelling first-party AI fashions and instruments.
However in late 2024, it debuted its personal inner basis mannequin household, Amazon Nova, with textual content, picture and even video technology capabilities, and final month noticed a brand new Amazon Alexa voice assistant powered partly by Anthropic’s Claude household of fashions.
Then, on Monday, the e-commerce and cloud large’s synthetic basic intelligence division Amazon AGI has introduced the discharge of Amazon Nova Act, an experimental developer package for constructing AI brokers that may navigate the online and full duties autonomously, powered by a customized, proprietary model of Amazon’s Nova massive language mannequin (LLM). Oh, and the usual developer package (SDK) is open supply beneath a permissive Apache 2.0 license, although the SDK is designed to work solely with Amazon’s in-house customized Nova mannequin, not any third-party ones.
The purpose is to allow third-party builders to construct AI brokers able to reliably performing duties inside net browsers.
However how does Amazon’s Nova Act stack as much as different agent constructing platforms on the market in the marketplace, comparable to Microsoft’s AutoGen, Salesforce’s Agentforce, and naturally, OpenAI’s just lately launched open supply Brokers SDK?
A special, extra considerate method to AI brokers
Because the public rise of enormous language fashions (LLMs), most “agent” programs have been restricted to responding in pure language or offering data by querying data bases.
Nova Act is a part of the bigger business shift towards action-based brokers—programs that may full precise duties throughout digital environments on behalf of the consumer. OpenAI’s new Responses API, which provides customers entry to its autonomous browser navigator, is one main instance of this, which builders can combine into AI brokers by way of the OpenAI Brokers SDK.
Amazon AGI emphasizes that present agent programs, whereas promising, battle with reliability and sometimes require human supervision, particularly when dealing with multi-step or complicated workflows.
Nova Act is particularly designed to deal with these limitations by offering a set of atomic, prescriptive instructions that may be chained collectively into dependable workflows.
Deniz Birlikci, a Member of Technical Employees at Amazon, described the broader imaginative and prescient in a video introducing Nova Act: quickly, there will probably be extra AI brokers than individuals shopping the online, finishing up duties on behalf of customers.
David Luan, VP of Amazon’s Autonomy Staff and Head of AGI SF Lab, framed the mission extra instantly in a latest video name interview with VentureBeat: “We’ve created this new experimental AI model that is trained to perform actions in a web browser. Fundamentally, we think that agents are the building block of computing,” he mentioned.
Luan, previously a co-founder and CEO of Adept AI, joined Amazon in 2024 as a part of an aqcui-hire. Luan mentioned he has lengthy been a proponent of AI brokers. “With Adept, we were the first company to really start working on AI agents. At this point, everybody knows how important agents are. It was pretty cool to be a bit ahead of our time,” he added.
What Nova Act provides devs
The Nova Act SDK supplies builders with a framework for setting up web-based automation brokers utilizing pure language prompts damaged down into clear, manageable steps.
In contrast to typical LLM-powered brokers that try complete workflows from a single immediate—usually leading to unreliable conduct—Nova Act is designed to incrementally execute smaller, verifiable duties.
Among the key options of Nova Act embrace:
Positive-Grained Activity Decomposition: Builders can break down complicated digital workflows into smaller act() calls, every guiding the agent to carry out particular UI interactions.
Direct Browser Manipulation through Playwright: Nova Act integrates with Playwright, an open-source browser automation framework developed by Microsoft. Playwright permits builders to regulate net browsers programmatically—clicking parts, filling varieties, or navigating pages—with out relying solely on AI predictions. This integration is especially helpful for dealing with delicate duties comparable to coming into passwords or bank card particulars. For instance, as an alternative of sending delicate data to the mannequin, builders can instruct Nova Act to deal with a password subject after which use Playwright APIs to securely enter the password with out the mannequin ever “seeing” it. This method helps strengthen safety and privateness when automating net interactions.
Python Integration: The SDK permits builders to interleave Python code with Nova Act instructions, together with commonplace Python instruments comparable to breakpoints, assertions, or thread pooling for parallel execution.
Structured Data Extraction: The SDK helps structured information extraction by way of Pydantic schemas, permitting brokers to transform display content material into structured codecs.
Parallelization and Scheduling: Builders can run a number of Nova Act cases concurrently and schedule automated workflows with out the necessity for steady human oversight.
Luan emphasised that Nova Act is a software for builders slightly than a general-purpose chatbot. “Nova Act is built for developers. It’s not a chatbot you talk to for fun. It’s designed to let developers start building useful products,” he mentioned.
For instance, one of many pattern workflows demonstrated in Amazon’s documentation reveals how Nova Act can automate condo searches by scraping rental listings and calculating biking distance to coach stations, then sorting the leads to a structured desk.
One other showcased instance makes use of Nova Act to order a particular salad from Sweetgreen each Tuesday, fully hands-free and on a schedule, illustrating how builders can automate repeatable digital duties in a means that feels dependable and customizable.
Benchmark efficiency and a deal with reliability
A central message in Amazon’s announcement is that reliability, not simply intelligence, is the important thing barrier to widespread agent adoption.
Present state-of-the-art fashions are literally fairly brittle at powering AI brokers, with brokers sometimes reaching 30% to 60% success charges on browser-based multi-step duties, in response to Amazon.
Nova Act, nonetheless, emphasizes a building-block method, scoring over 90% on inner evaluations of duties that problem different fashions—comparable to interacting with dropdowns, date pickers, or pop-ups.
Luan underscored why that reliability focus issues. “What we’ve really focused on is how do you actually make agents reliable? If you ask it to update a record in Salesforce and it deletes your database one out of ten times, you’re probably never going to use it again,” he mentioned.
Amazon AGI benchmarked Nova Act towards competing fashions together with Anthropic’s Claude 3.7 Sonnet and OpenAI’s CUA mannequin. On the ScreenSpot Net Textual content benchmark, which exams instruction-following on textual display parts, Nova Act achieved a rating of 0.939, outperforming Claude 3.7 Sonnet (0.900) and OpenAI CUA (0.883).
Amazon Nova Act benchmarks. Credit score: Amazon
On the ScreenSpot Net Icon benchmark, which focuses on visible UI parts, Nova Act scored 0.879, once more forward of the opposite fashions.
Nonetheless, on the GroundUI Net benchmark, which exams basic UI interplay, Nova Act scored 0.805, barely behind its opponents.
These scores have been measured internally by Amazon utilizing constant prompts and analysis standards.
Amazon additionally highlighted early leads to Nova Act’s means to generalize past commonplace environments.
As an example, staff member Rick Liu demonstrated how the agent, with out specific coaching, efficiently interacted with a pigeon-themed net recreation—assigning stats, battling opponents, and progressing within the recreation.
In response to Luan, that means to generalize is central to the long-term imaginative and prescient. “Our goal with Nova Act is to be a universal browser-use solution. We want an agent that can do anything you want to do on a computer for you,” he mentioned.
Versatile to be used in several clouds, however locked to Amazon’s Nova mannequin
Whereas Nova Act is accessible to builders globally by way of nova.amazon.com, Luan clarified that the system is tightly coupled to Amazon’s in-house Nova basis fashions.
Builders can not plug in exterior LLMs comparable to OpenAI’s GPT-4o or Anthropic’s Claude 3.7 Sonnet, not like with OpenAI’s Brokers SDK, and to a lesser extent, Microsoft’s AutoGen and Salesforce’s Agentforce platforms (which permit switching to some totally different supplier firms and mannequin households).
“Nova Act is a custom trained version of the Nova model,” he mentioned. “It’s not just a scaffolding over a generic LLM. It’s natively trained to act on the internet on your behalf.”
Nonetheless, Nova Act isn’t restricted to AWS environments. Builders can obtain the SDK and run it domestically, within the cloud, or wherever they select. “You don’t need to be on AWS to use it,” Luan acknowledged.
Thus, for companies on the lookout for most underlying mannequin flexibility for his or her brokers, Nova Act might be not the only option. Nonetheless, for these on the lookout for a purpose-built mannequin particularly designed to navigate the online and carry out actions throughout all kinds of internet sites with very totally different consumer interfaces (UIs), it’s most likely price a glance — particularly should you’re already within the Amazon or AWS developer ecosystem.
Safety, licensing and pricing
The Nova Act SDK is launched beneath the Apache License, Model 2.0 (January 2004), an open supply license. Nonetheless, this is applicable solely to the SDK software program.
The Nova Act mannequin itself, together with its weights and coaching information, is proprietary and stays closed-source. The method is intentional, in response to Luan, who defined that the mannequin is tightly built-in and co-trained with the SDK to attain reliability.
At launch, Nova Act is obtainable as a free analysis preview. There is no such thing as a introduced pricing for manufacturing use but.
Luan described this part as a chance for builders to experiment and construct with the expertise. “Our belief is that the majority of the most useful agent products have not yet been built. We want to enable anybody to build a really useful agent, whether for themselves or as a product,” he mentioned.
Long run, Amazon plans to introduce production-grade phrases, together with usage-based billing and scaling ensures, however these will not be but obtainable.
What’s subsequent for Nova Act?
The discharge of Nova Act displays Amazon’s broader ambition to make action-oriented AI brokers a foundational element of computing.
Luan summed up the chance forward: “My personal dream is that agents become the building block of computing, and the coolest new startups and products get built on top of what our team is developing.”
The Nova Act SDK is out there now for experimentation and prototyping on Amazon’s web site and on Github.
