Amazon has unveiled a major expansion of its Nova AI portfolio, introducing four new Frontier Nova models, launching a groundbreaking service called Nova Forge that enables organizations to build their own custom model variants, and unveiling Nova Act—a new offering designed to create highly reliable AI agents for web-based tasks. The new Frontier Nova models are engineered to deliver advanced performance across complex reasoning, coding, and multimodal capabilities, positioning them at the forefront of generative AI innovation. These models are tailored to meet the demands of enterprise-grade applications, supporting everything from intricate decision-making workflows to sophisticated content generation. Nova Forge represents a significant leap in model customization, offering organizations a secure, scalable, and open training environment. With this service, businesses can fine-tune and train their own versions of Nova models using proprietary data, allowing for greater control, compliance, and performance optimization. The open training approach is designed to empower developers and data scientists to innovate without being constrained by closed ecosystems. Nova Act is a new service that enables the creation of robust, reliable AI agents capable of performing complex, multi-step tasks in web browsers. These agents can navigate websites, extract information, fill forms, and execute workflows autonomously—making them ideal for automating customer service, data collection, and internal operations. Built with safety, consistency, and reliability in mind, Nova Act reduces the risk of errors and hallucinations common in earlier agent systems. The announcements were made during Amazon’s keynote at the AWS re:Invent conference in Las Vegas, underscoring Amazon’s commitment to advancing AI accessibility and enterprise readiness.
