Amazon Announces Enhancements to Nova AI Models
On July 16, 2025, Amazon announced significant new customization capabilities for Amazon Nova AI models in Amazon SageMaker AI.
This update provides a comprehensive suite of model customization options for Nova Micro, Nova Lite, and Nova Pro across the entire model training lifecycle, including pre-training, supervised fine-tuning (SFT), and alignment techniques like Direct Preference Optimization (DPO) and Proximal Policy Optimization (PPO).
These “ready-to-use recipes” on SageMaker AI allow customers to adapt Nova models to their proprietary knowledge, workflows, and brand while maintaining high performance and low latency. This includes support for both parameter-efficient and full-model training options.
Also in July, Amazon announced new language capabilities for Nova Sonic, the multimodal foundation model for speech and text. New languages include French, Italian, and German, alongside its existing English and Spanish capabilities.
Why did Amazon announce these updates?
The updates significantly enhance the value proposition of Amazon’s Nova AI family.
- The customization capabilities on SageMaker AI are a game-changer, moving beyond generic foundation models to enable highly specialized and performant AI for specific enterprise needs. This move allows businesses to fine-tune Nova models with their unique datasets, ensuring that AI-generated outputs are highly relevant and accurate to their domain.
- The addition of on-demand deployment for customized models in Bedrock is also a crucial development, offering cost efficiencies that will make advanced AI more accessible for diverse workloads.
- The expanded language support for Nova Sonic reinforces Amazon’s commitment to building truly global AI solutions, enabling seamless multilingual interactions that are vital for multinational corporations.
These updates demonstrate Amazon’s understanding of enterprise requirements for AI: control, customization, cost-efficiency, and global reach.
Bottom Line
Amazon’s updates for its Nova AI models, specifically the enhanced customization capabilities via SageMaker AI and broader language support for Nova Sonic, strengthen its enterprise generative AI offering.
These advancements will also make Amazon’s Nova family a more compelling choice for organizations seeking to implement scalable, custom, and globally-aware AI solutions.
Enterprises should explore these new features to tailor Nova AI models to their specific business needs, improve the accuracy and relevance of their AI applications, and optimize deployment costs.
