AWS re:Invent 2025 - Nova 2: Enterprise intelligence optimized for the real world

Introduction to Amazon Nova

• Amazon has been shipping AI innovations for decades, building industry-leading technologies at each critical inflection point.
• Amazon offers a comprehensive stack of AI capabilities, from custom compute to turnkey solutions and specialized expertise.

Amazon Bedrock and Amazon Nova

• Amazon Bedrock is a comprehensive service for generative AI application and agent development, providing access to leading foundation models and tools.
• Amazon Nova is a family of AI models used by thousands of customers across many industries to build AI solutions.

Introducing Amazon Nova 2

• Amazon Nova 2 is the next generation of Amazon's AI models, delivering industry-leading price-performance across reasoning, multimodal, and conversational AI use cases.
• The Nova 2 model family includes:
  • Nova 2 Light: A fast, cost-effective reasoning model for everyday workloads
  • Nova 2 Pro: The most intelligent reasoning model for highly complex tasks
  • Nova 2 Omni: The industry's first unified multimodal reasoning model
  • Nova 2 Sonic: The next-generation speech-to-speech model for real-time conversational AI

Key Capabilities of Nova 2

Developer Controls

• Nova 2 provides developers the ability to toggle reasoning on/off and adjust reasoning levels to manage latency and cost.
• Demonstration shows how low-level reasoning can improve performance on a complex document analysis task.

Multi-Step Reasoning

• Nova 2 can break down complex tasks, reason through them, and call the right tools in the right order to complete workflows.
• Example shows an agent using Nova 2 to navigate, analyze, and update a repository to enable extended reasoning capabilities.

Native Tool Use

• Nova 2 offers higher reliability and accuracy when using external tools, including a built-in code interpreter and web grounding.
• Example demonstrates how Nova 2 can use a Python code interpreter to perform complex math calculations.

Extended Context

• Nova 2 supports long context, enabling reasoning over large documents, videos, and other extensive inputs.
• Example shows Nova 2 building a web app for a real estate agent, using long context to iteratively improve the generated code and functionality.

Customer Examples

• Siemens found Nova 2 Light to be up to 3x faster than other models while maintaining high-quality responses.
• Trelllex saw a 39% improvement in threat classification and over 3x more detailed responses with better technical analysis when upgrading from Nova 1 to Nova 2.

Real-World Evaluation Methodology

• The AWS team works closely with customers to understand their specific use cases and requirements.
• They build comprehensive evaluation sets, run continuous testing, and analyze model outputs in detail to identify failure modes and improve prompts and data.
• Key use cases evaluated include classification, document extraction, and agent-based workflows.

Nova Forge: Customizing Nova Models

• Nova Forge allows customers to build custom models tailored to their specific needs, using techniques like data mixing, reinforcement fine-tuning, and continued pre-training.
• Example shows a 21% lift in classification performance when fine-tuning Nova 2 Light using Nova Forge.

Zenesk's Use of Nova

• Zenesk is using Nova to power their AI-driven customer service platform, which aims to make customer service radically better.
• Key use cases include:
  • Multilingual support through bi-directional translation, supporting over 30 languages
  • Automated resolutions, with the goal of 80%+ of interactions being solved end-to-end by AI

Conclusion

• Nova 2 models are now available, offering significant improvements in price-performance and capabilities.
• Customers can experiment with Nova models at nova.amazon.com and nova.amazon.com/dev.
• Nova Forge enables deeper customization of Nova models to suit specific business needs.
