# What's new in Amazon Nova 2


Amazon Nova 2 introduces significant enhancements across understanding, creative and speech capabilities. The following sections describe the key new features and improvements.

## New models


**Nova 2 Lite**  
Enhanced models that offer advanced reasoning with extended thinking support, three-level intensity control and multimodal understanding optimized for production-scale agentic workflows.

**Nova 2 Sonic**  
An upgraded conversational speech model with improved speech understanding, natural language processing and voice generation capabilities across seven languages.

**Nova Multimodal Embeddings**  
A multimodal embedding model that processes text, image, document, video and audio inputs and generates embeddings.

## New features and capabilities


### Nova Multimodal Embeddings


Nova Multimodal Embeddings supports text, documents, images, video and audio through a single model, enabling cross-modal retrieval applications. Nova Multimodal Embeddings maps each of these content types into a unified semantic space, enabling you to conduct unimodal, cross-modal and multimodal vector operations, powering applications such as agentic retrieval-augmented generation (RAG) and multimodal semantic search.

### Extended thinking and reasoning


Nova 2 Lite supports extended thinking, which allows the models to spend more time reasoning through complex problems before generating responses. This capability improves accuracy for multi-step reasoning tasks, including agentic workflows with multiple tools, advanced mathematics, complex planning and code generation.

### Built-in tools


Amazon Nova 2 includes built-in tools that extend model capabilities without requiring external integrations:
+ **Web grounding** – Accesses real-time information from the web to provide up-to-date responses and reduce hallucinations.
+ **Code interpreter** – Executes Python code to perform calculations.

### AI agent building


Amazon Nova 2 models are optimized for building AI agents. The models provide improved tool use, better reasoning for multi-step tasks and enhanced ability to maintain context across complex agent workflows.

### Improved document understanding


Nova 2 Lite provides enhanced document processing capabilities with better understanding of complex document layouts, tables, charts and multi-page documents. The models extract information more accurately from PDFs, spreadsheets and other document formats.

### Enhanced video understanding


Nova 2 Lite offers improved video analysis capabilities, including better visual perception, temporal understanding, action recognition and the ability to process longer video sequences with higher accuracy.

### Model customization


Nova 2 Lite supports supervised fine-tuning (SFT) and reinforcement fine-tuning (RFT) on Amazon Bedrock and SageMaker AI, allowing you to adapt Amazon Nova 2 to your specific business needs.

### Amazon Nova Forge


Amazon Nova Forge is a first-of-its-kind service that offers organizations the easiest and most cost-effective way to build their own frontier models using Amazon Nova.
