Here’s everything you need to know about Amazon Nova. Amazon Nova offers models tailored to different needs. As with any AI portfolio, Amazon continually evolves the lineup based on what customers need. - **Nova Micro** is a text-only model that delivers the lowest latency responses at very low cost—built for high-volume text processing, real-time generation, chatbots, and code generation where response speed is critical. - **Nova 2 Lite** is a fast, cost-effective reasoning model for everyday workloads. It is ideal for customer service chatbots, document processing, and business automation, with standout capabilities in processing documents, extracting information from videos, generating code, providing accurate answers, and automating multi-step agentic workflows. - **Nova Pro** is Amazon's most capable multimodal model, balancing accuracy, speed, and cost for complex reasoning tasks. It handles text, images, and video, and is recommended for multi-step workflows, knowledge base synthesis, software development, financial analysis, and video reasoning. Organizations can also combine models, using distillation to transfer knowledge from Nova Pro to smaller models for specialized performance, or routing different tasks to different models within the same application. **Nova Forge** enables organizations to build, train, and customize optimized variants of foundation models by blending their proprietary data with Nova's capabilities. Through open training, the service provides exclusive access to pre-trained, mid-trained, and post-trained Nova model checkpoints so customers can mix their proprietary data with Amazon Nova-curated datasets at every stage of training. The result is a customized model that combines Nova's full knowledge and reasoning power with a deep understanding of each organization's specific business. Beyond model checkpoints, Nova Forge offers reinforcement learning “gyms”—synthetic environments where models learn from simulated scenarios. It also offers synthetic data-based distillation for creating smaller, faster models that maintain their intelligence at lower cost, and a responsible AI toolkit for safety controls. Organizations from cutting-edge medical research startups to leading global media brands are using Nova Forge to build custom models and drive efficiencies and innovation in their businesses. Once customers create and train custom models tailored to their needs with Nova Forge, they can deploy them on [Amazon Bedrock](https://aws.amazon.com/bedrock/) with enterprise-grade security, scalability, and data privacy. Available as a service on [AWS](https://www.aboutamazon.com/amazon-aws-news), **Nova Act** enables the building and deploying of highly reliable AI agents that automate browser-based workflows, delivering more than 90% reliability on end-to-end complex tasks. Powered by a custom Nova 2 Lite model trained through reinforcement learning, Nova Act combines three core capabilities—understanding what is on a web page, breaking a complex task into logical steps, and taking action on a browser such as clicking, typing, and scrolling—into one integrated system. It excels at UI-based workflows like updating data in customer relationship management (CRM) systems, filling forms to submit health insurance claims, detecting data on pages that load content dynamically, or testing website functionality and checkout flows. Developers can prototype agents [for free online](https://nova.amazon.com/chat) using natural language prompts, refine them with Python code, and deploy them to AWS through Amazon Bedrock in hours. ![Sound waves in motion.

Available on Amazon Bedrock, it features upgraded reasoning that delivers lower latency, significantly improved tool calling accuracy, and instruction following, helping developers build more reliable, intelligent, voice-first applications. Nova 2.5 Sonic retains the full capabilities of its predecessor, including expressive voices, natural turn-taking, barge-in handling, built-in content moderation, and watermarking, while strengthening the reasoning that powers complex, multi-turn conversational workflows. The model supports seven languages, including English, French, Italian, German, Spanish, Portuguese, and Hindi. **Amazon Nova Multimodal Embeddings** is a state-of-the-art multimodal embedding model for agentic retrieval-augmented generation (RAG) and semantic search applications, available on Amazon Bedrock. It is the first unified embedding model that supports text, documents, images, video, and audio through a single model, enabling crossmodal retrieval with leading accuracy. The model supports context lengths up to 8,000 tokens, text in more than 200 languages, and four output embedding dimensions using Matryoshka Representation Learning. It natively integrates with Amazon OpenSearch Service and Amazon S3 Vectors. Embedding models convert text, visual, and audio inputs into numerical representations that AI systems can compare, search, and analyze. This unlocks insights from unstructured data across multiple content types, powering use cases such as cross-modal search across mixed-modality content, searching with reference images, and retrieving visual documents—eliminating the need to build complex cross-modal embedding solutions or restrict use cases to a single content type. ![Generative AI prompts on nova.amazon.com, on a desktop computer.](https://assets.aboutamazon.com/dims4/default/9526858/2147483647/strip/true/crop/2550x1434+0+0/resize/767x431!/quality/90/?url=https%3A%2F%2Fassets.aboutamazon.com%2Fd2%2Fc7%2F84823bac4a3bb1925162e96ee0f3%2Fhero-large-test-4.jpg) All [Amazon Nova models are available to AWS customers in Amazon Bedrock](https://www.aboutamazon.com/news/innovation-at-amazon/amazon-nova-website-sdk), a fully managed service that makes high-performing foundation models available through a single API.
