Amazon Nova announcements at re:Invent 2025 : Advanced AI Foundation Models and Services for Reasoning, Multimodal Intelligence, and Agentic AI
The article provides a brief overview of all six Nova announcements at re:Invent, outlining how each model and service contributes to expanded capabilities of the overall family and introduces new ways for developers to build with AI.
At re:Invent 2025, Amazon introduced the next generation of Amazon Nova foundation models and services that deliver industry-leading price-performance across reasoning, multimodal generation, real-time conversation, and agentic automation. Below is a summary of all six announcements:
⭐ Nova 2 Lite, a fast, cost-effective reasoning model for everyday tasks. This is also the best model to use with Nova Forge.
🧠 Nova 2 Pro (Preview), our most intelligent model for complex AI workload. This is also the best teacher model for distillation.
🎤 Nova 2 Sonic, a speech-to-speech model for conversational AI. The second generation adds support for new languages (Portuguese, Hindi), and new capabilities such as polyglot voices, cross-model support, turn-taking construability, asynchronous tool use and more.
🖼️ Nova 2 Omni (Preview), a all-in-one model for multimodal reasoning and image generation
🛠️ Nova Forge, a first of it’s kind service that offers organization the easiest and most cost-effective way to build own frontier models
🤖 Nova Act - build and manage fleets of agents for automating production UI workflows with high reliability.

Section 1: Key capabilities and features at a glance
- Adjustable Thinking Budget: Toggle reasoning on/off, choose low/medium/high thinking levels based on your task complexity—from fast chatbot responses to sophisticated multi-step agentic workflows
- True Multimodal with Long Context: Process text, images, video, and speech with 1M token context—handle 400+ page documents, 90-minute videos, or massive codebases in a single prompt
- Built for Agents: Native support for tools, APIs, and MCP servers - enabling developers to build agentic systems that can plan actions, call external tools, update systems, and deliver completed results.
- Responsible AI: Built-in safety controls and content moderation with advanced robustness to adversarial attacks
- Nova Act uses reinforcement learning while the agents run inside custom synthetic environments (“web gyms”) that simulate real-world UIs. This vertical integration across the model, orchestrator, tools, and SDK, all trained together, unlocks higher completion rates at scale. The result is an agentic system that doesn’t merely work occasionally but is reliable at scale.
- Nova Forge addresses the limitations of current customization approaches by allowing you to start model development from early checkpoints across pre-training, mid-training, and post-training phases. You can blend your proprietary data with Amazon Nova-curated data throughout all training phases, running training using proven recipes on Amazon Sagemaker AI fully managed infrastructure.
Section 2: How Nova performs across industry benchmarks
Nova 2 models deliver substantial improvements over the previous generation. For example, Nova 2 Lite is more intelligent than previous best model, Nova Premier, while being 7× lower in cost and 5x faster in speed.
Amazon Nova 2 Lite and Nova 2 Pro (Preview) demonstrate exceptional performance in agentic workflows. They lead on Tau-bench (tool-use and agentic reasoning), IF-Bench (instruction following), and ScreenSpot (user-interface grounding). They also excel at LongCodeBench 1M for long context reasoning, and AIME for advanced match.
Nova 2 Sonic delivers industry leading conversational quality and price-performance. The table below highlights how Nova 2 Sonic outperforms competitive real-time models across key speech benchmarks - including ASR (speech understanding accuracy), and Big Bench Audio (speech reasoning).
Nova Act delivers strong agentic execution with excellent performance on REAL Bench V2 and ScreenSpot V2 Web Text that highlight its reliability in real-world reasoning and UI-grounded action.
Section 3: Availability of Nova models and services
Amazon Nova 2 Lite and Nova 2 Pro (Preview) are now available in Amazon Bedrock via global cross region inference in multiple locations. Nova 2 Pro is in preview with early access available to all Amazon Nova Forge customers. If interested, reach out to your AWS account team regarding access. Nova 2 Omni is in preview with early access available to all Nova Forge customers. Please reach out to your AWS account team for access. Nova 2 Sonic is available in Amazon Bedrock in the following AWS Regions: US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), and Europe (Stockholm). Nova Forge is available today in US East (N. Virginia) AWS Region and will be available in additional regions in the coming months. Nova Act is available today in AWS Region US East (N. Virginia).
