Amazon CEO Andy Jassy introduced six new generative AI models, collectively known as Amazon Nova, at the re:Invent conference. These multimodal models offer capabilities in text, image, and video generation, targeting various needs and price points.
Exploring the Nova Family
The Nova family comprises several specialized models:
- Nova Micro: A text-only model designed for quick, cost-effective responses.
- Nova Lite: A multimodal model for processing image, video, and text inputs at a lower cost.
- Nova Pro: A versatile multimodal model balancing accuracy, speed, and cost for diverse tasks.
- Nova Premier: Amazon’s most powerful multimodal model, aimed at complex reasoning tasks (available Q1 2025).
- Nova Canvas: A dedicated text-to-image generation engine.
- Nova Reel: A specialized model for generating short-form videos.

The text-based models support 15 languages. Nova Micro boasts a 128,000-token context window, while Lite and Pro handle up to 300,000 tokens (equivalent to roughly 225,000 words or 30 minutes of video). Amazon plans to extend the context windows of larger models to 2 million tokens in early 2025.
Nova’s Creative Capabilities
Nova Canvas allows users to create and modify images through natural language prompts. Nova Reel, competing with established video generators like Gen-3 Alpha, Kling, and Dall-E 3, generates up to six-second video clips from text prompts and reference images, incorporating camera movements like pans and zooms.
Performance and Availability
Jassy highlighted Nova’s cost-effectiveness and speed, though benchmark data is yet to be released. He emphasized the models’ optimization for proprietary systems and APIs, facilitating complex automated workflows.
Nova Micro, Lite, Pro, Canvas, and Reels are currently available to AWS customers. Nova Premier is scheduled for release in Q1 2025.
Conclusion
Amazon Nova represents a significant expansion of Amazon’s AI offerings, providing a range of generative AI models for diverse applications. The family’s focus on multimodal capabilities, cost-effectiveness, and speed positions it as a strong contender in the rapidly evolving generative AI landscape. The availability of specialized models like Canvas and Reels further expands the creative possibilities for developers and content creators.
