Nova is a new family of multimodal AI models that Amazon presented at its in-house trade fair re:Invent. The text-based model is available in four different versions: Micro, Lite, Pro and Premier. The image generator is called Nova Canvas, the video generator is called Nova Reel.
The basic model can handle 15 different languages, but is primarily specialized in English. This basically applies to all models from all providers. Nova Micro is optimized exclusively for text, so the latency is particularly low. Nova Lite can process text, images and videos and remains very fast – but also rather inaccurate. With Nova Pro, the focus is on a balance between speed, cost and accuracy, i.e. the model does not react quite as quickly, but is somewhat more accurate. Nova Premier is the most powerful and most expensive model, which can take on complex tasks, but also takes its time.

Amazon has presented the largest model more as a model that can be used to develop your own models based on it. All versions are already available for Amazon customers. AWS Bedrock can be used for fine-tuning and further customization. Nova should be particularly suitable for orchestrations, i.e. also for certain automations. The context windows are to be expanded in the coming year. Micro currently comes with a 128,000 token context window, which is roughly equivalent to processing 100,000 words. Lite and Pro should be able to process around 300,000 tokens, which means 30 minutes of film material, for example.
Generating images and videos with Amazon Nova
Canvas is a classic image generator that also allows you to edit images afterwards. Reel can be used to create videos up to six seconds long. Settings can also be specified and videos edited. It takes around three minutes to generate a video. The videos will soon be able to be longer. According to Andy Jassy, Amazon is also working on a pure AI voice assistant.
Of course, Amazon promises that all Nova models come with the highest security precautions. Amazon is keeping background information on the training data and the structure of the models to itself.
