A research company needs to analyze legal documents.

The verified answer is D. Amazon Nova Premier. The decisive requirement is the combination of a 1 million-token context window, multimodal document understanding, chart analysis, and video input. AWS documentation identifies Amazon Nova Premier as the most capable multimodal Amazon Nova understanding model. It supports text, image, and video inputs and generates text output. AWS also lists Amazon Nova Premier with a 1M context window, while Amazon Nova Pro and Amazon Nova Lite support 300k, and Amazon Nova Micro supports 128k and is text-only. Because the company’s legal documents are up to 1 million tokens long, Nova Premier is the only listed option that satisfies the context-length requirement.

AWS documentation also states that Amazon Nova Premier has a supported context length of 1 million tokens, which AWS equates to 1 million tokens of text, 500 images, or 90 minutes of video. The same documentation explains that Nova Premier excels at question answering on long documents. This directly matches the research company’s need to analyze very long legal documents and ingest video summaries for compliance reporting.

Amazon Nova Micro is incorrect because it is a text-only model and has a smaller context window. It cannot process embedded high-resolution charts or video inputs. Amazon Nova Lite is incorrect because it is multimodal, but its context window is 300k, which is below the 1 million-token requirement. Amazon Nova Pro is also incorrect for the same reason: it is highly capable and multimodal, but its context window is 300k rather than 1M. The requirement is not simply “multimodal”; it is long-context multimodal analysis at the 1 million-token scale. Therefore, the only model that fully meets the requirements is Amazon Nova Premier.
