AI models: Amazon Nova

competition is good... while previous Titan AI models from Amazon are mostly "good enough"

Nova Premier, which can process text, images, and videos (but not audio), is available in Amazon Bedrock, the company’s AI model development platform. Amazon says that Premier excels at “complex tasks” that “require deep understanding of context, multi-step planning, and precise execution across multiple tools and data sources.”

Amazon announced its Nova lineup of models in December at its annual AWS re:Invent conference. Over the last few months, the company has expanded the collection with image- and video-generating models as well as with audio understanding and agentic, task-performing releases.
