Amazon Nova Premier

Amazon Nova Premier reached general availability on 30 April 2025 as the top rung of the first Nova ladder — the multimodal model for complex reasoning, long documents, large codebases and multistep agentic work. It reads text, images and video, writes text only, carries a one-million-token context window and returns up to 25,000 tokens. Its knowledge cutoff is October 2024, and reasoning is supported. What set Premier apart from rival flagships was not a benchmark claim but a job description. Amazon positioned it explicitly as a teacher: through Bedrock Model Distillation, Premier's behaviour could be distilled into cheaper, faster versions of Nova Pro, Lite and Micro for a specific task. That is why the model was never fine-tunable itself and never offered provisioned throughput — it was the source, not the product. It ran only in the US East (N. Virginia) region and AWS GovCloud (US-West), reaching Ohio and Oregon through cross-region inference. The profile is now a lifecycle document. Amazon's Bedrock model card marks Premier as Legacy with an end-of-life date of 14 September 2026, the same day Nova Sonic goes dark; Nova Canvas and Nova Reel follow on 30 September 2026. The successor generation, announced at re:Invent on 2 December 2025, ships a single general model to the public — Nova 2 Lite — while the more capable Nova 2 Pro stayed in preview for customers of Amazon Nova Forge. One dating note for readers comparing sources: Amazon's own Bedrock model card lists a launch date of 31 October 2025, which reflects the revision catalogued in Bedrock rather than the model's public debut in April 2025.
