Amazon: Nova Premier 1.0

The user who benefits most here is one already building on Amazon's stack who needs a top-tier reasoning model and, notably, a strong teacher for distilling custom smaller models. It is described as the most capable of Amazon's multimodal line for complex reasoning, and it offers a 1,000,000-token context window, vision for image input, and tool and function calling. A fitting scenario: a team uses it to generate high-quality reasoning traces over long, image-laden documents, then distils that behaviour into a cheaper in-house model for production. Unlike Claude Sonnet 5 or ChatGPT, which are sold primarily as end-user assistants, this leans on its distillation-teacher role and multimodal reasoning as the differentiator. The clear caveat is above-average pricing at $2.50 per 1M input tokens, with no free tier, so it is a considered choice rather than a default. Ideal for organisations that need capable long-context multimodal reasoning and intend to distil custom models from a strong teacher. Choose it when the distillation workflow and multimodal depth justify the premium; look to cheaper models if you only need a general assistant and cannot absorb the higher per-token rate.
