What is Nova 2 Lite good for?

Nova 2 Lite comes from Amazon; in uttapen you reach it with the model id "amazon/nova-2-lite-v1". It accepts up to 1,000,000 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 65,535 tokens. On price it sits in the "mid-range" band — cheaper than 160 and dearer than 223 of the other paid models in the catalogue.

Capabilities available on this id: it reads images directly, which makes it a real option for invoices, forms and screenshots; it takes files such as PDFs as input; it supports tool calling, so it can invoke your own functions with valid arguments; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

For a back-of-envelope figure: about 1,260 toman per 1,000-word exchange (103,866 in, 865,548 out, per 1M tokens). You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.

The closest alternative with the same capabilities from a different provider is Seed 2.1 Turbo: Nova 2 Lite works out about 9% cheaper, and its context window is larger. Both run on the same key and the same code, so trying the other one is a single string change.

To make the figure concrete: 100,000 toman of credit buys roughly 79 thousand-word requests on Nova 2 Lite, and every 1,000 toman is about 794 words of round trip. A job with one million input tokens and one million output tokens comes to 969,414 toman in total. Filling this model's 1,000,000-token window costs 103,866 toman on the input side alone, which is the real reason to keep conversation history short.

Amazon has 5 models in our catalogue; the cheapest is Nova Micro 1.0 at 79 toman per thousand words and the dearest Nova Premier 1.0 at 6,751. Among the less common parameters it accepts top_k — all through the standard request body. It does not support response_format, seed, structured_outputs, which most models here do, so test before switching if your code relies on them. By context size the nearest option from another provider is Claude Fable 5 at 1,000,000 tokens.

What to use it for: product chatbots and internal assistants, where cost and quality have to balance, logic puzzles and code review, pulling text and fields out of images, agents that reach out to APIs and databases, analysing a long document or codebase in one request.
