What is Nemotron 3 Nano 30B A3B good for?

NVIDIA publishes this model; we expose it under the id "nvidia/nemotron-3-nano-30b-a3b". Its context window is 262,144 tokens, roughly 197k English words in one request. A single response can run to 235,929 tokens. On price it sits in the "very cheap" band — cheaper than 347 and dearer than 48 of the other paid models in the catalogue.

What it can do beyond plain text: it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; 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.

Pricing is 20,773 toman per 1M input tokens and 83,093 per 1M output tokens. A 1,000-word round trip on Nemotron 3 Nano 30B A3B lands near 135 toman. It supports cached input: repeated context is billed at 4,155 toman per 1M, which matters a lot if your system prompt is long. 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 Qwen3 14B: Nemotron 3 Nano 30B A3B works out about 17% 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 741 thousand-word requests on Nemotron 3 Nano 30B A3B, and every 1,000 toman is about 7,407 words of round trip. A job with one million input tokens and one million output tokens comes to 103,866 toman in total. Filling this model's 262,144-token window costs 5,446 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "nvidia/nemotron-3.5-lightning", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (135 and 122 toman). On parameters the other takes logprobs, min_p, top_logprobs.

NVIDIA has 12 models in our catalogue; the cheapest is Nemotron 3.5 Lightning at 122 toman per thousand words and the dearest Nemotron 3 Ultra at 1,350. Among the less common parameters it accepts logit_bias, presence_penalty, repetition_penalty, top_k — all through the standard request body. By context size the nearest option from another provider is Aion 3.5 at 262,144 tokens.

Good fits: high-volume work such as classification, tagging and bulk summarising, logic puzzles and code review, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
