Small models pass a moment. In the wake of the issuance of the new artificial intelligence form model Small enough to fit a smart watch from Mit Spinoff Liquid AiAnd a small model It is enough to run a Google smartphoneand Nvidia joins the party today with New Small Language Model (SLM) On its own, Nemotron-nano-9B-V2,, Which achieved the highest performance in its class on specific criteria and comes with the ability of users to change and stop “thinking”, that is, protect the self before taking an answer.

While the parameters are 9 billion larger than some of the parameters that include millions of small models covered by Venturebeat recentlyNVIDIA notes that it is a meaningful reduction in its original size of 12 billion teachers And designed to fit Nvidia A10 graphics processing unit.

As oleksii kuchiaev, NVIDIA manager of AI model after training, He said on x In response to a question she presented to him: “12B to 9B has been trimmed to suit A10 specifically, which is a common GPU choice for publication. It is also a mixed model that allows it to process a larger batch size and up to 6X is faster than the similar transformer models. “

For context, many leading LLMS in the range of 70+ billion parameters (call parameters refer to the internal settings that govern the form of the model, with generally indicating a larger and more capable model).


Artificial intelligence limits its limits

Power caps, high costs of the symbol, and delay are reshaped. Join our exclusive salon to discover how the big difference:

  • Transforming energy into a strategic advantage
  • Teaching effective reasoning for real productivity gains
  • Opening the return on competitive investment with sustainable artificial intelligence systems

The model takes on multiple languages, including English, German, Spanish, French, Italian, Japanese and in extended, Korean, Portuguese, Russian and Chinese descriptions. It is suitable for both of them The following instructions and the code generation.

Nemotron-nano-9B-V2 and Data sets before training It is now available in the face of embrace and through the company’s Catalog.

Integration of the transformer structure and mamba

It depends on Nemotron-hMAMBA’s hybrid remittance models that constitute the basis for the latest offers of the company.

While the most popular LLMS are pure “adapter” models, which are entirely dependent on attention layers, they can become expensive in memory and account with the growth of sequence lengths.

Instead, Nemotron-H models and others using Mamba structure developed by the researchers At the University of Carnegie Mellon and Bruneston, too Weave in selective status space models (or SSMS), which can handle very long sequences of information inside and outside the situation.

These layers expand in line with the length of the sequence and can address the contexts for a much longer period of self -interest without the same memory and calculating public expenditures.

AYBRID MAMBA reduces these costs by replacing most of the attention with the layers of the linear area, and achieving up to 2-3 x production higher on long contexts Similar accuracy.

Other Amnesty International Labs outside NVIDIA like AI2 also released models Depending on the architecture Mampa.

Switching/thinking using language

Nemotron-nano-9B-V2 is placed as a uniform model, only chat and logic trained from scratch.

the The default settings of the system to create a thinking track before providing a final answer, although users can switch this behavior By simple control codes such as /thinking or /no_tkink.

The model is also mentrduces operating time management “thinking budget”any The developers allow this number of symbols I devoted to internal thinking before the form complements the response.

This mechanism aims to balance accuracy with cumin, Especially in applications such as customer support or independent agents.

Standards tell a promising story

The evaluation results shed light on the competitive accuracy against other open models on a small scale. It was tested in “Thinking” mode using the Nemo-Skills Suite, NEMOTRON-NANO-9B-V2 reaches 72.1 percent on Aime25and 97.8 percent on Math500, 64.0 percent on GPQAAnd 71.1 percent on LiveCodebench.

The degrees have been reported on the following instructions and long -context standards: 90.3 percent on IFEVAL, 78.9 percent in the 128K testSmaller but measurable gains on BFCL V3 and Hle standard.

In all areas, NANO-9B-V2 shows a higher resolution than QWEN3-8B, A common point for comparison.

NVIDIA explains these results with accuracy curves against a budget that shows how performance standards increase with an increase in the distinctive symbol of thinking. The company suggests that the exact budget control can help developers to improve both quality and cumin in cases of production.

Training on artificial data collections

Both Nano and the Nemotron-H Family rely on a mixture of coordinated training data and sources on the web and artificial.

The company includes the general text, symbol, mathematics, science, legal and financial documents, as well as the proficiency data groups similar to alignment.

NVIDIA confirms the use of artificial thinking effects caused by other large models to enhance performance on complex standards.

License and commercial use

The NANO-9B-V2 is released below NVIDIA Open Forms Licensing AgreementThe last update in June 2025.

The license is designed to be easily and friendly to institutions. Nvidia expressly states that the models Commercially Outside the boxAnd that The developers are free to create and distribute models.

More importantly, NVIDIA does not claim the ownership of any outputs created by the form, which leaves responsibility and rights with the developer or institution he uses.

As for the organization’s developer, this means that the model in production can be placed immediately without negotiating a separate commercial license or paying fees related to the threshold of use or revenue levels or user census. There are no items that require a paid license once the company reaches a specific range, unlike some of the gradual open licenses used by other service providers.

However, the agreement includes many conditions that institutions must notice:

  • HandrailsUsers cannot overcome or disrupt the integrated safety mechanisms (referred to as “handrails”) without implementing similar alternatives suitable for publishing them.
  • redistribution: Any redistribution of the model or derivatives must include the NVIDIA Open Model License (“Licensed by Nvidia Corporation under NVIDIA Open Model”).
  • complianceUsers must comply with commercial regulations and restrictions (for example, American export laws).
  • Conditions of artificial intelligence worthy of confidenceUsing must be consistent with the advisory instructions worthy of trust in NVIDIA, which cover responsible publishing and moral considerations.
  • The requirement for litigation: If the user begins copyright or litigation in patents against another entity that claims to be violated by the model, then the license ends automatically.

These conditions focus on legal and responsible use instead of commercial scope. Institutions do not need to request additional permission or pay royalties to NVIDIA just to build products, liquefy them, or limit the user base. Instead, they must make sure that publishing practices respect safety, support and compliance obligations.

GPS in the market

With Nemotron-Nano-9B-V2, NVIDIA targets developers who need a balance between thinking ability and publishing efficiency on smaller measures.

Control features of the operating time budget and logic features aim to give system builders more flexibility in managing accuracy against response speed.

Their launch of the embrace of the face and the typical Nafidia chocolate indicates that they are It is supposed to be widely available for experience and integration.

The NVIDIA Nano-9 V2 version shows a constant focus on the efficiency and thinking that can be controlled in language models.

By combining the hybrid structure with new pressure and training techniquesThe company provides developers tools that seek to maintain accuracy while reducing costs and cumin.
