NVIDIA-Nemotron-Nano-9B-v2

NVIDIA is one of the very few Western companies which continues to release a lot of open models and is often seen as a guest in the Artifact series. It is almost ironic that a company, which is arguably one of the most GPU-rich companies out there, continues to release models which run on limited hardware. Nemotron "Nano", which comes in 9B and 12B sizes, is a hybrid model consisting of both attention and mamba layers. It is also hybrid in the sense that it supports a reasoning and non-reasoning model. They also share (the majority of the) the pre-training data. It is hard to say "don't sleep on NVIDIA" as it is arguably one of the most important companies during the AI boom, but them continuing to release capable, small models AND open data with detailed papers is really commendable. On top of all of that, they make the model available for free on OpenRouter.
