Nemotron Labs Dory 1.0 4B is a dense model with 4B parameters. It is a looped model: a shared block of layers is applied several times for each token, so it can spend more compute per token without adding parameters. NVIDIA lists a context window of up to 256K tokens. The model takes text input. The weights are released under the OpenMDW License Agreement v1.1, which allows commercial use.
The official BF16 weights on Hugging Face take about 8.0 GB. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
