Nemotron-3-Nano-30B-A3B
Description:
This container houses Nemotron-3-Nano-30B-A3B, which is a large language model (LLM) trained from scratch by NVIDIA, and designed as a unified model for both reasoning and non-reasoning tasks. It responds to user queries and tasks by first generating a reasoning trace and then concluding with a final response. The model's reasoning capabilities can be configured through a flag in the chat template. If the user prefers the model to provide its final answer without intermediate reasoning traces, it can be configured to do so, albeit with a slight decrease in accuracy for harder prompts that require reasoning. Conversely, allowing the model to generate reasoning traces first generally results in higher-quality final solutions to queries and tasks.
The model employs a hybrid Mixture-of-Experts (MoE) architecture, consisting of 23 Mamba-2 and MoE layers, along with 6 Attention layers. Each MoE layer includes 128 experts plus 1 shared expert, with 5 experts activated per token. The model has 3.5B active parameters and 30B parameters in total.
The supported languages include: English, German, Spanish, French, Italian, and Japanese. Improved using Qwen.
The container components are ready for commercial/non-commercial use.
