# NVIDIA-Nemotron-3-Super-145B-A13B-Coder-NVFP4

A coding-specialized expansion of
[NVIDIA Nemotron 3 Super 120B-A12B NVFP4](https://huggingface.co/nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-NVFP4).

This is a community model and is not an official NVIDIA release. It was
inspired by NVIDIA's open-model, open-data, and open-tooling work around
Nemotron.

## Model Summary

| | |
|:---|:---|
| **Total Parameters** | Approximately 145B |
| **Active Parameters** | Approximately 13B per token |
| **Quantization** | NVFP4 mixed-precision checkpoint |
| **Architecture** | Nemotron hybrid Mamba-2, LatentMoE, Attention, and MTP |
| **Maximum Context Length** | 262,144 tokens (256K) |
| **Specialization** | Agentic coding, reasoning, tool use, multi-turn software-engineering workflows, and SVG generation |
| **Base Model** | [NVIDIA-Nemotron-3-Super-120B-A12B-NVFP4](https://huggingface.co/nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-NVFP4) |

## Does This Work?

The public
[Nemotron 130B LLMWildling Canary NVFP4](https://huggingface.co/LLMWildling/Nemotron-130b-llmwildling-canary-nvfp4)
provides a smaller proof point. It demonstrates direct recall of newly added
domain knowledge and carries that knowledge into a follow-up task without RAG
or prompt-injected context.

## SVG Evaluation

This version received a small amount of SVG-focused training. During interactive
evaluation, it produced these playable SVG Flappy Bird-style outputs.

## Intended Use

This checkpoint is ready for production use in coding assistants, repository
analysis, agentic software-engineering systems, tool-using workflows, and
interactive SVG generation.
