Nemotron-Post-Training-Dataset-v1
Nemotron-Post-Training-Dataset-v1 Release
This dataset is a compilation of SFT data that supports improvements of math, code, stem, general reasoning, and tool calling capabilities of the original Llama instruct model Llama-3.3-Nemotron-Super-49B-v1.5.
Llama-3.3-Nemotron-Super-49B-v1.5 is an LLM which is a derivative of Meta Llama-3.3-70B-Instruct (AKA the reference model).
Llama-3.3-Nemotron-Super-49B-v1.5 offers a great tradeoff between model accuracy and efficiency. Efficiency… See the full description on the dataset page: https://huggingface.co/datasets/nvidia/Nemotron-Post-Training-Dataset-v1.Llama-Nemotron-Post-Training-Dataset

Mix-Context Post-Training Dataset for 128K Context Extension
Overview
Mix-Context Post-Training 128K is a dataset designed specifically for post-training context window extension of pretrained LLMs.
It targets the stage after base pretraining, where a model is adapted to operate over much longer contexts (up to 128K tokens) while preserving short-context behavior. The dataset mixes short- and long-context packed sequences with a controlled length distribution to support:… See the full description on the dataset page: https://huggingface.co/datasets/ghostcc3/mix-context-post-training-128k.webui-training-dataSwallow-Nemotron-Post-Training-Dataset-v1-ja-cpt

Dataset Summary
This dataset is a post-training corpus used in the Typhoon-S recipe for building Sovereign AI: high-performing, region- and domain-specific LLMs that remain localized, controllable, and resource-efficient. It is designed to help transform a sovereignty-adapted base model into a capable assistant while preserving target-language strengths.
The dataset follows a two-part mixture philosophy:
