Nex Agent-SFT Dataset

Paper | Code | Project Page

Dataset Description

This dataset is specifically designed for training the agentic capabilities of Large Language Models (LLMs). The dataset covers multiple agent scenarios and aims to enhance model performance in autonomous decision-making, tool usage, code generation, and interactive task handling. We reselected some of the training queries from the NEX-N1 training dataset and regenerated the responses based on DeepSeek-V3.1-Nex-N1. This data can provide a reference for the community to train and develop new agent models.

Dataset Structure

Each example in the dataset contains the standard instruction-tuning data points as follow:

  • uuid (str): a unique identifier
  • messages (list): message format used for supervised fine-tuning (this contains systerm prompt, user prompt, assistant responses and tool response)
  • tools (list): the list of tool definitions, where each definition includes a tool name, a description, and parameters defined by properties.
  • generator (str): the model name for generating responses.
