| # UltraAtlas
|
|
|
| UltraAtlas is a high-quality English question-answering dataset prepared by **Dl26** for text-generation and chat-style model training.
|
|
|
| The dataset is converted from **SQuAD v2** into a consistent assistant format with `prompt`, `response`, and `messages` fields. It is intended for supervised fine-tuning of general assistant models that need strong question answering behavior.
|

| ## Intended Use
|
|
|
| UltraAtlas is intended for:
|
|
|
| * supervised fine-tuning of text-generation models
|
| * question-answering behavior training
|
| * single-turn assistant training
