This model was trained as part of the paper [When Does Reasoning Matter?](https://arxiv.org/pdf/2509.22193)
It belongs to a collection of **General and Math-specific student models** distilled from Instruction-Fine-Tuned (IFT) or Reasoning answers generated by [Qwen/Qwen3-235B-A22B](https://huggingface.co/Qwen/Qwen3-235B-A22B).

## Datasets
These models were trained on the **largest set of IFT and Reasoning answer pairs**:
- **General dataset**: [general-reasoning-ift-pairs](https://huggingface.co/datasets/When-Does-Reasoning-Matter/general-reasoning-ift-pairs)
- **Math dataset**: [math-reasoning-ift-pairs](https://huggingface.co/datasets/When-Does-Reasoning-Matter/math-reasoning-ift-pairs)
