When Does Reasoning Matter?

This model was trained as part of the paper When Does Reasoning Matter? 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.

Datasets

These models were trained on the largest set of IFT and Reasoning answer pairs:

• General dataset: general-reasoning-ift-pairs
• Math dataset: math-reasoning-ift-pairs
