- Who it helps
- Researchers studying reinforcement learning for models that iteratively refine tokens.
- Availability
- The October 26 paper and Apache-2.0 implementation are public. Training documentation uses CUDA PyTorch and eight processes; model and dataset terms are separate.
Measure which steps help
The method uses changes in token confidence and groups tokens by word class when assigning learning credit. The authors report mathematical reasoning gains with LLaDA-8B.

Inspect checkpoint selection
The implementation evaluates on MATH500 during training and selects the best checkpoint by that accuracy. Treat those results with that selection procedure in view, rather than assuming an untouched final test.
