 ## Model Details
 - **Base model:** [`Qwen/Qwen2.5-Math-1.5B`](https://huggingface.co/Qwen/Qwen2.5-Math-1.5B)
-- **Method:** TreeRPO (tree-structured GRPO; up to depth 7; branching by entropy & length)
+- **Method:** TreeRPO (tree-structured GRPO;)
 - **Reward signal:** Deterministic exact-match checker (binary). Interior node rewards = mean descendant leaf rewards.
 - **Domain:** Grade-school and intermediate math word problems (GSM8K style)
