# Reasoning Qwen2.5 1.5B

Reasoning Qwen2.5 1.5B model to solve grade-level math with explicit structure: a short scratchpad in `<reasoning>…</reasoning>` and a single final number in `<answer>…</answer>`.

Training: https://github.com/KickItLikeShika/llm-reasoning

I split the training in two stages:
1. Short LoRA SFT on 100 random GSM8K training examples, to teach format + roughly sensible traces, not to maximize benchmark score.
2. GRPO on top of that adapter for 2,000 steps.
