+# qwen3-0.6b-math-l45-qlora-merged-fp16-v2
+
+Merged fp16 model from `Qwen/Qwen3-0.6B-Base` plus a QLoRA SFT adapter trained for MATH level 4-5 problem solving.
+
+This is the corrected SFT v2 run using the train split for training. Final 500-question evaluation is intentionally separate.

+```text
+You are a precise mathematical problem solver.
+Follow this exact output contract:
+1. Solve the problem step by step with concise reasoning.
+2. Use valid LaTeX math notation for mathematical expressions.
+3. Preserve LaTeX commands such as \frac{...}{...}, \sqrt{...}, x^{...}, subscripts, equations, and inequalities.
+4. Put the final answer on its own last line exactly in this form: Final Answer: \boxed{...}
+5. Do not use Markdown code fences.
+6. Do not switch to a different answer format.
+```
+
+## Usage
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+import torch
+
+repo_id = "zannvznn/qwen3-0.6b-math-l45-qlora-merged-fp16-v2"
+tokenizer = AutoTokenizer.from_pretrained(repo_id, trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    repo_id,
+    torch_dtype=torch.float16,
+    device_map="auto",
+    trust_remote_code=True,
+)
+```
