-### Testing Data, Factors & Metrics
+### Custom Reward
+
+```python
+def count_xml(text: str) -> float:
+    """
+    Calculates a reward based on the occurrence of certain XML tags and subtracts penalties for content after closing tags.
+
+    Args:
+    text (str): The text string to analyze for XML tag consistency.
+
+    Returns:
+    float: Total reward score based on XML tag occurrence and penalties.
+    """
+    count = 0.0
+    if text.count("<think>\n") == 1:
+        count += 0.125
+    if text.count("\n</think>\n") == 1:
+        count += 0.125
+    if text.count("\n<answer>\n") == 1:
+        count += 0.125
+        count -= len(text.split("\n</answer>\n")[-1])*0.001
+    if text.count("\n</answer>") == 1:
+        count += 0.125
+        count -= (len(text.split("\n</answer>")[-1]) - 1)*0.001
+
+    # Ensure `<think>` and `</think>` exist
+    if "<think>" in text and "</think>" in text:
+        count += 1.0  # Higher weight to ensure reasoning consistency
+    else:
+        count -= 1.0  # Penalize if missing
+
+    return count
+```
+
+Each component contributes to the total reward **if conditions are met**:
+
+| Condition | Reward |
+|-----------|--------|
+| `"<think>\n"` appears exactly **once** | **+0.125** |
+| `"\n</think>\n"` appears exactly **once** | **+0.125** |
+| `"\n<answer>\n"` appears exactly **once** | **+0.125** |
+| `"\n</answer>"` appears exactly **once** | **+0.125** |
+| Both `<think>` and `</think>` exist anywhere | **+1.0** |
+| No extra text after `"</answer>"` | **No penalty** |
+
+Total possible reward **before penalties**:
+\[
+0.125 + 0.125 + 0.125 + 0.125 + 1.0 = 1.5
+\]
+
+**Potential Penalties**
+The function applies penalties for **extra content after `"</answer>"`**:
+\[
+-\left( \text{length of extra text} \times 0.001 \right)
+\]
+If the **best case** occurs (i.e., **no extra content**), then:
+- **Penalty = 0**  
+- **Final Reward = 1.5 (no deductions)**

-<!-- This should link to a Dataset Card if possible. -->
-
-[More Information Needed]
-
-#### Factors
+---
 
-<!-- These are the things the evaluation is disaggregating by, e.g., subpopulations or domains. -->
+**Best Possible Input Example**
+This **ideal input** gives the highest possible reward:
 
-[More Information Needed]
+```xml
+<think>
+Valid reasoning goes here.
+</think>
 
-#### Metrics
+<answer>
+Correct final answer here.
+</answer>
+```
 
-<!-- These are the evaluation metrics being used, ideally with a description of why. -->
+This means we customize the reward function so that we encourage the answer to have reasoning inside. We also know mathematically what the reward should be so we can monitor it during training process.

+### Dataset Used
+The model was fine-tuned on:  
+🔹 [`eagle0504/openai-gsm8k-enhanced-using-together-ai-deepseek-train8k-test1k-v1`](https://huggingface.co/datasets/eagle0504/openai-gsm8k-enhanced-using-together-ai-deepseek-train8k-test1k-v1)
 
-### Results
+This dataset contains:
+- **8K training samples**
+- **1K testing samples**
+- Features: `question`, `answer`, `cot` (Chain-of-Thought)
 
-[More Information Needed]
+### Training Configuration
+- **Framework:** `transformers` + `unsloth` + `trl`
+- **Optimization:** LoRA applied to QKV projections
+- **Learning Rate:** `1e-6`
+- **AdamW Optimizer (8-bit)**
+- **Mixed Precision (`bf16` or `fp16`)**
+- **Batch Size:** `8`
+- **Max Sequence Length:** `1024`
 
-#### Summary
+## Model Performance
 
+### Training Loss
+| Step | XML Count |
+|------|-----------|
+| 10   | -1 |
+| 100  | -1 |
+| 500  | -0.6421 |
+| 750  | 0.7611 |
+| 1000 | 1.0506 |
 
+As we can see, after 1000 steps, we see the reward of XML Count is above 1, which is getting good. This took about `1h 46min 50s` on a T4 GPU in Colab with High RAM.

+### Recommendations
+- If using this model for **critical applications**, verify outputs with human review.
+- For **better performance**, fine-tune on **larger datasets** with real-world numerical reasoning.
