+# Llama-3.2-1B-MathCodeInstruct-5k
+
+A [Llama-3.2-1B](https://huggingface.co/unsloth/Llama-3.2-1B) fine-tune on **5k examples** from
+[MathLLMs/MathCodeInstruct](https://huggingface.co/datasets/MathLLMs/MathCodeInstruct), trained to solve math
+word problems with step-by-step natural-language reasoning interleaved with executable Python.
+
+This is one of three sibling models trained on {5k, 10k, 20k}-example subsets of the same dataset, to study how
+fine-tuning data volume trades off against both math performance and general capability. See the
+[training write-up](https://github.com/OliverSundaram/finetuning-Llama3.2-1B) for the full comparison across all three.

+## Benchmark results
+
+All benchmarks run with [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness), each at
+its standard published shot count, compared against the un-tuned base model.
+
+| Benchmark | Llama-3.2-1B (base) | This model | Change |
+|---|---|---|---|
+| GSM8K | 5.8% | 7.4% | 🟢 +1.5% |
+| ARC-Challenge | 36.9% | 36.8% | ⚪ -0.1% |
+| HellaSwag | 64.2% | 63.8% | 🔴 -0.3% |
+| WinoGrande | 60.8% | 62.4% | 🟢 +1.7% |
+
+**Speed** (single-request generation, greedy, RTX 4060): **38.36 tokens/sec**
+(base model: 12.74 tokens/sec)

+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "OliverSundaram/Llama-3.2-1B-MathCodeInstruct-5k}"
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="bfloat16", device_map="auto")
+
+messages = [
+    {"role": "system", "content": "Below is a math problem. Please solve it step by step."},
+    {"role": "user", "content": "If a train travels 60 miles in 45 minutes, what is its speed in miles per hour?"},
+]
+inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
+output = model.generate(inputs, max_new_tokens=512, do_sample=False)
+print(tokenizer.decode(output[0], skip_special_tokens=True))
+```
+
+## Limitations
+
+- Trained on a single epoch of a 5k-example subset — not intended to be a general-purpose assistant.
+- MMLU/ARC/HellaSwag/WinoGrande scores reflect a small 1B-parameter base model and should be read relative to
+  the base model's own scores, not against much larger models.
+- No safety alignment or RLHF was applied beyond what the base Llama-3.2-1B already has.
