+# llama-3.2-1b-instruct-code-translation
+
+A fine-tuned version of [meta-llama/Llama-3.2-1B-Instruct](https://huggingface.co/meta-llama/Llama-3.2-1B-Instruct) for translating code between **C++**, **Java**, and **Python**.
+
+## Training
+
+- **Base model:** meta-llama/Llama-3.2-1B-Instruct
+- **Method:** LoRA (Low-Rank Adaptation) via [LLaMA-Factory](https://github.com/hiyouga/LLaMA-Factory)
+- **Dataset:** [tkeskin/leetcode-solutions](https://huggingface.co/datasets/tkeskin/leetcode-solutions) (`instruct` config) — directed C++/Java/Python translation pairs derived from LeetCode solutions
+- **Hardware:** AMD MI210 (ROCm) / NVIDIA CUDA, `flash_attn: sdpa`
+- **LoRA target:** all linear layers (`lora_target: all`)
+- **Precision:** bf16
+
+## Evaluation
+
+Evaluated with an **execution-based** translation benchmark: each held-out `evaluation`-config payload from [tkeskin/leetcode-solutions](https://huggingface.co/datasets/tkeskin/leetcode-solutions) is a directed source→target translation whose output is compiled and run against the problem's input/output pairs. The eval split is held out from training (no leakage). Metric is **pass@1** (all test cases pass), n-weighted over 3,336 payloads.
+
+| | Base (Llama-3.2-1B-Instruct) | This model | Δ |
+|---|---|---|---|
+| **pass@1** | 17.5% | **32.5%** | **+15.0** |
+| **compile rate** | 52.8% | **72.7%** | **+19.8** |
+
+pass@1 by language pair × difficulty (%):
+
+| source | target | difficulty | base | this model |
+|---|---|---|---|---|
+| cpp | java | Easy | 29.0 | 55.9 |
+| cpp | java | Hard | 7.6 | 24.6 |
+| cpp | java | Medium | 15.9 | 39.5 |

+| python | java | Easy | 24.1 | 30.3 |
+| python | java | Hard | 3.4 | 7.6 |
+| python | java | Medium | 12.4 | 19.4 |
+
+Full methodology is in the [llm-fine-tune](https://github.com/tkeskin/llm-fine-tune) repo (Stage 5).
+
+## Intended use
+
+Given source code in one of C++, Java, or Python, the model generates a translation into the target language, following the same logic and structure.
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "tkeskin/llama-3.2-1b-instruct-code-translation"
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id)
+
+messages = [
+    {
+        "role": "user",
+        "content": "Translate the following C++ code to Python:\n\nint add(int a, int b) { return a + b; }"
+    }
+]
+inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
+outputs = model.generate(inputs, max_new_tokens=256)
+print(tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True))
+```
