+# Saikrishna2511/java2py-qwen
+
+Java→Python fine-tuned **Qwen2.5-Coder-0.5B-Instruct** checkpoint (Stage 1 LoRA, merged for inference).
+
+## Demo
+
+Related multi-task demo: [https://huggingface.co/spaces/Saikrishna2511/qwen-multitask-demo](https://huggingface.co/spaces/Saikrishna2511/qwen-multitask-demo)
+
+## Task
+
+### Java → Python (`java2py`)
+
+```
+### Translate Java to Python:
+```java
+{java code}
+```
+### Python:
+```python
+```
+
+## Training
+
+- **Base model:** [Qwen/Qwen2.5-Coder-0.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-0.5B-Instruct)
+- **Data:** AVATAR-TC / Java→Python pairs
+- **Method:** LoRA (r=16, alpha=32), merged weights for inference
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+model_id = "Saikrishna2511/java2py-qwen"
+tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    trust_remote_code=True,
+    torch_dtype=torch.float16,
+    device_map="auto",
+)
+
+java = "public class Hello { public static void main(String[] args) { System.out.println(\"hi\"); } }"
+prompt = f"### Translate Java to Python:\\n```java\\n{java}\\n```\\n### Python:\\n```python\\n"
+inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.2, top_p=0.95)
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+```
+
+## Limitations
+
+- Small 0.5B model; translation quality varies with input complexity
+- Prefer the multi-task checkpoint for NL→Python / Code2Doc: [Saikrishna2511/qwen-multitask](https://huggingface.co/Saikrishna2511/qwen-multitask)
+- Not intended for production use without further evaluation
