+# VCoder
+VCoder is a Python-focused coding assistant fine-tuned from Qwen2.5-Coder-3B-Instruct using LoRA and Unsloth.
+The model was trained on 15,000 Python instruction-response examples from the Python Code Instructions 15K dataset and optimized for Python code generation, problem solving, debugging, and algorithm implementation.
 ## Model Details
+| Attribute | Value |
+|------------|---------|
+| Base Model | Qwen2.5-Coder-3B-Instruct |
+| Fine-Tuning Method | LoRA |
+| Framework | Unsloth |
+| Dataset | Python Code Instructions 15K |
+| Training Samples | 15,000 |
+| GPU | NVIDIA Tesla T4 |
+| Quantized Format | GGUF Q8_0 |
+| Primary Language | Python |
+---
+## Training Pipeline
+Training was performed incrementally:
+| Stage | Samples |
+|---------|---------|
+| Stage 1 | 0 - 5,000 |
+| Stage 2 | 5,000 - 10,000 |
+| Stage 3 | 10,000 - 15,000 |
+The model was trained using parameter-efficient fine-tuning (LoRA), allowing adaptation of the base model while keeping computational requirements low.
+---
+## Benchmark Results
+![Output](https://cdn-uploads.huggingface.co/production/uploads/6a297050d3837ea7b12cc42f/BV8FY6fJN7KQ43jcpC6hr.png)
+### HumanEval Comparison
+The model was evaluated against the original Qwen2.5-Coder-3B-Instruct on HumanEval coding tasks.
+| Model | Pass@1 |
+|---------|---------|
+| Base Qwen2.5-Coder-3B | 61.0% |
+| VCoder | 68.0% |
+### Improvement
+```text
++7.0% Pass@1 improvement
+```
+This demonstrates that the fine-tuned model performs better on Python coding tasks than the original base model.
+---
+## Example Usage
+### Python
+```python
+prompt = """
+### Instruction:
+Write a Python function to reverse a string.
+### Input:
+### Response:
+"""
+```
+### Example Output
+```python
+def reverse_string(text):
+    return text[::-1]
+```
+---
+## Supported Tasks
+- Python Code Generation
+- Algorithm Design
+- Data Structures
+- Debugging
+- Code Refactoring
+- Coding Interview Questions
+- Competitive Programming
+- Function Completion
+---
+## GGUF Usage
+Compatible with:
+- Ollama
+- LM Studio
+- llama.cpp
+- Open WebUI
+- Jan
+### Ollama
+Create a Modelfile:
+```text
+FROM ./VCoder.Q8_0.gguf
+```
+Build:
+```bash
+ollama create vcoder -f Modelfile
+```
+Run:
+```bash
+ollama run vcoder
+```
+---
+## Training Dataset
+Dataset used:
+Python Code Instructions 15K
+The dataset contains instruction-response pairs focused on Python programming tasks including:
+- Function generation
+- Data manipulation
+- Algorithms
+- Debugging
+- Problem solving
+---
+## Limitations
+- Primarily optimized for Python.
+- Benchmark performed on a subset of HumanEval tasks.
+- May generate incorrect code for highly specialized domains.
+- Should not be used as the sole source of production-critical code.
