# Drawing with LLM 🎨

A Streamlit application that converts text descriptions into SVG graphics using multiple AI models.

Access demo app by this [link](https://huggingface.co/spaces/Timxjl/text2svg-demo-app)

## Overview

This project allows users to create vector graphics (SVG) from text descriptions using three different approaches:
1. **ML Model** - Uses Stable Diffusion to generate images and vtracer to convert them to SVG
2. **DL Model** - Uses Stable Diffusion for initial image creation and StarVector for direct image-to-SVG conversion
3. **Naive Model** - Uses Phi-4 LLM to directly generate SVG code from text descriptions

## Features

- Text-to-SVG generation with three different model approaches
- Adjustable parameters for each model type
- Real-time SVG preview and code display
- SVG download functionality
- GPU acceleration for faster generation

## Requirements

- Python 3.11+
- CUDA-compatible GPU (recommended)
- Dependencies listed in `requirements.txt`

## Installation

### Using Miniconda (Recommended)

```bash
# Install Miniconda
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh
bash miniconda.sh -b -p $HOME/miniconda
echo 'export PATH="$HOME/miniconda/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

# Create and activate environment
conda create -n svg-app python=3.11 -y
conda activate svg-app

# Install star-vector
cd star-vector 
pip install -e .
cd ..

# Install other dependencies
pip install -r requirements.txt
```

### Using Docker

```bash
# Build and run with Docker Compose
docker-compose up -d
```

## Usage

Start the Streamlit application:

```bash
streamlit run app.py
```

Or with the yes flag to automatically accept:

```bash
yes | streamlit run app.py
```

The application will be available at http://localhost:8501

## Models

### ML Model (vtracer)
Uses Stable Diffusion to generate an image from the text prompt, then applies vtracer to convert the raster image to SVG.

Configurable parameters:
- Simplify SVG
- Color Precision
- Filter Speckle
- Path Precision

### DL Model (starvector)
Uses Stable Diffusion for initial image creation followed by StarVector, a specialized model designed to convert images directly to SVG.

### Naive Model (phi-4)
Directly generates SVG code using the Phi-4 language model with specialized prompting.

Configurable parameters:
- Max New Tokens

## Evaluation Data and Results

### Data
The `data` directory contains synthetic evaluation data created using custom scripts:
- The first 15 examples are from the Kaggle competition "Drawing with LLM"
- `descriptions.csv` - Text descriptions for generating SVGs
- `eval.csv` - Evaluation metrics
- `gen_descriptions.py` - Script for generating synthetic descriptions
- `gen_vqa.py` - Script for generating visual question answering data
- Sample images (`gray_coat.png`, `purple_forest.png`) for reference

### Results
The `results` directory contains evaluation results comparing different models:
- Evaluation results for both Naive (Phi-4) and ML (vtracer) models
- The DL model (StarVector) was not evaluated as it typically fails on transforming natural images, often returning blank SVGs
- Performance visualizations:
  - `category_radar.png` - Performance comparison across categories
  - `complexity_performance.png` - Performance relative to prompt complexity
  - `quality_vs_time.png` - Quality-time tradeoff analysis
  - `generation_time.png` - Comparison of generation times
  - `model_comparison.png` - Overall model performance comparison
- Generated SVGs and PNGs in respective subdirectories
- Detailed results in JSON and CSV formats
