IconShop SVG Icon Generator

⚠️ ALPHA / RESEARCH PREVIEW — NOT PRODUCTION READY This is alpha work. It is not production ready. This model is published as a starting point for people who want to get into the business of model training. The output quality is inconsistent, and you should expect broken or malformed SVGs. Treat this as an educational/demo artifact — not something to ship.

A custom autoregressive transformer model that generates SVG icons from text descriptions.

Example outputs

Model Description

This model is trained on the FIGR-8-SVG dataset using the IconShop architecture - an autoregressive transformer that predicts SVG vector commands token-by-token, conditioned on a text prompt.

Architecture:

• —Transformer decoder with 16 layers, 8 attention heads
• —Hidden dimension: 1024, Embedding dimension: 512
• —BERT uncased tokenizer for text conditioning (50 token max)
• —Pixel sequence length: 512
• —SVG bounding box: 200x200

Training:

• —Dataset: FIGR-8-SVG (1.5M cleaned SVG icons)
• —5 epochs on 4x NVIDIA RTX 3090
• —Training loss: 2.01 (pixel loss: 2.17, text loss: 0.88)

Usage

Installation

pip install torch transformers safetensors deepsvg cairosvg

# Load weights
from safetensors.torch import load_file
state_dict = load_file(model_path)
model.load_state_dict(state_dict, strict=False)
model.eval()

Command-line usage

# Single prompt
python model_card.py --output ./samples --prompts "star"

# Multiple prompts
python model_card.py --output ./samples --prompts "star" "calendar" "car"

Limitations

• —Generates icons in 200x200 bounding box
• —Best results for simple, common icon types (arrows, stars, animals, UI elements)
• —Complex scenes or abstract concepts may produce degraded output
• —Trained on simplified SVG format (not all SVG features supported)
• —Output quality varies significantly between samples
