-## 🚀 Introduction
-StarVector is a multimodal vision-language model for Scalable Vector Graphics (SVG) generation. It can be used to perform image2SVG and text2SVG generation. We pose image generation as a code generation task, using the power of multimodal VLMs

-> **Abstract**: Scalable Vector Graphics (SVGs) are vital for modern image rendering due to their scalability and versatility. Previous SVG generation methods have focused on curve-based vectorization, lacking semantic understanding, often producing artifacts, and struggling with SVG primitives beyond \textit{path} curves. To address these issues, we introduce StarVector, a multimodal large language model for SVG generation. It performs image vectorization by understanding image semantics and using SVG primitives for compact, precise outputs. Unlike traditional methods, StarVector works directly in the SVG code space, leveraging visual understanding to apply accurate SVG primitives. To train StarVector, we create SVG-Stack, a diverse dataset of 2M samples that enables generalization across vectorization tasks and precise use of primitives like ellipses, polygons, and text. We address challenges in SVG evaluation, showing that pixel-based metrics like MSE fail to capture the unique qualities of vector graphics. We introduce SVG-Bench, a benchmark across 10 datasets, and 3 tasks: Image-to-SVG, Text-to-SVG generation, and diagram generation. Using this setup, StarVector achieves state-of-the-art performance, producing more compact and semantically rich SVGs.
-### Multimodal Architecture
-StarVector uses a multimodal architecture to process images and text. When performing Image-to-SVG (or image vectorization), the image is projected into visual tokens, and SVG code is generated. When performing Text-to-SVG, the model only recieves the text instruction (no image is provided), and a novel SVG is created. The LLM is based of StarCoder, which we leverage to transfer coding skills to SVG generation.

->We offer a summary of statistics about the datasets used in our training and evaluation experiments. This datasets are included in SVG-Bench. The subscript _sim_ stands for the simplified version of the dataset, as required by some baselines.
-## Training
-### Confirm dependencies are installed
-```bash
-pip install -e ".[train]"
-```
-### Set environment variables
-We recommend setting the following environment variables:
-```bash
-  export HF_HOME=<path to the folder where you want to store the models>
-  export HF_TOKEN=<your huggingface token>
-  export WANDB_API_KEY=<your wandb token>
-  export OUTPUT_DIR=<path/to/output>
-```
-cd the root of the repository.
-```Shell
-cd star-vector
-```
-### Image2SVG Pretraining (Stage 1)
-We have different training approaches for StarVector-1B and StarVector-8B. StarVector-1B can be trained using Deepspeed, while StarVector-8B requires FSDP.
-#### StarVector-1B Training
-You can use the following command to train StarVector-1B on SVG-Stack for the Image2SVG vectorization task, using Deepspeed and Accelerate
-```bash
-# StarVector-1B
-accelerate launch --config_file configs/accelerate/deepspeed-8-gpu.yaml starvector/train/train.py config=configs/models/starvector-1b/im2svg-stack.yaml
-```
-#### StarVector-8B Training
-You can use the following command to train StarVector-8B on SVG-Stack for the Image2SVG vectorization task, using FSDP and Accelerate. We provide the torchrun command to support multi-nodes and multi-GPUs.
-```bash
-# StarVector-8B
-torchrun \
-  --nproc-per-node=8 \
-  --nnodes=1 \
-  starvector/train/train.py \
-  config=configs/models/starvector-8b/im2svg-stack.yaml
-```
-### Finetuning StarVector (Stage 2)
-After pretraining StarVector on image vectorization, we finetune it on additional SVG tasks like Text2SVG, and SVG-Bench datasets.
-#### Text2SVG Finetuning
-```bash
-# StarVector-1B
-accelerate launch --config_file config/accelerate/deepspeed-8-gpu.yaml starvector/train/train.py config=configs/models/starvector-1b/text2svg-stack.yaml
-# StarVector-8B
-torchrun \
-  --nproc-per-node=8 \
-  --nnodes=1 \
-  starvector/train/train.py \
-  config=configs/models/starvector-8b/text2svg-stack.yaml
-```
-#### SVG-Bench Finetuning
-```bash
-# StarVector-1B
-accelerate launch --config_file config/accelerate/deepspeed-8-gpu.yaml starvector/train/train.py config=configs/models/starvector-1b/im2svg-{fonts,icons,emoji}.yaml
-# StarVector-8B
-torchrun \
-  --nproc-per-node=8 \
-  --nnodes=1 \
-  starvector/train/train.py \
-  config=configs/models/starvector-8b/im2svg-{fonts,icons,emoji}.yaml
-```
-We also provide shell scripts in `scripts/train/*`
-## Validation on SVG Benchmarks (⭐ SVG-Bench)
-We validate StarVector on ⭐ SVG-Bench Benchmark. We provide the SVGValidator class that allows you to run StarVector using **1) the HuggingFace generation backend** or **2) the VLLM backend**. The later is substantially faster thanks to the use of Paged Attention.
-### HuggingFace Generation Backend
-Let's start with the evaluation for StarVector-1B and StarVector-8B on SVG-Stack, using the HuggingFace generation backend (StarVectorHFAPIValidator). To override the input arguments, you can add cli args following the yaml file structure.
-```bash
-# StarVector-1B on SVG-Stack, using the HuggingFace backend
-python starvector/validation/validate.py \
-config=configs/generation/hf/starvector-1b/im2svg.yaml \
-dataset.name=starvector/svg-stack
-# StarVector-8B on SVG-Stack, using the vanilla HuggingFace generation API
-python starvector/validation/validate.py \
-config=configs/generation/hf/starvector-8b/im2svg.yaml \
-dataset.name=starvector/svg-stack
-```
-### vLLM Backend
-For using the vLLM backend (StarVectorVLLMAPIValidator), first install our StarVector fork of VLLM, [here](https://github.com/starvector/vllm).
-```bash
-git clone https://github.com/starvector/vllm.git
-cd vllm
-pip install -e .
-```
-Then, launch the using the vllm config file (it uses StarVectorVLLMValidator):
-```bash
-# StarVector-1B
-python starvector/validation/validate.py \
-config=configs/generation/vllm/starvector-1b/im2svg.yaml \
-dataset.name=starvector/svg-stack
-# StarVector-8B
-python starvector/validation/validate.py \
-config=configs/generation/vllm/starvector-8b/im2svg.yaml \
-dataset.name=starvector/svg-stack
-```
-#### Generate using Temperature Sweep
-Temperature sweep is an evaluation technique where we:
-1. Generate multiple SVG candidates using different temperature values (controlling randomness in generation)
-2. Evaluate each candidate using the DinoScore metric
-3. Select the best performing SVG as the final output
-This approach improves result quality by exploring multiple generation possibilities, though it requires more computation time.
-```bash
-# StarVector-1B (vLLM)
-python starvector/validation/run_validator.py \
-config=configs/generation/vllm/starvector-1b/im2svg.yaml \
-dataset.name=svg-stack \
-generation_params.generation_sweep=True \
-generation_params.num_generations_different_temp=5 \
-generation_params.min_temperature=0.0 \
-generation_params.max_temperature=0.5
-# StarVector-8B (vLLM)
-python starvector/validation/run_validator.py \
-config=configs/generation/vllm/starvector-8b/im2svg.yaml \
-dataset.name=svg-stack \
-generation_params.generation_sweep=True \
-generation_params.num_generations_different_temp=10 \
-generation_params.min_temperature=0.0 \
-generation_params.max_temperature=0.5
-```
-We provide evaluation scripts in `scripts/eval/*`
-## StarVector Demo
-The demo provides two options for converting images to SVG code:
-1. HuggingFace generation functionality
-2. VLLM (recommended) - offers faster generation speed
-### Option 1: HuggingFace Generation with Gradio Web UI
-We provide a Gradio web UI for you to play with our model.
-#### Launch a controller
-```Shell
-python -m starvector.serve.controller --host 0.0.0.0 --port 10000
-```
-#### Launch a gradio web server.
-```Shell
-python -m starvector.serve.gradio_web_server --controller http://localhost:10000 --model-list-mode reload --port 7000
-```
-You just launched the Gradio web interface. Now, you can open the web interface with the URL printed on the screen. You may notice that there is no model in the model list. Do not worry, as we have not launched any model worker yet. It will be automatically updated when you launch a model worker.
-#### Launch a model worker
-This is the actual *worker* that performs the inference on the GPU.  Each worker is responsible for a single model specified in `--model-path`.
-```Shell
-python -m starvector.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path joanrodai/starvector-1.4b
-```
-Wait until the process finishes loading the model and you see "Uvicorn running on ...".  Now, refresh your Gradio web UI, and you will see the model you just launched in the model list.
-You can launch as many workers as you want, and compare between different model checkpoints in the same Gradio interface. Please keep the `--controller` the same, and modify the `--port` and `--worker` to a different port number for each worker.
-```Shell
-vllm serve starvector/starvector-8b-im2svg --chat-template configs/chat-template.jinja --trust-remote-code --port 8001 --max-model-len 16000
-python -m starvector.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port <different from 40000, say 40001> --worker http://localhost:<change accordingly, i.e. 40001> --model-path <ckpt2>
-```
-#### Option 2: Launch VLLM
-0. Remember to clone the starvector/vllm fork (it has modifications for starvector).
-```Shell
-git clone https://github.com/starvector/vllm.git
-cd vllm
-pip install -e .
-```
-1. Call this to launch the VLLM endpoint
-```Shell
-vllm serve starvector/starvector-1b-im2svg --chat-template configs/chat-template.jinja --trust-remote-code --port 8000 --max-model-len 8192
-```
-2. Create the demo for VLLM
-```Shell
-python -m starvector.serve.vllm_api_gradio.controller --host 0.0.0.0 --port 10000
-python -m starvector.serve.vllm_api_gradio.gradio_web_server --controller http://localhost:10000 --model-list-mode reload --port 7000
-python -m starvector.serve.vllm_api_gradio.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-name starvector/starvector-1b-im2svg --vllm-base-url http://localhost:8000
-```
-3. Add more models by serving them with VLLM and calling a new model worker
-```Shell
-vllm serve starvector/starvector-8b-im2svg --chat-template configs/chat-template.jinja --trust-remote-code --port 8001 --max-model-len 16384
-python -m starvector.serve.vllm_api_gradio.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40001 --worker http://localhost:40001 --model-name starvector/starvector-8b-im2svg --vllm-base-url http://localhost:8001
