We are the InternSVG team from the Shanghai AI Laboratory, dedicated to empowering the InternVL series models with unified capabilities for SVG vector graphic understanding, editing, and generation.

Current Work: 

## InternSVG: Towards Unified SVG Tasks with Multimodal Large Language Models

The InternSVG Family — a comprehensive suite that unifies data, benchmarks, and models for SVG understanding, editing, and generation. It consists of:

🧩 SAgoge — the largest and most diverse multimodal SVG dataset, covering icons, illustrations, chemistry diagrams, and dynamic animations;

🏆 SArena — a companion benchmark offering unified task definitions and standardized evaluation protocols across SVG domains;

🤖 InternSVG Models — multimodal large language models trained for SVG understanding, editing, and generation.

## Reliable Reasoning in SVG-LLMs via Multi-Task Multi-Reward Reinforcement Learning

In this work, we present CTRL-S (Chain-of-Thought Reinforcement Learning for SVG), a unified framework that introduces a chain-of-thought mechanism to explicitly expose the model’s reasoning process during SVG generation. To support this structured reasoning, we construct SVG-Sophia, a high-quality dataset of 145K samples across SVG code refinement, Text-to-SVG, and Image-to-SVG tasks. Furthermore, we design a robust multi-reward reinforcement learning scheme powered by the GRPO algorithm. By jointly optimizing across DINO, image-text similarity, format, and code efficiency rewards in a multi-task setting, our approach systematically boosts structural coherence and generation capabilities. Extensive experiments show that CTRL-S outperforms existing methods, achieving higher task success rates, superior code quality, and exceptional visual fidelity.
