🏠 Project Page | 📖 Paper | 💻 GitHub | 🤗 VisCode2
VisCoder2-14B is a lightweight multi-language visualization coding model trained for executable code generation, rendering, and iterative self-debugging .
🧠 Model Description
VisCoder2-14B is trained on the VisCode-Multi-679K dataset, a large-scale instruction-tuning dataset for executable visualization tasks across 12 programming language . It addresses a core challenge in multi-language visualization: generating code that not only executes successfully but also produces semantically consistent visual outputs by aligning natural-language instructions and rendering results.
📊 Main Results on VisPlotBench
We evaluate VisCoder2-14B on VisPlotBench , which includes 888 executable visualization tasks spanning 8 languages, supporting both standard generation and multi-turn self-debugging.
VisCoder2-14B shows consistent performance across multiple languages and achieves notable improvements under the multi-round self-debug setting.
📁 Training Details
- Base model : Qwen2.5-Coder-14B-Instruct
- Framework : ms-swift
- Tuning method : Full-parameter supervised fine-tuning (SFT)
- Dataset : VisCode-Multi-679K
