ByteDance Open Sources Seed-X 7B: A Compact Translation Model Supporting 28 Languages
In July 2025, ByteDance officially open-sourced the Seed-X 7B model. This model is specifically designed for multilingual translation tasks, featuring only 7 billion parameters while supporting translation between 28 major languages, including Chinese, English, French, Japanese, Korean, and more. According to official benchmark tests, the translation performance of Seed-X 7B is comparable to larger models such as DeepSeek R1 and Gemini Pro 2.5.
Highlights of Seed-X 7B
- Efficient and lightweight: With only 7B parameters, it is easy to deploy locally and for inference, requiring low resources.
- Multilingual support: Covers 28 major languages, suitable for translation needs in various fields such as the internet, technology, office, healthcare, finance, law, literature, and entertainment.
- Excellent translation performance: Performs well in authoritative benchmarks like FLORES-200 and WMT-25, and has received high recognition in human evaluations.
- Open-source friendly: Uses an open license (OpenMDW), making it convenient for community and enterprise integration and secondary development.
Using Seed-X 7B in ComfyUI
To facilitate multilingual integration in scenarios such as AI image generation, the community has developed a custom ComfyUI node for Seed-X 7B. After installation, the plugin will automatically download the required model, allowing users to easily use Seed-X for text translation within ComfyUI workflows, greatly improving the efficiency of multilingual workflows (workflow).
