Key point

Built on Qwen3-VL, WeVisOne-VL uses a 9.6M-parameter pixel decoder to unify object-level and pixel-level perception tasks.

Details

  • Tencent WeChat Vision developed WeVisOne-VL, a unified vision-language model built upon Qwen3-VL.
  • The model integrates object-level perception (open-vocabulary object detection, referring localization, object counting, object pointing, OCR) and pixel-level perception (referring segmentation and promptable alpha matting).
  • The architecture relies on structured next-token prediction and a lightweight 9.6M-parameter pixel decoder.
  • The model is available on Hugging Face, with the provided evidence linking to the tencent/WeVisOne-VL-2B repository.
