tencent-WeVisOne-VL-2B-GGUF

WeVisOne-VL-2B (tencent/WeVisOne-VL-2B) is an open-weight 2B-parameter vision-language model from Tencent WeChat Vision, released under Apache-2.0 as a compact member of the WeVisOne-VL series built on Qwen3-VL. It unifies object-level perception, including open-vocabulary detection, referring expression localization, counting, point grounding, and OCR, with pixel-level tasks such as referring segmentation and promptable alpha matting. Using structured next-token prediction without explicit chain-of-thought reasoning, it encodes normalized coordinates with dedicated tokens (<0> to <1000>), returns None for absent targets, and uses <OBJ> tokens to support dense prediction. Its lightweight 9.5M–9.6M-parameter pixel decoder combines multi-level visual features, box-guided deformable attention, and progressive dense prediction to generate full-resolution alpha mattes. Trained on approximately 100 million finely annotated images through a three-stage supervised fine-tuning curriculum followed by mixed-task reinforcement learning, the model has an approximate 4.9 GB footprint in BF16. It supports object detection, grounding, counting, OCR, segmentation, and matting; no benchmark scores were provided in the supplied description. Deployment is available through the wevisone_vl Python package, Hugging Face Transformers, vLLM, and SGLang.
