Tencent open-sources WeVisOne-VL for all-in-one vision tasks
Tencent's WeChat Vision Team just open-sourced WeVisOne-VL, an all-in-one vision model in 2B and 4B sizes that unifies detection, counting, OCR, and matting. It ditches heavy external segmentation models like SAM in favor of a tiny 9.6M-parameter decoder, generating hair-level alpha mattes while reliably rejecting absent targets. Weights and code are out under Apache 2.0.
