 Grounded SAM 2 does not introduce significant methodological changes compared to [Grounded SAM: Assembling Open-World Models for Diverse Visual Tasks](https://arxiv.org/abs/2401.14159). Both approaches leverage the capabilities of open-world models to address complex visual tasks. Consequently, we try to **simplify the code implementation** in this repository, aiming to enhance user convenience.
 
 ## Latest updates
+- **2025.04.20**: Update to `dds-cloudapi-sdk` API V2 version. The V1 version in the original API for `Grounding DINO 1.5` and `DINO-X` has been deprecated, please update to the latest `dds-cloudapi-sdk` by `pip install dds-cloudapi-sdk -U` to use `Grounding DINO 1.5 / 1.6` and `DINO-X` models. Please refer to [dds-cloudapi-sdk](https://github.com/deepdataspace/dds-cloudapi-sdk) and our [API docs](https://cloud.deepdataspace.com/docs) to view more details about the update.
 
 - **2024.12.02**: Support **DINO-X with SAM 2** demos (including object segmentation and tracking), please install the latest version of `dds-cloudapi-sdk==0.3.3` and refer to [Grounded SAM 2 (with DINO-X)](#grounded-sam-2-image-demo-with-dino-x) and [Grounded SAM 2 Video (with DINO-X)](#grounded-sam-2-video-object-tracking-demo-with-custom-video-input-with-dino-x) for more details.
