DeepSeek has launched Harness v0.2, a desktop application designed for coding and work tasks. The software transitioned from a developer preview, which was released on August 13, 2026, to a full desktop version on September 29, 2026.
The application functions as an open-source runtime under the MIT license. It supports file organization, data analysis, and coding. Users can expand functionality through plugins. The tool connects to the DeepSeek-V4.1-Flash model, requiring an account or API keys for operation.
Official builds are available for macOS and Windows. Linux support is currently provided through community-developed builds. As of early October 2026, the Harness repository on GitHub reached approximately 242,000 stars and 29,000 forks.
Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. was founded in July 2023 by Liang Wenfeng. The company is known for its open-weight large language models, which reportedly require lower investment compared to Western counterparts.
