According to CoinMeta, DeepSeek showcases the creator mode of Harness ( creator mode ), which allows users to simply describe their needs so that AI can develop plugins, modify software interfaces, and directly install them for use within Harness without the need to write any code. Users can create video editing tools, readers with line drawing and annotation support, poster design tools, interactive 3D models, and even modify the interface style of Harness. In an official demonstration, AI created a floating tomato clock by writing just over 600 lines of front-end code, which took 5 minutes and 24 seconds. DeepSeek also made available prompts for 7 demonstration cases.
