On September 25, as reported by Wall Street Insights citing Machine Heart, DeepSeek Harness has launched its official desktop version, which supports a graphical interface, DeepSeek account login, and API Key, significantly lowering the usage threshold compared to the previous web version that required command line initiation. This client has passed Apple notarization, with the signing entity being 'Hangzhou DeepSeek Artificial Intelligence Co., Ltd', pointing to DeepSeek company, but it is a nightly build and has not been officially announced. The version includes six official plugins (Agent Team, Voice Input, Terminal, Agent Loop, Subagent, Web Search) and offers four working modes: Standard, PTC, Minimalist, and Creative, continuing the composable architecture concept of 'Everything is a Plugin'. Currently, this client does not support Linux.
