[DeepSeek Harness Launches Official Desktop Version, Apple Notarization Approved but Not Yet Officially Announced] According to a report by Jinse Finance on September 25, citing Machine Heart via Wall Street Insights, DeepSeek Harness has launched its official desktop version. This version 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 startup. The client has passed Apple notarization, with the signing entity listed as 'Hangzhou DeepSeek Artificial Intelligence Co., Ltd,' pointing to DeepSeek, but it is a nightly version and has not been officially announced. The version comes with six built-in official plugins (Intelligent 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, the client does not support Linux.
