Breaking: DeepSeek Harness has released the desktop version

Author: Machine Heart

DeepSeek Harness finally has an official desktop version?

This time, DeepSeek did not issue an announcement, but the related download link has already spread on social media:

We opened the link, downloaded, and installed it, and found that it indeed works.

From the interface, it is already a quite complete GUI: open the app, log in to your DeepSeek account or add an API Key, select a local folder as the workspace, and then you can assign tasks to the Agent just like using a regular desktop AI application.

Subsequently, Harness will let users choose their usage direction. It roughly categorizes needs into office research, code development, and other categories.

Next, it will also ask users which workflow they prefer.

DeepSeek has also prepared several "working modes" for the Agent: Standard Mode, PTC Mode, Minimal Mode, and Creative Mode.

Standard Mode is suitable for most tasks and is likely the easiest way for ordinary users to understand how to use Harness.

PTC is a bit more technical, allowing the model to write a small piece of code first, and then organize and call tools in bulk through the program, which is especially suitable for batch processing.

Minimal Mode is even simpler and more straightforward, where the Agent only uses terminal tools to complete tasks, which is closer to traditional Coding Agents and very direct for developers familiar with the command line.

Creative Mode allows the Agent to write plugins, add new features or interfaces, and also combine tools and prompts to create its own modes. This aligns with the design philosophy that DeepSeek Harness emphasized from the beginning—officially summarizing its architecture as Everything is a Plugin, meaning that the capabilities of Harness are designed to be as composable and extensible as possible.

From the current interface, DeepSeek Harness has already built-in 6 official plugins, including Agent Team, Voice Input, Terminal, Agent Loop, Subagent, and Web Search. Among them, "Agent Team" and "Voice Input" are currently marked as "experimental," with the former used to enable multi-Agent collaboration, supporting team tools, member lists, and shared task boards; the latter can call SenseVoice on the local machine to convert voice directly into text, but requires additional dependencies to be installed for first-time use.

The other plugins are closer to the core capabilities of Harness. The Terminal is responsible for calling local command lines and can limit the maximum runtime and output of a single command; the Agent Loop controls how the Agent calls tools in rounds and continues executing tasks; the Subagent allows setting the recursive level, number, and model used for sub-Agents, effectively allowing one Agent to spawn multiple "assistants" to handle sub-tasks; the Web Search is used to configure DeepSeek's own search provider.

Overall, this already resembles an AI product aimed at ordinary users.

Previously, although DeepSeek Harness provided a Web UI, the officially recommended way to start was still to install Node.js first, and then enter a command in the terminal: npx @deepseek-ai/dsh web. Harness would start a local service and then open a browser page. For developers, this is not complicated. But for many who are not familiar with the command line, it always carried a strong "developer tool" flavor. With the release of the desktop version, the usage threshold has been greatly lowered.

However, under the related news, the most debated topic is: is this the official version?

We found a discussion thread on GitHub. This thread is asking when the DeepSeek "official desktop client will be released."

A user named "overFloweee" replied that: there is actually already a product (just not officially announced).

The information he provided was very specific, checking the download source, version number, installation package, signature, and official website status. One key piece of information is that this App is signed with the Apple developer certificate corresponding to DeepSeek's main entity and has also undergone Apple's notarization. Its signing entity, Hangzhou DeepSeek Artificial Intelligence Co., Ltd., directly points to DeepSeek.

But he also pointed out: DeepSeek has not officially announced it yet. This version is on the nightly channel, more like a candidate build that has entered the official production distribution system, and cannot be directly equated with "the official stable version has been released."

Therefore, many of the features mentioned above may still be immature.

We also ran some commands in this client to verify and found some key information mentioned by the above user.

Currently, the community has already provided some preliminary experience evaluations:

Interestingly, we just successfully installed it based on the address circulated in the community, and it already prompted that a new version is available, indicating that the team is rapidly iterating.

However, this client currently does not support Linux, thus creating a world where only Linux users are left out.
