On November 3, 2026, DeepSeek launched Creator Mode for its open-source agent platform DeepSeek Harness, allowing users to describe their needs in natural language and the agent to write, install, and run plugins on the spot. Phoenix Technology reported that in an official demo, a single-line request completed the construction, installation, and verification of a floating Pomodoro timer plugin in about five and a half minutes; the platform is based on Cordis's "everything is a plugin" architecture, and the official release also included seven demo cases—including a landmark 3D gallery, a Transformer 3D visualization, a video editing workbench, and a paper reader—along with Chinese and English prompts. 36Kr · AI tested it the same day and reported that using a prompt of about 100 characters, it created two plugins—a 3D Mario mini-game and a desktop pet—at a total cost of about 6 yuan, with a 99% cache hit rate, but the generation process required multiple clicks on "Allow"; DeepSeek acknowledged that some demos require multiple rounds of refinement, that the project is still in the developer preview stage, that core plugins and APIs may undergo breaking changes, and that there is currently no official plugin marketplace.

Hands-on with DeepSeek Harness Creation Mode: Generating Plugins with Natural Language
DeepSeek released DSH Creation Mode on November 2. Users describe their ideas in natural language, and the Agent writes the code, packages it, and installs it as a plugin that DSH can use directly. The company also released 7 demos along with Chinese and English prompts. In the author's hands-on test, prompts of about 100 characters were used to create two plugins—a 3D Mario mini-game and a desktop pet—at a total cost of about 6 yuan, with a 99% cache hit rate, though the generation process required multiple clicks on "Allow." DeepSeek acknowledges that some demos require multiple rounds of refinement, that the project is still in developer preview, that core plugins and APIs may undergo breaking changes, and that there is currently no official plugin marketplace.

DeepSeek Harness releases a Creator Mode guide, publishing 7 plugin prompts
DeepSeek Harness officially releases a "Creator Mode" gameplay guide; users can select Creator Mode in a session and use a single sentence to have the Agent write and run a plugin. The official team also published 7 example prompts, covering a 3D architectural model, an interactive demonstration of the Transformer computation process, a video editing workbench, a poster design workbench, a paper reader, interface skinning, and a token billing board. The official team notes that some demo plugins were modified through multiple rounds of dialogue, so a single prompt may not fully reproduce the video results.
