DeepSeek Harness new Creator Mode creates plugins from prompts

DeepSeek added a Creator Mode to its open-source DeepSeek Harness that generates plugins directly from text prompts, the company announced. DeepSeek demonstrated AI-generated plugins including a digital sticky note wall, a poster design tool and a Minecraft-like video game, and published the demonstration prompts in English and Chinese, though it cautioned that "some plugins were refined through several rounds of conversation, so a single prompt may not reproduce exactly what you see in the video." Harness is built on the principle that "everything is a plugin," connecting large language models to tools and systems so they can perform actions.

DeepSeek Harness has added a new Creator Mode, which aims to create plugins directly from text prompts.

While AI models are capable of generating responses to prompts and determining a course of action, actually carrying it out requires a harness. Harnesses connect large language models (LLMs) to tools and systems that can perform actions, such as scheduling an appointment in a calendar or making a phone call. Put an AI model and a harness together, and you get an AI agent. DeepSeek's aptly named Harness is an open-source harness based around the idea that "everything is a plugin." A plugin is a piece of software that's added on to an existing program to give it new functionality, without altering the original.
