DeepSeek says its Harness agent app reached 1.54 million daily active users as of November 4, less than three months after the first version shipped. The count covers users of DeepSeek's official API and is up from about 271,000 on September 30, a jump of roughly 468%.
That works out to about 1.27 million new daily users in the five weeks between the end of September and early November. DeepSeek released the first version of Harness on August 13 and followed it with a desktop edition on September 29.
Usage is heavy as well as broad. Harness users are consuming about 92 trillion tokens a day, a figure DeepSeek also measured among users of its official API.

A plugin ecosystem has grown alongside the user base. The community has built about 35,000 third-party plugins for Harness, and roughly 60% of active users have built or installed at least one, according to the Harness team. That means a majority of the daily user base has extended the agent beyond its default setup.
DeepSeek is now preparing an official plugin marketplace for Harness. The company also plans a token incentive program aimed at developers and a support plan for plugin authors. No launch date has been announced for any of the three.
Harness is DeepSeek's agent runtime, and the company describes it as an open-source application. The disclosures did not include pricing, license terms, revenue-sharing arrangements for the coming marketplace, or which DeepSeek models the app uses by default.
The numbers were posted through the official Harness account on X rather than in a formal company release. DeepSeek has not said when the marketplace or the developer incentive program will go live.
