DeepSeek's agent program has more than 1.5 million daily users

DeepSeek Harness, the agent program from Chinese AI company DeepSeek, had about 1.54 million daily active users on November 4, 2026. The figure comes from the Harness team's own update and has not been independently verified.

An AI agent is a program that does more than answer questions: it can start working on tasks itself using various tools. Harness is open source, so its code is open to others. Everything in the program, from models and tools to sessions and the user interface, is assembled from plugins. A plugin is an added module that gives the program new features.

Rapid growth in a month

Harness launched as a public beta on August 13, 2026, and a desktop version followed on September 29. According to PANews, there were roughly 271,000 daily users on September 30 (a seven-day average) and roughly 429,000 on October 7. By November 4, the figure had climbed to 1.54 million, an increase of more than 1 million in a little over a month (467-545 percent depending on the starting point).

PANews reports that the figures cover only users of DeepSeek's official API, meaning the technical access to the company's models. Users who run Harness in other ways are not included.

FourWeekMBA also cites about 5.48 million monthly active users. That figure appears only in that source.

Heavy token usage

According to FourWeekMBA, daily usage was about 92 trillion tokens on November 4. Tokens are the small chunks of text that AI models work in, and they are often used as a measure of how much a service is being used. That works out to about 60 million tokens per active user per day.

Plugin marketplace on the way

There are about 35,000 third-party plugins, and roughly 60 percent of active users have created or installed at least one.

The Harness team has announced that it will build an official plugin marketplace and a support program for plugin developers. The program is to include token incentives, technical exchanges and recommendations of works. This is a plan, and no launch date, revenue sharing or fee structure has been announced for the marketplace.

If the figures hold up, they show that open agent programs can gain traction quickly. But because they come from the team itself, they should be read with caution.
