DeepSeek‘s open-source agent platform, Harness, reached 1.54 million daily active users on 4 November, less than three months after its first release, according to figures shared by its development team.
The count covers people using Harness through DeepSeek’s official API, and those users processed about 92 trillion tokens a day. The growth has been rapid: daily users averaged 271,000 at the end of September and reached 429,000 by 7 October before jumping to 1.54 million in early November. The figures are self-reported and have not been independently verified.
Harness, first released as version 0.1 on 13 August with a desktop app following on 29 September, turns a language model into an agent that can use tools, manage tasks and carry work through several steps instead of simply answering in a chat window. Its design is built around plugins: models, tools, skills, sessions and sandboxes can all be assembled from components developers can replace or combine. An October update even added an experimental bridge for extensions written for Claude Code.
Around 35,000 plugins from outside developers have appeared since launch, and about 60% of active users have created or installed at least one, the team said. DeepSeek is now preparing an official plugin marketplace and a support programme for plugin creators, offering token incentives, technical exchanges and featured placement. No launch date has been given for either.
The team also published a design article on 31 October setting out a longer-term ambition it calls a Super-agent: agents that retain context across sessions and advance several complicated tasks at once. The next phase of Harness will focus on stabilising the plugin API, strengthening security and giving authors a central place to publish their work.
