DeepSeek's agent app hit 1.54M daily users in under three months

DeepSeek said Sunday that Harness, its open-source agent application, reached about 1.54 million daily active users on November 4 — less than three months after launch. The count covers only people using DeepSeek's official API, and DeepSeek disclosed the figures in a post on X that Bloomberg reported the same day.

The growth is steep: daily users stood at roughly 271,000 at the end of September, days after the desktop version shipped, and have since grown more than fivefold. Those users burn through about 92 trillion tokens a day — roughly 60 million per user — an early measure of how much heavier long-running agent work is than chatbot chat.

The team says about 35,000 third-party plugins have already been built for Harness, and it plans an official plugin marketplace and a support program for plugin authors, with no launch date announced. The pitch is the agent layer above the model — where DeepSeek is now challenging Anthropic and OpenAI on open-source turf.
