DeepSeek says its Harness agent software had 1.54 million daily active users on November 4, counting only people accessing its official API. The team disclosed the figures on November 5, according to reports from IT Home and The Paper, alongside plans for an official plugin marketplace.
The count covers a particular way of using Harness, rather than DeepSeek’s entire chatbot audience or everyone running the open-source software. Sulat has not independently verified the usage totals. The published reports do not explain the activity threshold or how users are deduplicated.
The chart mixes weekly averages and one day
DeepSeek’s growth graphic, reproduced by Dahe Cailifang, needs a careful reading. The earlier points are daily averages over seven consecutive days beginning on the labelled date. The November 4 figure is a single-day count.
On that comparable weekly basis, average daily users rose from 271,000 during September 30–October 6 to 1.40 million during October 28–November 3. The separate November 4 result should not be treated as another seven-day average.

DeepSeek also reported roughly 92 trillion tokens consumed daily, according to IT Home. That usage figure does not by itself establish revenue or the number of paying customers.
A marketplace for plugins
Harness provides the software around an AI model that lets it work with tools and carry out tasks. DeepSeek’s official product page describes a desktop application and a web interface for work including documents, spreadsheets, coding and background jobs. Its architecture assembles capabilities through replaceable plugins.
The company says about 35,000 third-party plugins have appeared since launch, and around 60% of active users have created or installed at least one. IT Home reports that DeepSeek plans to improve plugin API stability and compatibility, strengthen security mechanisms and build an official marketplace to help developers distribute plugins and users find them.
A support programme for plugin authors is also being prepared, with token incentives, technical exchanges and recommendations of their work. The November 5 report gives no launch date for the marketplace or the support programme.
The current GitHub repository still labels Harness a developer preview and warns of compatibility-breaking changes. Its MIT-licensed code is available publicly, but developers building plugins should expect the underlying interfaces to keep changing.
