DeepSeek Harness had 1.54 million daily active users on 4 November, its team said in a 5 November update, Pandaily reported. Harness is DeepSeek’s open-source runtime for AI agents, built around interchangeable plugins. The team also plans an official marketplace where developers could publish those plugins and users could find them. Its user count covers access through DeepSeek’s official API.
Key points
- DeepSeek’s team reported 1.54 million daily active Harness users on 4 November, counted through its official API.
- The team put daily consumption at about 92 trillion tokens and the number of third-party plugins at about 35,000.
- DeepSeek plans a plugin marketplace and an author support programme, but gave neither a launch date.
DeepSeek’s official API user count
Harness v0.1 launched on 13 August, followed by a desktop version on 29 September. Daily active users stood at about 271,000 on 30 September, Pandaily reported. DeepSeek’s team puts consumption across the users it counted at about 92 trillion tokens a day. Tokens are the pieces of text a model processes, so the consumption figure measures activity passing through the service rather than how many tasks were completed.
A separate account puts the monthly audience at 5.48 million, FourWeekMBA reported. It says the team’s figures have not been independently verified and that the official-API count excludes people running Harness with other models. FourWeekMBA also describes the earlier 271,000 figure as a seven-day average, while 1.54 million is the value for 4 November alone. Those are different measurement periods, even though both figures describe daily users.
FourWeekMBA reports a series of seven-day averages beginning at 271,000 from 30 September, rising to 429,000 from 7 October, 665,000 from 14 October, 1.13 million from 21 October and 1.40 million from 28 October. The series marks DeepSeek’s V4.1-Flash-1017 model release on 17 October. AI Affairs previously reported the V4.1-Flash update and paid Search and Fetch APIs. FourWeekMBA says the Harness update does not identify what drove the October rise.
Harness’s 35,000 third-party plugins
DeepSeek’s team says third parties have made about 35,000 plugins for Harness since it launched, with around 60% of active users having created or installed one or more. In Harness, a plugin can supply a model, a tool, storage or part of the interface. Instead of fixing those parts together in one configuration, the runtime lets them be exchanged and combined — much as fittings can change what a workbench is set up to do while the bench stays in place. The team’s plugin figure counts available additions, not how many work reliably together.
Writing a report could involve bringing a model and a specialist tool into the same working setup, rather than using only the capabilities supplied at the outset. The plugin design would make that combination possible, though the team’s figures count installation or creation rather than the quality of the finished work.
Developers have made plugins for content creation, design, context management and scientific research, 36Kr reported. Its account also describes an individual developer’s experience of removing plugins after a setup with more than 15 encountered loops, context overflow and higher token consumption. Each installed tool can bring instructions that the model must read before deciding what to do. That account describes one developer’s experience, rather than a measured failure rate across Harness.
Other plugins described by 36Kr connect coding agents through one interface or give Harness longer-term memory organised by project. AI Affairs has also reported on the Harness team’s coding-agent prototype for GitHub. For developers building on Harness, the replaceable parts offer ways to specialise an agent, while the reported problems with crowded setups make plugin management part of the work.
DeepSeek’s planned plugin marketplace
DeepSeek’s team says it will make the plugin API more dependable and better able to work across different plugins, add protective measures and create an official marketplace for authors to publish plugins and users to discover them. Pandaily reported that the team gave no launch date for the marketplace or its planned author support programme. The programme is intended to offer token incentives, technical exchanges and featured placement, with details to be shaped by community feedback.
The team has also invited startups and companies to make their products and specialist capabilities available as Harness plugins. An official marketplace would put distribution alongside the runtime itself, where developers already have the option to replace built-in functions with third-party components. For companies considering a plugin, the proposed security and compatibility work concerns the route by which that component would reach users, as well as whether it would keep working as Harness changes.
Harness has already added plugin management features, according to 36Kr, including compatibility checks, installation diagnostics and controls for stopping or removing plugins. Its account says the 4 November release candidate for version 0.2.2 also adjusted how context is reused between consecutive tool calls and set separate instruction budgets for global and project-level AGENTS.md files.
