The Hangzhou-based start-up reported significant usage metrics as developers embrace the infrastructure designed to transform large language models into independent operators.

Rapid Growth and Massive Token Consumption

DeepSeek announced on Sunday that Harness reached 1.54 million daily active users. Alongside this user base expansion, application programming interface consumers were processing approximately 92 trillion tokens a day as of November 4, translating to roughly 1.1 billion tokens consumed per second.

Unlike standard models that simply respond to prompts, a "harness" provides the software framework enabling an AI agent to autonomously execute complex tasks on behalf of users. US giants like OpenAI and Anthropic previously leveraged similar advantages to develop industry-leading coding tools such as Codex and Claude Code.

Product Evolution and Ecosystem Expansion

DeepSeek initially introduced Harness on August 13, followed by a dedicated desktop application on September 29. These releases allow developers to run agents capable of executing code and interacting with external software.

The accompanying ecosystem has scaled alongside user numbers. Key milestones include:

  • Growth to about 35,000 third-party plug-ins since the platform's launch.
  • An adoption rate where roughly 60 per cent of active users have built or installed at least one plug-in.
  • Community-driven innovations, ranging from academic paper reading and translating tools to conversation transparency utilities.

Cui Tianyi, a former Jane Street engineer who joined the Harness team in March, outlined the long-term vision for the software in a social media post on Sunday.

“Our goal is for DeepSeek’s Harness to act as an operating system for the agent era,” Cui said, comparing the framework to a smartphone operating system pre-loaded with essential tools while supporting downloadable third-party alternatives.

Commercialization and Future Plans

To further nurture this developer ecosystem, DeepSeek plans to launch a dedicated marketplace where users can discover plug-ins and developers can publish them. The upcoming support initiative will feature token grants, promotional assistance, and technical discussions.

As adoption climbs, the company is intensifying its focus on monetizing its foundation models. DeepSeek established its first product division last month, placing Cui at its helm to guide the commercialization strategy.
