What happened
DeepSeek said Harness reached 1.54 million daily active users on November 4, up from a 7-day average of 429,000 on October 7, with roughly 92 trillion tokens consumed per day.
Why it matters
The user base grew by more than 1 million people in about a month, suggesting the open-source agent app is being adopted far faster than its August debut would imply.
WHO IT HITSPlugin developers building on Harness may gain an official marketplace and token support, while teams comparing it with closed agent tools now have a self-reported usage benchmark to weigh.
Summaries like this, every morning.
DeepSeek's disclosed user curve is unusually steep for a developer-facing product. Its own figures put the 7-day average at 271,000 users on September 30 and 429,000 on October 7, before the count reached 1.54 million daily active users on November 4.
The agent also carries a large third-party footprint: about 35,000 plugins now ride on Harness, and DeepSeek said roughly 60% of active users have created or installed at least one.
The company is preparing an official plugin marketplace and an author-support program, and has already started distributing tokens to plugin developers, which effectively funds the ecosystem before the storefront opens. The disclosure arrives while Anthropic and OpenAI keep Claude Code and ChatGPT's agent surface closed, and the figures are self-reported against DeepSeek's hosted API with no independent audit.
