DeepSeek just put the first hard number on the agent era, and it's less a user count than a power bill. The Hangzhou lab said Sunday that Harness, its open-source agent app, reached 1.54 million daily active users on November 4 — less than three months after version 0.1 launched on August 13, and up from roughly 271,000 at the end of September. The figures were disclosed on X and first reported by Bloomberg.

Harness added more than a million daily users in about a month — 429,000 by October 7, then 1.54 million by November 4. The token math is what should worry anyone selling compute. Those users chew through roughly 92 trillion tokens a day through DeepSeek's official API — about 60 million per user per day. A chatbot answers and stops; an agent keeps working for hours, calling the model again and again. The gap between those two workloads is now measurable, and it's orders of magnitude.

Every lab racing to ship agents — OpenAI with Dot, Anthropic with Claude Code, Meta with Muse — is betting users will hand over long-running work. DeepSeek is the first to show what that bet costs: a lot more than chat ever did. If agents keep growing like this, the bottleneck stops being who has the smartest model and becomes who can afford to run one that never clocks out.

The ecosystem play is the other half of the announcement. The company says about 35,000 third-party plugins have already been built for Harness, roughly 60% of users having created at least one, and it's planning an official plugin marketplace plus a support program for authors. It's the app-store move, applied to agents: own the distribution, and the model underneath matters less.

Two caveats, and they're not small. The figures are DeepSeek's own disclosures, with no independent verification and no published definition of an active user. And the count covers only people on DeepSeek's official API — anyone self-hosting the open-source code doesn't show up, so the real footprint is almost certainly bigger than 1.54 million.

Still, the direction is unmistakable. A week ago DeepSeek was open-sourcing a coding agent that doesn't wait to be asked. Now 1.5 million people a day let an agent work unsupervised. The race has moved from who can answer best to who can be trusted to keep going — and DeepSeek just showed the meter running.
