DeepSeek launched a free coding tool and raised API prices 355% on the same day. It collected 135K GitHub stars. Independent audits found tenfold token overhead and a security sandbox that skips networks.
The stars are real. The production readiness is not. Independent audits found tenfold token overhead and a security sandbox that does not cover networks. The free tool locks you into the newly expensive API.
"DeepSeek Harness hit 135K GitHub stars in 4 days, called 'one of the fastest rises in GitHub's history.' Same day: DeepSeek raised API prices up to 355% on its commercial model." [SOURCE ↗]
THE CLAIM. DeepSeek Harness reached 135K GitHub stars in 4 days, called by tech aggregators 'one of the fastest rises in GitHub history.' It launched August 13 as a free, open-source coding agent.
THE CHECK. stars are real (144,872 via GitHub API). But 'fastest in history' is unverified by GitHub or DeepSeek. The same day, DeepSeek raised V4-Pro output prices 355% at peak. Independent technical audits found 41 of 2,000+ claimed plugins actually work, tenfold token overhead vs alternatives, and a security sandbox that excludes network and process visibility.
THE TWIST. the free tool runs on DeepSeek's API. The API just got 355% more expensive. The repo collected 135K stars as a free front door to a newly expensive back end. DeepSeek's official reason: 'allocate resources more reasonably.' The timing says: acquire users first, charge later.
