Hacker News, Lemmy
What users praise
- • Expert workforce of doctors, lawyers and engineers differentiates it from open-call crowd annotators
- • Benchmark catalog — GDP.xlsx, sudo L7, HANDBOOK.md — gets genuine technical engagement on Hacker News
- • Openly grouped with Mercor, Scale AI and Turing as a serious frontier-lab supplier
- • Runs like the Kimi K2.7 post-training show measurable agentic-coding gains with cited deltas
What frustrates them
- • Almost no first-hand user accounts of the product itself in the scraped data
- • Benchmark sponsorship and independence draw pointed skepticism from HN commenters
- • Pricing is contact-only with zero public reference points for contract size
- • Discussed as a vendor category, not a tool — hard to evaluate without a pilot
