What users praise
- • Credentialed workforce of doctors, lawyers, engineers, and writers — not open-call crowd annotators
- • HANDBOOK.md is widely cited as evidence that long-context policy adherence is genuinely hard
- • Late-2026 catalog breadth: GDP.xlsx, sudo L7, DAYJOB, Chartography, ComplexConstraints, Tuesday Work Index
- • Kimi K2.7 post-training run produced concrete gains (+20.0pp SWE-Marathon) as a public proof point
What frustrates them
- • Pricing is 'contact' only — no public tiers, no rates, frustrating for procurement and comparison
- • Benchmarks are self-published; HN commenters question methodology and potential sponsor influence
- • Independent alternatives (GDPVal-AA, Terminal-Bench 4.0, FrontierCode) erode the differentiation case
- • Gig applicant screening is brutal — YouTube reviewers warn this is 'not for everyone'
