Worth knowing before you sign

  • Funding amount is reported only by an aggregator
  • Frontier-lab customer claims are unnamed
  • CWE-bench eval set is private, so results are not independently reproducible
  • Its trust centre lists SOC 2 and ISO/IEC 42001 (per rl-list); confirm the reports directly
