VerdictThe pragmatic hiring default — Terra handles almost every screening and drafting task at a fraction of frontier cost.The strongest general model for hiring work — but only worth its price on the judgement-heavy steps, not on parsing.

Watch out for
  • Sol is not a substitute for a human on final decisions
  • Public benchmark coverage for this alias is thin
  • Max effort is roughly 24× the cost of Mini — do not point bulk CV parsing at it
  • A frontier model is not a fairness guarantee: you still need audited rubrics and a human on the shortlist
  • Pricing is unpublished, so total cost of ownership is unmodellable today
