Decision facts

  • K2 Horizon 375B A23B is #30; Nex N2.5 Max is #14 on the same current language board.
  • Index scores are 67.3 for K2 Horizon 375B A23B and 77.3 for Nex N2.5 Max. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
  • Both positions use Estimated evidence.

These are separate published fields, not a synthetic winner. ModelCap does not collapse price, access, context, and capability evidence into a hidden recommendation score.

Each comparison page is a permanent, shareable URL with the same live figures as this tool: ModelCap Index position, API pricing, context window, provider count, weight access and every shared benchmark board.
