Decision facts

  • Step3 VL 10B is #57; Xing4.0 29B A4B is #56 on the same current language board.
  • Index scores are 60.9 for Step3 VL 10B and 60.9 for Xing4.0 29B A4B. 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.
