Decision facts

  • GPT-4o-mini is #139; o4 Mini is #106 on the same current language board.
  • Index scores are 39.7 for GPT-4o-mini and 51.6 for o4 Mini. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
  • Both positions use Measured evidence.
  • Listed output price per 1M tokens is $0.60 for GPT-4o-mini and $4.40 for o4 Mini. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $0.60 for GPT-4o-mini versus $4.40 for o4 Mini. GPT-4o-mini costs 86.4% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
  • Published context is 128,000 tokens for GPT-4o-mini and 200,000 for o4 Mini.
  • ModelCap currently lists 2 providers for GPT-4o-mini and 1 for o4 Mini.

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.
