Decision facts
- GPT-5.4 Mini is #45; GPT-5.4 Nano is #112 on the same current language board.
- Index scores are 69.9 for GPT-5.4 Mini and 52.9 for GPT-5.4 Nano. Their published uncertainty intervals do not overlap, but the aggregate Index does not predict performance on every task; compare the relevant benchmark configurations before choosing.
- Both positions use Measured evidence.
- Listed output price per 1M tokens is $4.50 for GPT-5.4 Mini and $1.25 for GPT-5.4 Nano. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $3.75 for GPT-5.4 Mini versus $1.02 for GPT-5.4 Nano. GPT-5.4 Nano costs 72.7% 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 400,000 tokens for GPT-5.4 Mini and 400,000 for GPT-5.4 Nano.
These are separate published fields, not a synthetic winner. ModelCap does not collapse price, access, context, and capability evidence into a hidden recommendation score.
