- Index scores are 58.8 for R1 0528 and 57.9 for Nemotron 3 Ultra. 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 $2.15 for R1 0528 and $3.13 for Nemotron 3 Ultra. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $2.08 for R1 0528 versus $2.81 for Nemotron 3 Ultra. R1 0528 costs 26.2% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
