Decision facts
- o3 is #49; Laguna S 2.1 is #45 on the same current language board.
- Index scores are 61.3 for o3 and 62.6 for Laguna S 2.1. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
- Evidence differs: o3 is Measured; Laguna S 2.1 is Estimated.
- Listed output price per 1M tokens is $8.00 for o3 and $0.18 for Laguna S 2.1. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $8.00 for o3 versus $0.27 for Laguna S 2.1. Laguna S 2.1 costs 96.6% 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 200,000 tokens for o3 and 1,048,576 for Laguna S 2.1.
- Weight access differs: o3 is none; Laguna S 2.1 is restricted.
These are separate published fields, not a synthetic winner. ModelCap does not collapse price, access, context, and capability evidence into a hidden recommendation score.
