Decision facts

LongCat 2.0 is #16; GPT-6 Sol is #2 on the same current language board.
Index scores are 81.7 for LongCat 2.0 and 89.3 for GPT-6 Sol. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
Evidence differs: LongCat 2.0 is Estimated; GPT-6 Sol is Measured.
Listed output price per 1M tokens is $1.20 for LongCat 2.0 and $10.00 for GPT-6 Sol. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $1.20 for LongCat 2.0 versus $9.00 for GPT-6 Sol. LongCat 2.0 costs 86.7% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
