Decision facts
- DeepSeek V3.2 is #51; GPT-5.5 Pro is #49 on the same current language board.
- Index scores are 58.2 for DeepSeek V3.2 and 59.1 for GPT-5.5 Pro. 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 $0.40 for DeepSeek V3.2 and $180.00 for GPT-5.5 Pro. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $0.74 for DeepSeek V3.2 versus $150.00 for GPT-5.5 Pro. DeepSeek V3.2 costs 99.5% 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 163,840 tokens for DeepSeek V3.2 and 1,050,000 for GPT-5.5 Pro.
- Weight access differs: DeepSeek V3.2 is open; GPT-5.5 Pro is none.
- ModelCap currently lists 15 providers for DeepSeek V3.2 and 1 for GPT-5.5 Pro.
These are separate published fields, not a synthetic winner. ModelCap does not collapse price, access, context, and capability evidence into a hidden recommendation score.
