Qwen3.7 Plus ranks higher on the ModelCap Index as of 12 October 2026: #33 against #34. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
Ling 3.1 Flash is cheaper on output tokens: Free/1M against $1.28/1M. Input tokens are Free/1M for Ling 3.1 Flash and $0.32/1M for Qwen3.7 Plus.
