DeepSeek V4 Pro 0813 ranks higher on the ModelCap Index as of 9 September 2026: #25 against #26. 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.
MiMo-V2.5-Pro is cheaper on output tokens: $0.87/1M against $1.74/1M. Input tokens are $0.579/1M for DeepSeek V4 Pro 0813 and $0.435/1M for MiMo-V2.5-Pro. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens.
