MiMo-V2.5 ranks higher on the ModelCap Index as of 23 September 2026: #43 against #45. 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 is cheaper on output tokens: $0.28/1M against $4.00/1M. Input tokens are $0.14/1M for MiMo-V2.5 and $1.20/1M for GLM 5V Turbo. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $0.42 for MiMo-V2.5 versus $4.40 for GLM 5V Turbo. MiMo-V2.5 costs 90.5% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
MiMo-V2.5 has the larger context window: 1M tokens against 203K.
Arena coding: MiMo-V2.5 1491, GLM 5V Turbo 1489 — MiMo-V2.5 leads.
MiMo-V2.5: Open weights. GLM 5V Turbo: API only. Open weights mean the checkpoint can be downloaded and self-hosted under its licence; API-only models are available solely through hosted endpoints.
ModelCap currently lists 6 API providers for MiMo-V2.5 and 1 for GLM 5V Turbo, from the OpenRouter catalogue snapshot the site serves; each model page lists the providers and their prices.
