Head-to-head comparison
Nex-N2.5-Mini (Nex AGI) and MiMo-V2.6-Pro (Xiaomi) compared on the ModelCap Index, API price, context window, provider availability, weight access and every public benchmark board they share. Figures are the same ones shown on the live rankings; nothing here is a hidden score.
Snapshot as of 22 September 2026
As of 22 September 2026, MiMo-V2.6-Pro holds the stronger ModelCap Index position (#5 vs #30); Nex-N2.5-Mini is cheaper per output token (Free/1M vs $0.87/1M); MiMo-V2.6-Pro offers the longer context window (1M vs 262K tokens); and Nex-N2.5-Mini ships open weights.
Evidence: global-corpus-prior over 201 held-out anchors (13%); launch card against 6 resolved peers on 3 rows (87%); no cross-lab optimism probe available; shrunk 2.4 toward the measured corpus · 1 public benchmark observation across 1 board. Prices are the lowest listed API offer per million tokens observed on the OpenRouter catalogue.
Scores are the sources' own published figures for each model's best evaluated configuration; ModelCap never re-runs a benchmark.

MiMo-V2.6-Pro ranks higher on the ModelCap Index as of 22 September 2026: #5 against #30. 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.
Nex-N2.5-Mini is cheaper on output tokens: Free/1M against $0.87/1M. Input tokens are Free/1M for Nex-N2.5-Mini and $0.435/1M for MiMo-V2.6-Pro. 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 for Nex-N2.5-Mini versus $1.30 for MiMo-V2.6-Pro. Nex-N2.5-Mini costs 100.0% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
MiMo-V2.6-Pro has the larger context window: 1M tokens against 262K.
The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.
Nex-N2.5-Mini: Open weights. MiMo-V2.6-Pro: 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 1 API provider for Nex-N2.5-Mini and 1 for MiMo-V2.6-Pro, from the OpenRouter catalogue snapshot the site serves; each model page lists the providers and their prices.
Every figure comes from the sealed ModelCap dataset published 22 September 2026; the page re-renders within a minute of each data refresh, and the ModelCap Index positions are the same ones shown on the live rankings.
