How this position was produced · fused launch placement

No general-family board lists this model yet. Its point estimate is the precision-weighted mean of every channel that spoke for it; each channel’s share is the weight it carried. Independent measurements replace this placement as boards list the model.

These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.

The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

MiniCPM5 2B: common questions

How does MiniCPM5 2B rank among AI models?

MiniCPM5 2B holds ModelCap Index position #142 of 350 ranked language models as of 24 October 2026, with an Index score of 43.1 (interval 24.5–61.7); evidence: modeled · peer benchmarks. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.

How much does MiniCPM5 2B cost per 1M tokens?

No live API price is listed for MiniCPM5 2B in the current snapshot as of 24 October 2026 because the latest endpoint refresh was unavailable. ModelCap shows a price only when a provider currently lists one.

Is MiniCPM5 2B open-weight?

Open weights (apache-2.0). Downloadable weights are published under an OSI or free-culture license in the current repository metadata. This describes weight availability, not whether the full training stack qualifies as Open Source AI. The repository is openbmb/MiniCPM5-2B on Hugging Face.

Which benchmarks has MiniCPM5 2B been evaluated on?

MiniCPM5 2B has published results on 3 public boards tracked by ModelCap as of 24 October 2026: AA Intelligence Index 12.5 (#111 of 132), AA Terminal-Bench 2.1 8.6% (#102 of 124) and AA Humanity's Last Exam 8.9% (#165 of 265). Each board page ranks every tracked model on that benchmark. The ModelCap Index scores the results its methodology admits, with published uncertainty, and shows reference boards without scoring them.

When was MiniCPM5 2B released?

MiniCPM5 2B first appeared in the catalogue on 6 Sept 2026. It is the current version in its family. Rank and price movements since then are recorded on the site's changes feed.
