MiniCPM5-2B

Beijing – September 12, 2026 -- ModelBest, a Chinese AI startup, has released MiniCPM5-2B, a 2-billion-parameter open-source language model that ranks first on the Artificial Analysis Intelligence Index among open-source models under 4 billion parameters. The model, built in collaboration with the OpenBMB open-source community, also scored 20 on the Agentic Index, a metric measuring autonomous task-execution capability, outpacing peers in its size category.

Model runs agentic tasks natively on edge hardware without cloud dependency

MiniCPM5-2B natively supports tool calling, deep search, code generation, and multi-step reasoning despite its compact parameter count. ModelBest positions the release as evidence that increasing 'intelligence density' rather than scaling parameter counts can deliver strong performance within the compute, memory, and power constraints typical of edge devices such as PCs, smartphones, robotics, and IoT hardware.
