MiniCPM5-2B: 2B-parameter open model runs agents offline on 2GB RAM, tops sub-4B open models

MiniCPM5-2B is a fully open-source 2B-parameter model that runs agents entirely offline on any laptop or phone with just 2GB RAM.

The poster tested it with a multi-step task — browse Hugging Face, find the Models section, evaluate models on multiple criteria, export a top-15 CSV — and it succeeded, working well even under the Hermes agent framework. In the Artificial Analysis Intelligence Index v4.1.1 cited in its release, it scores 23, ranking #1 among open models under 4B parameters.

The author cites the "Densing Law" from Tsinghua/ModelBest researchers: open pretrained model capability density roughly doubles every 3.5 months — what matters now is intelligence density, not model size.
