ModelBest open-sources MiniCPM5-1B, topping sub-2B models on AA-Index

面壁智能开源 MiniCPM5-1B：在 AA-Index 上超越所有 2B 参数以下模型，能跑在手机、浏览器上

ModelBest open-sourced MiniCPM5-1B, a 1B-parameter edge language model that beats all sub-2B models on AA-Index, uses a 0.5GB weight file after INT4 quantization, and runs on phones and browsers.

Why it matters: HKR-H/K/R all pass: MiniCPM5-1B has concrete params, quantized size, and edge runtime claims. It is still a small-model release, below flagship-model impact.
