Hi everyone!
MiniCPM5-1B is currently the strongest open-source model under 2B for on-device use:
It hits SOTA in the 1B-class on agentic tool use, code generation, and tough reasoning tasks while keeping a very small footprint.
The INT4 weights are only around 0.5GB, which makes the local story much more real.
OpenBMB also shipped a cute Desktop Pet fully powered by this model — completely local, no cloud:
