The 1-billion-parameter small model "MiniCPM5-1B" is released as an open model, along with the local-run AI pet "MiniCPM Desk Pet"

OpenBMB released MiniCPM5-1B, a 1-billion-parameter open model aimed at strong small-model performance.

The model comes in multiple variants and is designed to run well on local hardware, including CPUs.

OpenBMB also launched MiniCPM Desk Pet, a desktop companion app that uses the model to create a conversational character.

The release underscores growing competition in compact open AI models that can be used on consumer devices.
