MiniCPM5-1B is OpenBMB's dense 1B on-device language model and the first checkpoint in the MiniCPM5 series. Its training spans base training, mid-training, and SFT, RL, and on-policy distillation from specialized RL teachers; the released checkpoint supports switchable Think and No Think modes, a 131,072-token context window, and XML-style tool calling for local assistants and resource-constrained deployments.
