Prerelease: no

Release notes: We are releasing MiniCPM5-1B, the first model in the MiniCPM5 series. It is a dense 1B Transformer built for on-device, local deployment, and resource-constrained scenarios, reaching 1B-class open-source SOTA.

🏆 1B-class open-source SOTA: MiniCPM5-1B reaches an average score of 42.57 across reasoning, knowledge, code, instruction-following, math, logic and agentic benchmarks, above the highest average score of 35.61 among strong open-source models in the same size class; its strengths are most visible in agentic tool use, code, and competition math.

🧠 Hybrid Reasoning: built-in ` chat template, switch via enable_thinking`. The same checkpoint serves as both a fast assistant and a deliberate reasoner.

🛠️ Deployment / Fine-tuning Agent Skills: the repo provides single-page cookbooks for major inference backends and fine-tuning frameworks, each paired with an [Agent Skill](./skills/) to help developers reproduce deployment and fine-tuning workflows.
