minicpm5-1b#

  • Context Length: 131072

  • Model Name: minicpm5-1b

  • Languages: en, zh

  • Abilities: chat, reasoning, hybrid, tools

  • Description: MiniCPM5-1B is 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. Supports hybrid thinking via enable_thinking and native XML-style tool calling (MCP-compatible).
