MiniCPM5-2B-Midtrain

We are releasing **MiniCPM5-2B**, the second model in the **MiniCPM5** series, following MiniCPM5-1B. It is a dense 2B Transformer that scales up the same training recipe, built for on-device, local deployment, and resource-constrained scenarios, reaching 2B-class open-source SOTA. 🏆 **2B-class open-source SOTA**: compared with strong open-source models of similar size, MiniCPM5-2B achieves SOTA performance within this comparison set. It remains competitive with 4B-class models overall, while showing its advantages over models of comparable size in coding, mathematics, long-context understanding, tool use, and agentic tasks. #capability-comparison-radar { --foreground: #171717; display: block; width: 100%; max-width: 620px; margin: 0 auto; background: #fff; font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", sans-serif; } #capability-comparison-radar svg { display: block; width: 100%; height: auto; background: #fff; } #capability-comparison-radar .title { fill: var(--foreground); font-size: 16px; font-weight: 600; letter-spacing: 0; } #capability-comparison-radar .axis-label { fill: #333; font-size: 12px; font-weight: 600; } #capability-comparison-radar .ring { fill: none; stroke: rgba(128,128,128,.18); stroke-width: .8; } #capability-comparison-radar .spoke { stroke: rgba(128,128,128,.25); stroke-width: .8; } #capability-comparison-radar .ring-label { fill: #8a8a8a; font-size: 9px; } #capability-comparison-radar .series { stroke-linejoin: round; } #capability-comparison-radar .series.primary { stroke-width: 2.4; } #capability-comparison-radar .legend-label { fill: #171717; font-size: 12px; font-weight: 600; } #capability-comparison-radar .legend-average { fill: #666; font-size: 11px; } #capability-comparison-radar .legend-swatch { rx: 3; } @media (max-width: 900px) { #capability-comparison-radar { overflow-x: auto; } #capability-comparison-radar svg { min-width: 620px; } }
