Summary

The creator shares the open-source release of MiniCPM-V 4.6 (1.3B parameters), the smallest model in the MiniCPM-V family. It is built for edge devices such as phones and laptops. The announcement says it beats Qwen3.5-0.8B on OCR, grounding, and hallucination benchmarks.

Key points

• MiniCPM-V 4.6 has 1.3B parameters and is open source.
• It is the smallest model in the MiniCPM-V family.
• It is said to beat Qwen3.5-0.8B on OCRBench, RefCOCO, HallusionBench and MUIRBench.
• It is built for edge use: low hardware requirements and good compatibility with mobile devices and laptops.
• Its optimized ViT (vision encoder) gives about a 50% reduction; the quoted text is cut off before saying what is reduced.
