Tsinghua-affiliated team open-sources MiniCPM-V 4.6, a 1.3B model tunable on one RTX 4090

清华系团队出手！一张 4090 即可「爆改」，1.3B小钢炮震撼开源

ModelBest, Tsinghua University, and OpenBMB open-sourced MiniCPM-V 4.6, a 1.3B multimodal model that supports full fine-tuning on one RTX 4090 and offers 4x/16x visual token compression for accuracy or speed trade-offs.

Why it matters: HKR-H/K/R all pass: the story gives a concrete open-source multimodal release with size, hardware condition, and token-compression details. It lowers local fine-tuning cost, but it is not a frontier-lab flagship release, so 78–84 fits.
