Notes
MoE model built on GLM-4.5-Air (106B total, 12B active); needs transformers>=4.57.1, sglang>=0.5.3 or vllm>=0.10.2, and the example serve commands use 4-way tensor parallelism. Thinking mode is on by default, and the card says pure-text Q&A is weaker because this release focused on multimodal use.
