GLM-5.2 Q4_K_M GGUF

First community GGUF quantization of Z.ai's GLM-5.2 (745B MoE, 40B active, 1M context).

Model Details

  • Base model: zai-org/GLM-5.2
  • Architecture: glm-dsa (MoE, 256 experts, 79 blocks, Multi-latent Attention, IndexShare)
  • Quantization: Q4_K_M via llama.cpp (patched for GLM-5.2 MoE layer validation)
  • Format: Split GGUF (8 shards)
  • Total size: ~425GB
  • License: MIT (same as base model)

Quantization Notes

GLM-5.2 hybrid architecture (3 leading dense blocks + 76 MoE blocks + MTP layers) required a one-line patch to llama.cpp quantizer. Patch: use n_layer_all for the MoE expert tensor bounds check in llama-quant.cpp.
