zandenAI/GLM-5.2-FP8-Uncensored - an FP8 block-scaled
MoE-DSA (Mixture-of-Experts with DeepSeek-V3-style sparse-attention indexer) model,
141 safetensors shards, architecture GlmMoeDsaForCausalLM (MLA attention +
256 routed experts x 8 active + 1 shared expert + DSA indexer + 1 MTP draft layer).jeweled/GLM-5.2-Uncensored-MLX-Q8 - uniform 8-bit (master, ~736 GB)jeweled/GLM-5.2-Uncensored-MLX-Q6down8 - mixed: base 6-bit, MoE down_proj 8-bit (~736 GB)jeweled/GLM-5.2-Uncensored-MLX-Q4 - uniform 4-bit (~418 GB)glm_moe_dsa indexer-sharing fix from
pcuenca's glm-moe-dsa-indexer-sharing branch
(mlx_lm/models/glm_moe_dsa.py). Without it, mlx_lm convert throws
ValueError: Missing 285 parameters because the DSA sparse-indexer tensors don't map under
released mlx-lm 0.31.3. That fix tracks ml-explore/mlx-lm PR #1410
(not yet merged). Discovered via mlx-community/GLM-5.2-DQ4plus-q8 discussion #1.
