Mia-AiLab/GLM-5.3-Flash-EXL3-TR3-4bpw

GLM-5.3-Flash TR3 4bpw — mirror (2x DGX Spark recipe)

This is not an original quantization. It is a byte-identical redistribution of brandonmusic/GLM-5.3-Flash-tr3-4bpw at Hugging Face revision `5ab363a8dcf6405955fd5f99671e01a1c9fb124b` so that the 2× DGX Spark recipe MiaAI-Lab/GLM-5.3-Flash-EXL3-2x-DGX-Sparks stays fetchable if the upstream Hub id moves.

Brandon M. Music created the EXL3/TR3 checkpoint (ShapleyMcg). Z.AI created the base model. Mia's AI Lab only re-hosts this snapshot and serves it on GB10.

What this is

Uniform-K4 EXL3/TR3 routed-expert checkpoint of GLM-5.3-Flash (~164 GiB, 120 safetensor shards). Provenance metadata from the upstream snapshot is kept.

This Hub repo is not Brandon’s SM120 B12X / NVFP4-KV / EP2/DCP2 daily driver. Do not use the verdictai/glm53-flash-exl3-k4:… image with a “this is the Spark recipe” assumption. His original model card is saved as `ORIGINAL_MODEL_CARD.md`.
