# 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](https://huggingface.co/brandonmusic/GLM-5.3-Flash-tr3-4bpw)
at Hugging Face revision
[`5ab363a8dcf6405955fd5f99671e01a1c9fb124b`](https://huggingface.co/brandonmusic/GLM-5.3-Flash-tr3-4bpw/tree/5ab363a8dcf6405955fd5f99671e01a1c9fb124b)
so that the 2× DGX Spark recipe
[MiaAI-Lab/GLM-5.3-Flash-EXL3-2x-DGX-Sparks](https://github.com/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`](ORIGINAL_MODEL_CARD.md).
