GGUF that fits one DGX Spark (108.3 GiB, PPL 3.354), with a block-sensitivity scan
Thank you for releasing GLM-5.3-Flash under MIT. We have published two GGUF quantizations of it built with stock llama.cpp and Unsloth's importance matrix:
- Spark (108.3 GiB, 2.97 bpw): fits one NVIDIA DGX Spark with 16K context and the vision projector loaded.
- Prime (118.0 GiB): uniform IQ3_XXS experts over a Q8_0 core, for machines with about 125 GiB or more.
The Spark tier was not built by a rule of thumb. We spliced 3-bit expert tensors into a 2-bit file one block of seven MoE layers at a time and measured wikitext-2 perplexity for each block. The best block (MoE layers 31–37) gained 0.100, the worst (38–44) gained 0.034 for the same bytes, so the 3-bit gate/up tensors went to layers 24–37 and a 6-bit core paid for them.
Perplexity (wikitext-2, 20 × 2048 / 30 × 512, ± standard error): Spark 3.354 ±0.047 / 2.765 ±0.060; Prime 3.253 ±0.045 / 2.702 ±0.059. The published BF16 figure at 30 × 512 is 2.2474, so Spark is about 23% above it.

Technical note with every number, the commands as run, a limitations section and a negative result (lossless entropy coding of the 118 GiB file was measured and rejected): https://yogiq.ai/research/glm-5-3-flash-on-one-dgx-spark
Only wikitext-2 perplexity was measured; no task benchmarks, no KL divergence. Corrections welcome.
