GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF

A per-layer GGUF library of Unsloth's unsloth/GLM-5.3-Flash-GGUF (UD-IQ4_XS). These are the same quantized weights, sliced once into one file per transformer block plus the shared parts, so any contiguous layer window [A, B) can be assembled at load time. It's built for dreamcatcher, xAutonomics' fork of ik_llama.cpp, which serves a library either in a single process or split across hosts.


base model	`zai-org/GLM-5.3-Flash`
source quant	`unsloth/GLM-5.3-Flash-GGUF` · `UD-IQ4_XS` · pinned revision `621d456e93` · 5 shards
architecture	`glm5next` · 46 blocks
files	48 (embd, layer, nextn, output) · 146.5 GiB
integrity	`manifest.json`: blake2b-128 per whole file and per tensor
sliced with	`layer_distribution.slice` (the slicer commit is in the `SLICER_COMMIT` file); nothing was re-quantized

Support status

Measured on the dreamcatcher tree (status as of `c2f8b680`; the linked document is authoritative):

glm5next — CUDA verified (library head/tail ring coherent, greedy, 7.6 tok/s, experts on CPU; library ≡ monolith 1383/1383 hashes). The mono-vs-library runtime A/B is done — hidden states md5-identical mono vs library (the STAGE_EMIT=hidden logits abort that blocked it is fixed, meta#93). Vulkan: not measured for this architecture on the published tree (the RDNA3.5 APU proof was the expert-server path with GLM-5.3-Flash experts, not a local Vulkan run).

Only model files from huggingface.co/xautonomics are supported by dreamcatcher. Other GGUFs, including libraries you slice yourself, may load but are unsupported. Do not rename the files: the loader expects blk-NNNNN.gguf / parts-*.gguf / manifest.json exactly.

Layout

blk-00000.gguf … blk-00044.gguf   one transformer block each
parts-embd.gguf                          token embedding (every stage loads it)
parts-output.gguf                        output norm + head (every stage loads it)
parts-nextn-NNNNN.gguf                   NextN/MTP block(s)
manifest.json                            file list, sizes, per-file + per-tensor hashes, source provenance

A stage that serves layers [A, B) needs blk-A … blk-(B-1) plus the parts-* files and manifest.json.

Use

Single process (the whole model on one host):

llama-server --model-dir /models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF

Multi-host ring (stages exchange hidden states over TCP; each host needs low-latency, direct node-to-node links — see the dreamcatcher README):

llama-stage-runner --role tail --listen 8081 --model-dir /models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF --layers 24,46
llama-stage-runner --role head --connect <tail-host>:8081 --model-dir /models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF --layers 0,24

Plan a split for your hosts (weights-only screen; the proof is a survived prefill), and verify the download before launching:

python3 -m layer_distribution.plan /models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF/manifest.json --node a:16GiB:200GiB:8080 --node b:24GiB:200GiB:8081
python3 -c "from layer_distribution import verify; r = verify('/models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF', '/models/GLM-5.3-Flash-UD-IQ4_XS.LAYR.GGUF/manifest.json'); print(r.passed, r.hash_verified)"
