GLM MoE DSA — fp8-block32: a tiny toolchain fixture

A fp8-block32 storage/reader fixture, built from a tiny random reference checkpoint. Use it to inspect packing, reconstruction, scope accounting, and own-head fidelity comparisons—not to choose a production quantizer.

These weights are untrained, not an assistant, and not a language-quality benchmark. Generated text has no useful semantic quality. No upstream trained weights or training data are implied by an architecture name.

Weight lineage

This is a quantization of a shared native checkpoint, not an independent random initialization and not a fine-tune. HF base_model / base_model_relation: quantized metadata names the real source model.

Exact construction source: malaiwah/glm-moe-dsa-tiny-random-bf16@45563636ef723acfb826755493447dc40c7a0c37.

All 8 derivatives in this family were measured against the same complete source checkpoint identity:

800be70604bef0c3adfb429774f44756d60bf23d141e82d24a032ce25ce0451e

That identity binds config and weight bytes; equal architecture names or random seeds are not used as a substitute. Quantized storage cases use round-to-nearest packing and do not claim GPTQ/AWQ/ModelOpt optimization or calibration.

At a glance

Property	Observed value
Artifact role	Child storage fixture; captured role `quant`; classification `lossy`
Serialized top-level weight files	342,696 bytes (0.327 MiB); metadata, tokenizer and evidence excluded
Source-model generated parameters (before packing)	277,824
Fixture vocabulary	260 tokens; independent byte tokenizer, not upstream vocabulary
CPU stack	Python 3.12; Torch 2.11.0+cpu; Transformers 5.16.1; two Torch threads in the recorded capture workflow
Remote model code	Not required: native Transformers class behind QFS

Size is serialized artifact size, not runtime RAM or a capacity/performance guarantee. Packed-array element counts are not model parameter counts.

What is actually included

Four text decoder layers (one dense, three MoE), MLA attention, alternating full/shared DSA indexers, 8 routed experts/top-2 plus one shared expert, and a complete untied vocabulary head. Native FP32 router buffers are retained; no MTP.

Storage intervention: fp8-block32; random FORMAT fixture.

GLM MoE DSA; full random tiny checkpoint; header-derived GGUF geometry; not all GGUF architectures
Output-head policy: native. The comparison replays each side through its own sealed head, including any head error; the reference head is not substituted.
Weights reconstructed to BF16; dynamic FP8 activation quantization not captured; no serving-kernel parity claim

The repository file inventory includes config.json, generation_config.json, tokenizer.json, tokenizer_config.json, scope.json, build.json. Exact build/runtime/license inventories are linked below. A file may describe historical provenance without being an executable entry point.

Good community uses—and boundaries

Learn how to download pinned artifacts, seal a small synthetic token panel, capture hidden states and replay a full vocabulary head.
Debug model-family adapters, strict tensor loading, storage decoders, or reproducibility tooling without downloading a production-sized checkpoint.
Reproduce a narrowly scoped result, report an adapter/reader regression, and retain the source, panel and runtime identities needed to explain it.

Not established: trained-model accuracy; useful instruction following; quantizer optimization quality; original production-weight compatibility; GPU/NPU/serving-kernel parity; cross-hardware determinism; long-context behavior outside the recorded panel; throughput or paid-compute admission.

RTN is round-to-nearest packing, not optimization. These cases do not run GPTQ, AWQ or AutoRound optimization, calibrated ModelOpt/CT/QAT training, or activation-aware tuning. CPU reconstruction does not execute the original packed GEMM or serving activation arithmetic.

Model family, root dataset and evidence

Exact construction source: malaiwah/glm-moe-dsa-tiny-random-bf16@45563636ef723acfb826755493447dc40c7a0c37. This is the actual source pin; later documentation commits do not rewrite that history. Family fidelity-root dataset repository and storage evidence bundle. The root model is separate; this child must not be registered or represented as the base model. Canonical roots and their evidence are published; registry links distinguish native bases from child/control artifacts.

Full comparison receipt includes per-context/tokenwise evidence, comparison gates and disclosures. Receipt self-digest: 409c3c36bee9b60ae381787542c2c96ce8f56a1e8f113a0b9dff7a0c5204650c. No threshold or usable determinism floor is invented here.

Material disclosures from the observed receipt:

HEAD-1d: each side replayed through its own sealed head (reference 2364995d4009, candidate 2364995d4009); head error is inside the measurement, as under HEAD-2, and nothing is substituted. The heads are content-identical.
candidate was captured from a WEIGHTS-ONLY RECONSTRUCTION (fp8-block-dequant-to-bf16, output bfloat16). The stored weights were decoded before the model forward; native quantized GEMM and serving activation arithmetic are not measured. Decoder provenance is in the sealed runtime receipt. The comparison is advisory.
candidate was captured from a bf16 materialisation of its block-scaled FP8 weights (fp8-block-dequant-to-bf16); the checkpoint declares activation_scheme: dynamic, so a served W8A8 deployment also quantizes activations per token at runtime. That term is not in this number, which is expected to understate the served divergence; it is not a mathematical bound. The comparison is advisory.

Runtime requirements and safe local reproduction

Replay the published evidence without loading a model

This uses QFS's existing NumPy FP64 comparator in a Torch-free environment. It reads the stored hidden states and each side's own head. No model forward, remote model code, GPU, upload or registry mutation is involved. Runtime receipts name the actual backend; last-bit differences from another FP64 implementation are not a new quality claim. Synthetic exact controls remain zero.

Set QFS to a reviewed Quant Fidelity Suite checkout and use Bash:

Reconstructed format comparisons are intentionally advisory and normally return exit code 2 while writing a valid receipt. Inspect that receipt; do not silence refusals or interpret an advisory result as a production-quality ranking.

Capture the actual checkpoint

Capture uses a separate pinned Torch CPU environment. The input below is the original token-panel format, not a sealed capture's internal panel/ folder. The native source, tokenizer and model revisions remain explicit. Set AUTHOR to your own HF handle; the dataset repository argument is attribution only and nothing is uploaded by these commands.

Custom code, where required above, is explicitly pinned and executed only after your consent; hash verification is provenance, not a sandbox.

Licensing and detailed provenance

The fixture repository retains its mit license in LICENSE. This covers the fixture only according to that exact text; architecture inspiration is not relicensing of upstream weights, cards, code, or configuration. Dependencies retain their own licenses (native Transformers implementation: Apache-2.0). No upstream trained tensors are claimed to be copied.

The exact source license is retained, unchanged, from malaiwah/glm-moe-dsa-tiny-random-bf16. The storage conversion does not grant new upstream rights.
