This repository is the reusable checkpoint archive for the Qwen3-8B request-level MoS/DFlash experiments. These are draft-model checkpoints, not standalone causal language models.

Pinned dependencies

Target model: Qwen/Qwen3-8B@b968826d9c46dd6066d109eabc6255188de91218
D0 initializer: z-lab/Qwen3-8B-DFlash-b16@9b41424b7109f9c5413454f481b09a82b85333f4
Target tokenizer, embedding, and LM head are runtime dependencies and are not redistributed here.

Archive layout

U1 contains the 8B Generalist plus the four matched joint/MLP-only MoS arms:

text

dflash_legacy.py
registry/
schema/
experiments/
  generalist/mixed-800k/
  joint-mos/d0-init/
  joint-mos/generalist-init/
  mlp-only-mos/d0-init/
  mlp-only-mos/generalist-init/
provenance/original-code/<sha256>/

Each checkpoint directory contains its config, complete safetensors shard set, and index where required. In U1, auto_map.AutoModel selects the repository root module:

dflash_legacy.DFlashDraftModel for code SHA-256 08625e679c8a2f55a919db108dbec6591fbeb9bd4c012ee387757cd578b2ef8a.

The complete hashes are in registry/checksums.sha256 and the artifact manifest. The exact original checkpoint-local code is retained once under provenance/. Later specialist, attention-only, and integrated-router batches must pass their own manifests and verification gates before they are added.

Loading one checkpoint

Pin a verified release tag or commit:

python

from transformers import AutoModel

model = AutoModel.from_pretrained(
    "ryan-0608/MoS-DFlash-Qwen3-8B-Training-Archive",
    subfolder="<manifest load_subfolder>",
    revision="<verified commit or tag>",
    trust_remote_code=True,
)

The target model must be loaded separately. Do not use these draft weights as a standalone text-generation model.

Resume state

U1 does not place FSDP optimizer state in this loadable model repository. Reviewed resume bundles are planned for a separate hash-addressed storage archive; its final location will be documented only after that archive exists and is verified.

bitwise-exact is used only after an actual parity test with accumulation_steps=1.
stateful-non-bitwise means fp32 masters, AdamW moments, and scheduler can be restored, but the original accumulation geometry prevents a bitwise claim.
Raw source training_state.pt files are not published. Only the reviewed, path-scrubbed derivative is eligible.
PyTorch .pt files are pickle-based. Load only from a pinned, verified release.

Data and evaluation boundary

Training/evaluation prompts, prepared datasets, hidden-state features, activations, and per-sample outputs are not included. Dataset-license review is not complete enough to redistribute those materials. Public result artifacts are limited to reviewed aggregate evidence.
