Qwen3.8-27B, drinkme pack

A drinkme pack of Qwen/Qwen3.8-27B at commit 1d4bf0f2ff60. drinkme stores the model's BF16 weights losslessly compressed and decodes them during inference, so the pack is smaller than the checkpoint and serves the same bits.

Source	Qwen/Qwen3.8-27B at 1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0
Pack	v1/sip/1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0/
Pack format	1, compression profile sip (tiers 3, 8)
Bits per packed weight	11.25 (BF16: 16)
Size	39.87 GB, 72% of the 55.56 GB BF16 checkpoint
Packed by	drinkme 1.0.0

The pack is self-contained: besides the compressed Linear weights it carries the tensors the codec leaves uncompressed (embeddings, norms), the config, the tokenizer and the chat template, and it serves with no other download.

Serve it

drinkme serve --model Qwen3.8-27B

On a machine with no local pack of this commit, drinkme serve downloads this pack instead of the BF16 checkpoint, checks it as described below, and serves it; --no-hub-pack downloads the checkpoint and packs it locally instead. drinkme's README covers installation.

Check it yourself

The Hugging Face Hub publishes the SHA-256 of every weight file of Qwen/Qwen3.8-27B at commit 1d4bf0f2ff60. drinkme rebuilds each of those files from the pack, byte for byte (its safetensors header, then every tensor: the compressed ones decoded, the others copied), hashes it without writing it out, and compares the hash with the one the Hub lists. It compares the embedded config and tokenizer files with the Hub's hashes the same way. drinkme serve runs this when it downloads the pack; to run it by hand:

hf download drinkme-packs/Qwen3.8-27B-drinkme --include 'v1/sip/1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0/*' --exclude 'v1/sip/1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0/upstream-verified.json' --local-dir drinkme-pack
drinkme verify --upstream --pack-dir drinkme-pack/v1/sip/1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0

It prints one line per file, MATCH, MISMATCH or NOT COVERED, and exits 0 only when every file matches. It writes its own receipt, upstream-verified.json, into the pack directory.

Changes: the upstream model*.safetensors files are not shipped as such. drinkme re-encoded their tensors losslessly into the files under v1/sip/1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0/ (t*.npz, checkpoint/remainder.safetensors, meta.json), from which drinkme verify --upstream rebuilds the original files byte for byte.
