Provenance
The fast variant keeps the GatedDeltaNet recurrence-control projections in BF16 and
uses the companion's optimized INT4 MTP/lm-head tensors plus INT8 token embeddings.
The vision tower remains higher precision. This repository contains all model shards,
configuration, tokenizer, MTP extra tensors, and mtp_draft_vocab_ids.pt required by
from_pretrained(); it is not an official Qwen release.
vLLM
This checkpoint is intended for vLLM with the DFlash2 backport and the Qwen3.8
compressed-tensors support. The Club3090 DFLASH15 profile uses:
- TP=2, RTX 3090-class Ampere;
- W4A16 weights, BF16 KV, FlashAttention;
SPEC_N=15, lookup-augmented DFlash2, and single-stream serving;
GPU_MEMORY_UTILIZATION=0.85 on WSL2/PCIe rigs.
The DFlash2 drafter is a separate checkpoint and is not embedded in this repository.
Local evidence
On one 2x RTX 3090 WSL2 rig, the target plus DFLASH15 measured approximately 105.94
narrative and 188.06 code decode tokens/s, with a validated 244,320-token ceiling.
These are rig-specific measurements, not a universal performance claim. The exact
launcher, patch pins, benchmark logs, and caveats are maintained in the Club3090 PR.
