Qwen3.8-Flash-Next for DACAN

Weights of Qwen3.8-Flash-Next packed for DACAN — our engine, a fork of Strata rebuilt for two RTX 2080 Ti (22 GB, NVLink) and two AVX-512 Xeon sockets. DACAN runs this one model family only.

Status (03.10.2026): complete, 27 files (260.6 GB). The dense GGUF was checked against the file the DACAN service runs: three greedy answers (1 984, 1 931 and 596 tokens) came out identical character for character.

The model and its architecture

Qwen4ExpForConditionalGeneration, model_type: qwen4_exp, GGUF general.architecture: qwen4exp:

125B parameters with 6B activated per token, plus a 51B n-gram embedding table and a 4B MTP layer
48 layers: 12 × (3 × (Gated DeltaNet → MoE) → 1 × (Qwen Sparse Attention → MoE)), hidden size 2560
Gated DeltaNet: 48 V heads, 16 QK heads; Qwen Sparse Attention: 24 Q heads, 2 KV heads
MoE: 512 experts, 10 routed + 1 shared per token, expert width 640
Gated residual (widened residual streams), n-gram embedding at layer 2, 1 MTP layer
Context 262,144 tokens natively

DACAN checks this geometry on load (48 layers, 2560, 512 experts, 10 active, 24 / 2 heads) and refuses anything else, so fine-tunes of Qwen3.8-Flash-Next with the same shape work, other models and pruned variants (REAP etc.) do not.

Two layouts: NVFP4 + Q8 (DACAN) and Q8_0

NVFP4 + Q8 (DACAN) is our name for the layout the DACAN service runs: NVIDIA's NVFP4 routed experts, everything else that is large in Q8_0, the small sensitive matrices left in BF16. The experts are about 95 % of the weights and are read from RAM on every token, so their size sets the speed; the parts every token passes through stay at 8 bits.

part	NVFP4 + Q8 (DACAN)	size
routed experts — gate, up, down × 512 × 48 layers	NVFP4 from NVIDIA's checkpoint: E2M1 values, an E4M3 scale per 16 values, an FP32 scale per tensor	68 GB
attention and DeltaNet projections, shared expert, token embeddings, output head	Q8_0	4.1 GiB
n-gram embedding table	Q8_0 from FP8	54 GB
routers, hyper-connections, sparse-attention indexer, DeltaNet `ssm_alpha/beta`, `ple_key/value`	BF16	1.4 GiB
`ple_conv1d` / norms	F16 / F32	0.01 GiB

The Q8_0 layout swaps the experts for ours in Q8_0 (128 GB) and keeps the rest; it needs 120 GiB of RAM for the experts instead of 63 GiB and answers slower (on Swift 1.5: 49 tok/s against 58, median of 9 runs). The same NVFP4 + Q8 (DACAN) mix of the fine-tune Swift 1.5, with experts we quantized from its BF16 weights, is in tirex2001/Swift-1.5-Qwen3.8-Flash-Next-DACAN.

Files

file	what	size
`Qwen3.8-Flash-Next-Q8_0-experts.bin`	routed experts in Q8_0, requantized by us from Qwen's FP8 checkpoint (`tools/q8_experts.py`: 0.55–0.59 % from the FP8 weights)	128 GB
`Qwen3.8-Flash-Next-NVFP4-experts.bin`	routed experts from NVIDIA's NVFP4 checkpoint, repacked for DACAN (`tools/nvfp4_experts.py`; unpacks to NVIDIA's values exactly, checked on layers 0, 21, 47)	68 GB
`Qwen3.8-Flash-Next-dense-Q8_0.gguf`	everything but the routed experts: attention, DeltaNet, shared expert, router, head — Q8_0 (BF16/F32 where the model keeps them); cut from our 4-bit quant's first shard by `dense_gguf.py`, 1 079 of 1 223 tensors, sha256 `3cceeeca…d470d525`	5.99 GB
`Qwen3.8-Flash-Next-PLE-FP8-Q8_0.gguf`	the n-gram embedding table, Q8_0 from FP8	54 GB
`pack-nvfp4/`, `pack-q8_0/`	DACAN packs (expert index, dense blob, tokenizer): `pack-nvfp4` for NVFP4 + Q8 (DACAN), `pack-q8_0` for Q8_0	1.5 GB
`mtp/`	the MTP draft layer	0.8 GB
`data/profile_other_2609.bin`, `data/usage_other_2609.bin`	routing tables for the run command	0.3 MB

Layout. Put the dense GGUF and the *-experts.bin you use in one folder: pack-*/native_experts.txt names the experts file without a path and DACAN looks for it next to the --native GGUF. The service config we run (NVFP4 + Q8 (DACAN)) is --pack pack-nvfp4 --native Qwen3.8-Flash-Next-dense-Q8_0.gguf --ple-gguf Qwen3.8-Flash-Next-PLE-FP8-Q8_0.gguf --mtp mtp --expert-profile data/profile_other_2609.bin --second-card 1 --second-card-usage data/usage_other_2609.bin --max-context 262144 --kv int8 --spec 4 (full list in the DACAN README).

How to run: see the DACAN README. Measured 03.10.2026 on 2× RTX 2080 Ti + 2× Xeon 8368 (NVFP4 + Q8 (DACAN), free node, greedy):

	tok/s
answer: code / a list after a fresh 19K-token prompt	76.9 / 80.4
answer with reasoning low	71.9
answer at 98K tokens of context	69.9
answer: English / Russian prose	60.4 / 47.0
prompt read from scratch: 19K / 98K tokens	786 / 715

The answer speed follows the MTP drafts: 85–89 % accepted on code and lists, 57 % on English prose, 32 % on Russian. Context 256K (a needle found up to 195K). Details: README-2x2080Ti.
