- Qwen/Qwen3.8-Flash-Next
---

This tiny model is intended for debugging. It is randomly initialized using the configuration adapted from [Qwen/Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next).

Structural comparison with `Qwen/Qwen3.8-Flash-Next`:

| Feature | Source | Tiny |
|---|---|---|
| Architecture / modalities | Qwen4Exp; text, image, video | Same |
| Vocabulary / tied embeddings | 248,320 / false | Same |
| Backbone layers / hidden size | 48 / 2,560 | 8 / 8 |
| Attention Q/KV heads; head dim | 24/2; 256 | 12/1; 32 |
| Attention cycle | 3 linear + 1 QSA | Same; two cycles |
| Linear key/value heads; head dim | 16/48; 128 | 4/12; 32 |
| Routed experts / top-k | 512 / 10 | 32 / 10 |
| Expert/shared intermediate size | 640 / 640 | 128 / 128 |
| Hyper-Connections / mixing rank | 4 / 320 | 4 / 4 |
| QSA heads / dimension / token budget / compression | 4 / 128 / 2,048 / 4 | Same |
| PLE layer / n-gram orders / heads per order | 2 / 2,3 / 8 | Same |
| PLE rows / embedding columns / dtype | 320,001,536 / 160 / BF16 | 9,216 / 1 / BF16 |
| PLE hash bucket base | 20,000,000 | 512; official prime layout |
| PLE convolution / serialized table shards | 4 / 128 | Same |
| MTP | 1 QSA layer; HC fusion; shared token embeddings | Same |
| Vision depth / hidden size / output size | 27 / 1,152 / 2,560 | 2 / 64 / 8 |
| Vision patch / temporal patch / merge | 16 / 2 / 2 | Same |

PLE retains the source n-gram orders, head count, hash/prime-layout algorithm,
projections and convolution with reduced auxiliary hash capacity. The main token
vocabulary and IDs are unchanged.
The Qwen4Exp Hyper-Connections/MTP TP=4 path requires an eight-wide hidden state:
the four-wide configuration creates non-contiguous per-rank MTP block outputs in
vLLM. The two untied BF16 token embedding/head matrices at width 8 occupy
7,946,240 bytes; the complete verified checkpoint is 10,886,632 bytes.
Tokenizer and processor assets are copied unchanged from the pinned source.
vLLM 0.32.0 was verified on one four-NVIDIA-H20 node with TP=4, CUDA Graph,
three-token MTP, and real text, image, and four-frame video requests.

### Example usage:

- vLLM (✅ verified)

```bash
export VLLM_ALLREDUCE_USE_FLASHINFER=0
export VLLM_ALLREDUCE_USE_SYMM_MEM=0
vllm serve tiny-random/qwen3.8-flash-next \\
  --tensor-parallel-size 4 \\
  --disable-custom-all-reduce \\
  --kernel-config '{"moe_backend":"triton"}' \\
  --gdn-prefill-backend triton \\
  --speculative-config '{"method":"mtp","num_speculative_tokens":3}' \\
  --max-model-len 4096 \\
  --max-num-batched-tokens 512 \\
  --max-num-seqs 4 \\
  --gpu-memory-utilization 0.3 \\
  --compilation-config '{"cudagraph_capture_sizes":[1,2,4,8,16]}'
```

- SGLang (unverified)

  - Run on one four-GPU node. Enables TP=4, NEXTN/MTP and CUDA Graph.
  - Unverified on the tested NVIDIA H20 worker: its CUDA 12.2 driver cannot
    load the CUDA 13 SGLang kernel and TileLang artifacts required by this
    Qwen4Exp release. Use the Test environment versions with a CUDA 13-capable
    driver for TP=4 validation.
