Qwen3.6-35B-A3B ยท AWQ INT8 (W8A16)
8-bit quantization of Qwen/Qwen3.6-35B-A3B, produced for efficient vLLM serving. Quantized by axteam.
Revision 2026-11-01 (rebuilt): The MoE router (
mlp.gate) and the shared-expert gate are now compensated during AWQ smoothing (checked on every layer against the original: the router rescale matches the norm rescale, median per-channel difference below 2%). The first upload of this repo left the router and the shared-expert gate uncompensated, so tokens were routed to different experts than in the original. If you downloaded this repo before 2026-11-01 06:13:53 UTC (revision05a077a), download it again. The benchmark and fidelity figures on this card were measured on the rebuilt files.

Quantization details
- Scheme โ W8A16 โ INT8 symmetric weights, group size 32, BF16 activations, stored as compressed-tensors
pack-quantized. - Kept in BF16 โ the vision tower & projector (
model.visual.*), the multi-token-prediction head (mtp.*), all RMSNorms, token embeddings, the LM head, the MoE router (mlp.gate) and shared-expert gate, the SSM non-linear parts (linear_attn.conv1d/A_log/dt_bias). Left unquantized to preserve quality (about 6% of all parameters in this build). - Tokenizer /
chat_template/generation_configare identical to the original.config.jsonis the original plus aquantization_configblock.
This is post-training quantization (PTQ) โ no retraining. AWQ uses a small calibration set (no gradient) to protect salient weight channels before rounding.
Benchmarks (measured)
Every column was measured with the same harness and settings โ lm-evaluation-harness on vLLM, greedy, completion-style prompts without a chat template (0- or 5-shot, as listed in each row). MMLU here is lm-eval's generative variant (mmlu_generative: the model writes the answer letter and only an exact match on the first line counts), so it is not directly comparable with MMLU scores measured another way (e.g. log-likelihood scoring). Percentages are recovery vs. the BF16 original.
| Benchmark | BF16 (original) | FP8-dynamic | AWQ-8bit (this repo) | NVFP4A16 | NVFP4 | AWQ-4bit |
|---|---|---|---|---|---|---|
| MMLU (5-shot, generative) | 64.44 | 67.45 (104.7%) | 64.02 (99.3%) | 69.31 (107.6%) | 68.39 (106.1%) | 74.12 (115.0%) |
| GSM8K (5-shot, strict) | 30.40 | 21.53 (70.8%) | 28.81 (94.8%) | 24.49 (80.5%) | 46.55 (153.1%) | 71.11 (233.9%) |
| ARC-Challenge (0-shot) | 55.38 | 54.61 (98.6%) | 55.46 (100.2%) | 55.03 (99.4%) | 56.23 (101.5%) | 54.78 (98.9%) |
| Winogrande (5-shot) | 76.32 | 75.37 (98.8%) | 76.24 (99.9%) | 74.43 (97.5%) | 74.27 (97.3%) | 75.85 (99.4%) |
| KMMLU (5-shot, direct) | 65.14 | 64.86 (99.6%) | 65.18 (100.1%) | 64.50 (99.0%) | 64.09 (98.4%) | 64.61 (99.2%) |
| HAE-RAE (0-shot) | 74.89 | 74.89 (100.0%) | 75.07 (100.2%) | 75.34 (100.6%) | 74.06 (98.9%) | 73.69 (98.4%) |
| Average | 61.09 | 59.78 (97.9%) | 60.80 (99.5%) | 60.52 (99.1%) | 63.93 (104.6%) | 69.03 (113.0%) |
| Average without MMLU ยท GSM8K | 67.93 | 67.43 (99.3%) | 67.99 (100.1%) | 67.33 (99.1%) | 67.16 (98.9%) | 67.23 (99.0%) |
Note on MMLU and GSM8K: these tasks are scored on generated text (
mmlu_generative,gsm8kstrict-match), so the score depends on whether the model answers in exactly the format the scorer expects (for MMLU only a bare answer letter on the first line counts). For this model they swing widely between builds of the same model (MMLU 64.0โ74.1; GSM8K 21.5โ71.1), and two quantized builds score well above the BF16 original (MMLU: AWQ-4bit 115.0%; GSM8K: AWQ-4bit 233.9%, NVFP4 153.1%). This most likely reflects how each build formats its answers rather than quantization quality, but per-question outputs were not saved, so it was not checked answer by answer. The second average leaves them out.
Evaluation (measured)
Fidelity to the BF16 original on an internal mixed English/Korean set (100 prompts: the BF16 original's greedy answers, scored under each build with the same prompts and scoring code). This build was measured on the rebuilt files with vLLM 0.32 on 2026-11-01; the BF16 reference column was measured on 2026-10-27.
| Metric | This model | BF16 original |
|---|---|---|
| Perplexity (lower = closer) | 1.2948 | 1.2934 (+0.1%) |
| Top-1 next-token agreement | 97.6% | 98.0% |
These measure fidelity to the base model, not absolute task scores.
Requirements
| Runtime | vLLM โ the architecture is in vLLM โฅ 0.17.0; tested here with vLLM 0.32.0. |
| vLLM install | vLLM 0.32 itself needs Python 3.11โ3.14, torch 2.13 (CUDA 13.0 build, so an NVIDIA driver with CUDA 13 support), transformers โฅ5.16.1,<5.20 and compressed-tensors 0.17.0 (both pinned by vLLM; 0.17.0 reads this checkpoint, which was saved with 0.19.0 โ do not upgrade it separately). |
| GPU | NVIDIA Turing (sm75) or newer โ weight-only INT, no special tensor cores needed. V100 (sm70) is not supported. (Kernel choice per GPU from vLLM 0.32's selection code; only B200 was run here.) |
| Memory | Weights: 40.4 GB. Add KV cache (grows with context length ร concurrent requests) and a few GB for activations / CUDA graphs; use --tensor-parallel-size N when the weights do not fit one GPU. |
| Transformers (without vLLM) | transformers>=5.13.0. |
| trust_remote_code | not needed |
Usage (vLLM)
Start an OpenAI-compatible server:
vllm serve axteam/Qwen3.6-35B-A3B-AWQ-8bit --max-model-len 32768
Query it:
curl http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
"model": "axteam/Qwen3.6-35B-A3B-AWQ-8bit",
"messages": [{"role": "user", "content": "๋ํ๋ฏผ๊ตญ์ ์๋๋ ์ด๋์ธ๊ฐ์?"}],
"temperature": 1.0, "top_p": 0.95, "top_k": 20, "max_tokens": 512
}'
Offline inference in Python:
from vllm import LLM, SamplingParams
llm = LLM(model="axteam/Qwen3.6-35B-A3B-AWQ-8bit", max_model_len=32768)
params = SamplingParams(temperature=1.0, top_p=0.95, top_k=20, max_tokens=1024)
out = llm.chat([{"role": "user", "content": "Explain model quantization in two sentences."}], params)
print(out[0].outputs[0].text)
# image input (URL or data: URI)
messages = [{"role": "user", "content": [
{"type": "image_url", "image_url": {"url": "https://example.com/your-image.png"}},
{"type": "text", "text": "Describe this image."},
]}]
out = llm.chat(messages, params)
print(out[0].outputs[0].text)
Recommended sampling (from the original
generation_config.json):temperature=1.0,top_p=0.95,top_k=20. Thinking mode is on by default in the chat template; to turn it off passchat_template_kwargs={"enable_thinking": False}(Pythonllm.chat(..., chat_template_kwargs=...), or"chat_template_kwargs": {"enable_thinking": false}in the request body). Text-only serving: add--limit-mm-per-prompt '{"image": 0, "video": 0}'to skip loading the vision encoder's memory budget.
Reducing KV-cache memory (optional, serve-time)
The KV cache is kept in BF16 by default. KV-cache precision is a runtime choice, independent of the weight quantization above. This is a hybrid model: only its 10 full-attention layers keep a KV cache, while its 30 linear-attention (Gated DeltaNet) layers keep a fixed-size state per request, which --kv-cache-dtype does not change. FP8 halves the full-attention KV cache, so the saving grows with context length and is small for many short requests:
