tooling and Qwen3.6 GPTQ-Pro recipe this run was aligned with.
Artifact Summary
Table with columns: Field, Value| Field | Value |
|---|
| Source model | Jackrong/Qwopus3.6-35B-A3B-v1 |
| Architecture | Qwen3_5MoeForConditionalGeneration |
| Model type | qwen3_5_moe |
| Tensor files | 6 |
| Safetensors size | 20.81 GiB |
| Indexed tensors | 124595 |
Quantized qweight tensors |
The artifact contains source MTP and vision/visual tensors in its weight index.
That does not mean MTP speculative decoding or multimodal serving is already
recommended. The validated use so far is text-oriented GPTQ serving and
Terminal-Bench agent evaluation.
Quantization Recipe
Table with columns: Setting, Value| Setting | Value |
|---|
| Method | GPTQ-Pro / GPTQModel |
| Bits | 4 |
| Group size | 128 |
| Symmetric quantization | true |
| Desc act | false |
| True sequential | true |
| Calibration dataset |
Dynamic skip rules preserved these module families instead of quantizing them:
embed_tokens
lm_head
mtp
norm
vision
visual
In practical terms, the language tower linear layers are the intended GPTQ-Pro
payload, while embeddings, norms, MTP, and vision-related tensors remain
preserved as non-quantized tensors.
Intended Serving Shape
This checkpoint is intended for advanced users testing text-only vLLM or
GPTQ-compatible serving for Qwen/Qwopus MoE checkpoints.
A starting vLLM shape for text-only testing:
vllm serve XReyRobert/Qwopus3.6-35B-A3B-v1-GPTQ-Pro \
--served-model-name qwopus3.6-35b-a3b-v1-gptq-pro \
--language-model-only \
--dtype float16 \
--quantization gptq_marlin \
--tensor-parallel-size 1 \
--max-model-len 262144 \
--max-num-seqs 1 \
--kv-cache-dtype fp8_e5m2 \
--reasoning-parser qwen3 \
--enable-auto-tool-choice \
--tool-call-parser qwen3_coder \
--enable-prefix-caching \
--gpu-memory-utilization 0.95 \

Serving context for the published Smoke24/vLLM measurements:
The Smoke24/vLLM numbers were collected on an internal llm-residency vLLM
deployment. The custom image recipe is not published yet, so this card does not
present that image as a public reproduction target. The stable serving knobs
captured from the run are listed for context.
Table with columns: Field, Value| Field | Value |
|---|
| Nomad job profile | vllm-qwopus36-35b-a3b-262k |
| Served model name | qwopus3.6-35b-a3b-v1-gptq-pro-foem-4bit-g128-ns256-ctx262k |
| Critical flags | --dtype float16, --quantization gptq_marlin, --kv-cache-dtype fp8_e5m2, --reasoning-parser qwen3, --tool-call-parser qwen3_coder, --max-model-len 262144, --max-num-batched-tokens 2096 |
| Benchmark context |
Treat the command as a serving starting point, not a compatibility guarantee
for every vLLM release. GPTQ-Marlin, Qwen3.6 MoE handling, and multimodal
processor behavior are all loader-version sensitive.
The RTX 3090 image above reflects separate 262k-context serving validation.
Public vLLM Reproducibility
This artifact has a public reproducibility path on the unmodified upstream vLLM OpenAI image:
- image:
docker.io/vllm/vllm-openai:nightly-7a1eb8ac2ec4ea69338c51dc7afd4b15010abfa8
- vLLM version observed in validation:
0.20.1rc1.dev16+g7a1eb8ac2
- GPU class: single RTX 3090 24 GB / Ampere
--enforce-eager was not used
- no local sleep/wake patch or
localhost/*sleepwake* image is required for the validation below
Validated serving shapes:
--max-model-len 131072 validated with --gpu-memory-utilization 0.95
--max-model-len 262144 validated with --gpu-memory-utilization 0.96
--language-model-only, --dtype float16, --quantization gptq_marlin
--kv-cache-dtype fp8_e5m2, --enable-prefix-caching, --max-num-seqs 1
--max-num-batched-tokens 2096, --max-cudagraph-capture-size 32
- ,
The 262k profile is tight on 24 GB GPUs; gpu_memory_utilization=0.95 was short on KV cache in validation, while 0.96 passed.
Validation And Benchmarks
Completed artifact checks:
- Local shard index inspection completed before upload.
- Remote file list verified after upload.
- Remote
model.safetensors.index.json verified after upload.
- Index metadata total size matches the local safetensor shards.
- The remote artifact contains the expected six safetensor shards.
Terminal-Bench 2.0 Smoke24 result and associated vLLM serving measurements.
This Smoke24 run used max_model_len=131072 for apples-to-apples comparison
with the other local models in this publication batch:
Table with columns: Run, Score, Success rate, Wall-time, Output tokens, Observed decode, LLM API time| Run | Score | Success rate | Wall-time | Output tokens | Observed decode | LLM API time |
|---|
qwopus3.6-35b-a3b-v1-gptq-pro-foem-4bit-g128-ns256 | 12/24 | 50.0% | 226.7m | 622.8k | 138.6 tok/s |
Smoke24 is a fixed 24-task Terminal-Bench 2.0 comparison corpus, not a full
Terminal-Bench leaderboard run. The score above is useful for fast regression
and local serving comparison, not for broad model ranking.
Task list and harness shape:
MTP And Vision Status
config.json advertises MTP support, and the index contains mtp.* tensors.
- MTP tensors were preserved, not the primary quantization target for this release.
- MTP speculative decoding has not yet been validated as a recommended path for
this artifact.
- Vision/visual tensors are present, but multimodal serving has not yet been
validated for this quantized artifact.
For now, publish and use this as a text-first GPTQ-Pro MoE artifact.
Limitations
- Experimental quantization.
- Terminal-Bench Smoke24 is a small local comparison corpus, not a full
benchmark submission.
- MTP speculative decoding is not yet a supported recommendation for this
artifact.
- Vision tensors are preserved, but vision behavior has not been validated.
- Loader behavior may vary across vLLM, Transformers, GPTQModel, and
GPTQ-Marlin versions.
