Qwen3.8-27B-Quark-AWQ-INT4-W4A16

INT4 weight-only (W4A16) quantized version of Qwen/Qwen3.8-27B, produced with the AWQ algorithm using AMD Quark.

Weights: INT4, group size 128
Activations: BF16 (unquantized)
Algorithm: AWQ (activation-aware weight quantization)
Calibration: 128 samples, sequence length 512
Base model: Qwen/Qwen3.8-27B (Apache 2.0)

Benchmark results

Benchmark	Setting	This model (AWQ)	BF16 base	Recovery %
GSM8K, 5-shot (flexible-extract / strict-match)	Thinking: `temperature=1.0, top_p=0.95, top_k=20, min_p=0.0, presence_penalty=0.0, repetition_penalty=1.0`, `max_gen_toks=8192`	91.21% / 90.67%	93.33% / 93.33%	97.7%
GSM8K, 5-shot (flexible-extract / strict-match)	Non-thinking: `temperature=0.7, top_p=0.80, top_k=20, min_p=0.0, presence_penalty=1.5, repetition_penalty=1.0`, `max_gen_toks=8192`	91.51% / 90.37%	90.67% / 89.76%	100.9%
Wikitext perplexity	Greedy	8.8250	8.4364	95.6%
BFCL Overall Acc (single_turn)*	Greedy (harness default)	24.06%	24.38%	98.7%

* BFCL Overall Acc reflects only single_turn categories, not the full Gorilla-leaderboard formula (multi-turn/web-search/memory categories were not run and would count as 0 against the public leaderboard's own Overall Acc). Sub-metrics: Non-Live AST 86.58% (base 88.52%), Live AST 81.57% (base 83.05%), Relevance Detection 75.00% (base 75.00%), Irrelevance Detection 72.47% (base 72.22%).

Recovery % = quantized / BF16-base, using flexible-extract for GSM8K rows and base/quantized (inverted, since lower is better) for perplexity — both measured by us against verified-upstream Qwen/Qwen3.8-27B weights, not vendor-reported numbers. GSM8K uses lm-evaluation-harness; non-thinking mode is approximated by pre-closing an empty <think></think> block in the prompt, since the harness task is a raw few-shot completion rather than a chat-templated request. BFCL run via the official bfcl_eval harness.

Eval command

GSM8K, thinking mode, via lm-evaluation-harness's native vLLM backend:

lm-eval run \
  --model vllm \
  --model_args pretrained=amd/Qwen3.8-27B-Quark-AWQ-INT4-W4A16,tensor_parallel_size=1,dtype=auto,gpu_memory_utilization=0.4,enforce_eager=True,trust_remote_code=True \
  --tasks gsm8k \
  --num_fewshot 5 \
  --gen_kwargs max_gen_toks=8192,do_sample=True,temperature=1.0,top_p=0.95,top_k=20,min_p=0.0,presence_penalty=0.0,repetition_penalty=1.0 \
  --batch_size auto \
  --log_samples

GSM8K, no-thinking mode. The prompt suffix <think>\n\n</think>\n\n is prepended to each answer field to suppress the model's thinking preamble (see custom task yaml below).

lm-eval run \
  --model vllm \
  --model_args pretrained=amd/Qwen3.8-27B-Quark-AWQ-INT4-W4A16,tensor_parallel_size=1,dtype=auto,gpu_memory_utilization=0.4,enforce_eager=True,trust_remote_code=True \
  --tasks gsm8k_nothink \
  --include_path <dir containing gsm8k_nothink.yaml> \

  --batch_size auto \
  --log_samples

--gen_kwargs on the CLI overrides the YAML task's own generation_kwargs defaults (greedy) with the instruct-mode recommended sampling parameters used for the non-thinking scores above.

Quantization command

python3 quantize_quark.py \
  --model_dir Qwen/Qwen3.8-27B \

Run from Quark/examples/torch/language_modeling/llm_ptq using AMD Quark with native qwen3_5 architecture support for AWQ (contributed upstream).

Serving

Requires a Quark-compatible inference runtime with W4A16Int4 scheme support (#48606 and #46110).

vllm serve amd/Qwen3.8-27B-Quark-AWQ-INT4-W4A16 \
  --trust-remote-code \
  --tensor-parallel-size 1 \
  --reasoning-parser qwen3
